## Insights

- [How much power does an electric truck depot need? Sizing from kWh per day and dwell time](https://entogo.ca/insights/electric-truck-depot-charging-power-sizing/): A 30-tractor depot running 180 mi a day at 2.0 kWh/mi moves 10,800 kWh to the batteries, needs 1,451.6 kW of average AC power across an 8-hour window and a 2,000 kVA transformer. Energy sets the floor; NEC 625.42 and CEC 8-106(10) set the code load.
- [How to size a battery storage interconnection: inverter kVA, transformer kVA and %Z](https://entogo.ca/insights/battery-storage-interconnection-transformer-sizing/): A 2 MW battery inverter holding IEEE 1547 reactive capability is a 2222 kVA source, so it needs a 2500 kVA transformer, 2673 A of conductor under NEC 705.28, and 65 kA gear once the 600 V bus fault duty reaches 44,403 A.
- [What size transformer and switchgear does a DC fast charging site need?](https://entogo.ca/insights/dc-fast-charging-site-transformer-switchgear-sizing/): A DC fast charging site is sized from AC input kVA, not DC output kW, and EVSE loads carry no demand factor. Four 150 kW plus eight 350 kW dispensers draw 3,615 kVA, needing 5,000 kVA of transformer and two 3,000 A mains at 480 V.
- [How long can transformer secondary conductors be? NEC 240.21(C) tap rules and CEC 26-256](https://entogo.ca/insights/transformer-secondary-conductors-nec-240-21c-tap-rules/): Transformer secondary conductors get no next-size-up rule. NEC 240.21(C) allows 10 ft and 25 ft runs with ampacity floors of one-tenth and one-third of the primary device times the voltage ratio; CEC 26-256 instead demands 125% of rated secondary current at any length.
- [208, 480, or 600 volts? Choosing a facility distribution voltage](https://entogo.ca/insights/choosing-a-facility-distribution-voltage/): North American facilities are served at 120/208, 277/480, or 347/600 volts. A higher voltage moves the same power at lower current, cutting conductor size and losses while adding transformer and safety cost. Here is how to match the voltage to the load.
- [De-energized taps or a load tap changer? Specifying transformer voltage regulation](https://entogo.ca/insights/transformer-voltage-regulation-tap-changers/): A transformer needs voltage regulation when source voltage swings beyond about 5 percent or loads are voltage-sensitive. Fixed de-energized taps correct a standing offset; on-load tap changers hold output steady continuously. Here is how to choose and specify.
- [What transformer impedance should you specify? How %Z shapes fault current and voltage drop](https://entogo.ca/insights/transformer-impedance-percent-z-selection/): Transformer percent impedance (%Z) sets how much fault current the secondary can deliver and how far voltage sags under load. Lower %Z means higher available fault current and better regulation; higher %Z limits fault duty but drops more voltage. Here is how to choose it and what to specify.
- [Solidly grounded, resistance-grounded, or ungrounded? Choosing a power system grounding scheme](https://entogo.ca/insights/power-system-grounding-scheme-selection/): Most North American facilities are solidly grounded, but resistance grounding can keep a plant running through a first ground fault. How to choose among solidly grounded, high-resistance grounded, and ungrounded systems, and what each requires under the NEC and IEEE 142.
- [Do you need a K-rated transformer? How to calculate K-factor](https://entogo.ca/insights/do-you-need-a-k-rated-transformer/): Calculate K-factor from the load's harmonic spectrum, then specify the next UL K-rating at or above it. A 150 kVA IT panel with 70 percent third harmonic gives K = 7.83, so K-9. A standard unit is derated to 81.5 percent and the neutral carries 576 A, 160 percent of phase current.
- [DC-coupled vs. AC-coupled solar-plus-storage: how to choose](https://entogo.ca/insights/dc-coupled-vs-ac-coupled-solar-storage/): DC coupling ties the battery to the array's DC bus behind one hybrid inverter and recaptures clipped energy; AC coupling gives solar and storage their own inverters and easier retrofits. The right choice depends on whether the two are built together.
- [Should your facility take medium-voltage service? Primary metering and customer-owned substations](https://entogo.ca/insights/medium-voltage-service-primary-metering/): Taking medium-voltage utility service means owning the step-down transformer and the substation behind it, in exchange for a lower primary-metering rate. It pays off for large, steady loads but shifts transformer losses, maintenance, and protection to the buyer. Here is how to weigh the trade-off.
- [NEMA vs. IP enclosure ratings: specifying outdoor power equipment](https://entogo.ca/insights/nema-vs-ip-enclosure-ratings-outdoor-power-equipment/): NEMA enclosure types and IEC 60529 IP codes both rate ingress protection, but they are not interchangeable — NEMA 250 also tests corrosion, icing and hosedown, which the IP code omits. For North American power equipment, specify a NEMA type and treat IP as a supplement.
- [Grid-forming vs. grid-following inverters for battery storage](https://entogo.ca/insights/grid-forming-vs-grid-following-inverters-battery-storage/): Grid-following inverters follow an existing grid voltage, while grid-forming inverters set their own voltage and frequency so they can ride through weak grids, island, and black-start. Here is how to tell which one a battery storage project needs and what to specify.
- [Total owning cost of a transformer: how to evaluate losses in a bid](https://entogo.ca/insights/total-owning-cost-transformer-loss-evaluation/): Total owning cost adds the capitalized value of no-load and load losses to the purchase price. At 14.53 cents per kWh over 10 years the A factor is 8.54 dollars per watt and the B factor 1.73 at rated load, the break-even A factor is 6.30, and a bid 3,400 dollars dearer wins by 1,208 dollars.
- [Gas-insulated vs. air-insulated switchgear: how to choose](https://entogo.ca/insights/gas-insulated-vs-air-insulated-switchgear/): Gas-insulated switchgear seals live parts in gas for a compact, low-maintenance lineup; air-insulated switchgear stays larger but fully serviceable and gas-free. The right choice turns on footprint, environment, voltage class, and tightening SF6 rules.
- [LFP vs. NMC batteries for stationary storage: how to choose](https://entogo.ca/insights/lfp-vs-nmc-batteries-stationary-storage/): LFP and NMC are the two lithium-ion chemistries behind most stationary storage. LFP leads on cycle life, thermal stability and cost per kWh; NMC packs more energy into less space. Here is how to match chemistry to a project.
- [Switchboard vs. switchgear: how to choose (UL 891 vs. UL 1558)](https://entogo.ca/insights/switchboard-vs-switchgear-ul-891-vs-ul-1558/): Switchboards and low-voltage switchgear both distribute power below 1000 V, but they are built and tested to different standards. Switchgear (UL 1558) uses draw-out breakers and a short-time withstand rating that supports coordination; switchboards (UL 891) are simpler and more economical for less demanding loads.
- [Selective coordination: when a project needs a coordination study](https://entogo.ca/insights/selective-coordination-nec-requirements/): Selective coordination means the overcurrent device nearest a fault opens first, so one short circuit does not cascade into a wider outage. The NEC requires it for emergency, standby, and other critical loads, verified with a time-current-curve study.
- [Air-cooled vs. liquid-cooled battery storage: how to choose](https://entogo.ca/insights/air-cooled-vs-liquid-cooled-battery-storage/): Battery cells age faster when they run hot, so a BESS cooling architecture largely decides its lifespan and footprint. Air cooling is simpler and cheaper; liquid cooling holds tighter temperatures for dense, high-throughput sites. Here is how to choose.
- [Do you need a microgrid? Islanding, resilience, and what to specify](https://entogo.ca/insights/when-does-a-commercial-microgrid-make-sense/): A microgrid lets a site keep critical loads running through an outage by islanding onto local storage and generation. It makes sense where outage cost is high or grid capacity is constrained, and it requires grid-forming inverters, a microgrid controller, and utility-approved protection.
- [Available fault current and equipment short-circuit ratings: what to calculate and specify](https://entogo.ca/insights/available-fault-current-sccr-what-to-specify/): Available fault current is the maximum current a bolted short circuit can push through a system at a point. Every breaker, switchboard, and control panel needs a short-circuit current rating at least equal to it, and non-dwelling service equipment must be field-marked with the value under NEC 110.24.
- [Harmonic distortion: what IEEE 519 requires and how to meet it](https://entogo.ca/insights/harmonic-distortion-ieee-519-limits/): Harmonic distortion from VFDs, EV chargers, and data-center power supplies can breach IEEE 519 limits and quietly overheat neutrals, transformers, and switchgear. This guide explains the 519-2022 voltage and current limits and how to specify mitigation before it becomes a field problem.
- [How to size a battery energy storage system: power vs. energy](https://entogo.ca/insights/how-to-size-a-battery-energy-storage-system-power-vs-energy/): A battery energy storage system is sized with two independent numbers, power in megawatts and energy in megawatt-hours. Their ratio is the C-rate, which fixes how long the system runs at full output and drives cost, cooling, and site design.
- [EV charging load management: sizing a site without a service upgrade (NEC 625.42, CEC 8-500)](https://entogo.ca/insights/ev-charging-load-management-service-upgrade/): NEC 220.57 counts every EV space at 7,200 VA or nameplate, whichever is greater, so 200 Level 2 spaces calculate as 1,440 kVA and 2,165.1 A of design current. An EVEMS capped at 400 kW brings the transformer from 2,000 kVA to 500 kVA, and CEC 8-106(11) can drop the EVSE load from the calculation entirely.
- [Interconnecting solar and storage to the grid: what IEEE 1547-2018 requires](https://entogo.ca/insights/ieee-1547-der-grid-interconnection/): Connecting solar or battery storage to the North American grid means meeting IEEE 1547-2018 for DER behavior, using a UL 1741 SB certified inverter, and passing a utility interconnection review that scales from a fast-track screen to a full study. Here is how the pieces fit.
- [Arc-resistant switchgear: when it's required and what an IEEE C37.20.7 rating means](https://entogo.ca/insights/arc-resistant-switchgear-ieee-c37-20-7-rating/): Arc-resistant switchgear redirects the pressure and heat of an internal arcing fault away from anyone standing nearby, tested to IEEE C37.20.7. It is specified where crews work close to energized medium-voltage gear and calculated incident energy is high.
- [Transformer efficiency standards: what DOE 10 CFR 431 requires and the 2029 update](https://entogo.ca/insights/transformer-efficiency-standards-doe-10-cfr-431/): US distribution transformers must meet DOE 10 CFR 431 minimum efficiency, defined at 35 percent load for dry-type units and 50 percent for liquid-immersed. A 2024 final rule raises those floors for units built on or after April 23, 2029, and here is how the rules work and what to specify.
- [Power factor correction: how to size a capacitor bank and clear a utility penalty](https://entogo.ca/insights/power-factor-correction-utility-penalty/): Power-factor capacitor sizing uses Qc = kW x (tan phi1 - tan phi2). An 800 kW load at 0.78 power factor needs 379 kVAR to reach 0.95, so a 400 kVAR bank is specified. BC Hydro's graduated surcharge reaches 16 percent below 80, Hydro One bills on 90 per cent of kVA, and PG&E adjusts 0.06 percent per point off 85.
- [Dry-type vs. liquid-filled transformers - how to choose](https://entogo.ca/insights/dry-type-vs-liquid-filled-transformers/): Dry-type transformers cool with air and solid insulation while liquid-filled units use mineral or less-flammable oil. The right pick turns on installation location, fire and code rules, voltage class, efficiency, and maintenance - not on which type is generally better.
- [Battery storage fire safety: what NFPA 855 and UL 9540A require](https://entogo.ca/insights/battery-storage-fire-safety-nfpa-855-ul-9540a/): Lithium-ion battery storage in North America is governed by NFPA 855 and UL 9540A. NFPA 855 caps individual units at 20 kWh and requires three-foot separation unless UL 9540A large-scale fire-test data proves a fire will not spread, which shapes how a BESS is sited, spaced, and permitted.
- [Metal-clad vs. metal-enclosed switchgear: how to choose](https://entogo.ca/insights/metal-clad-vs-metal-enclosed-switchgear/): Metal-clad switchgear uses drawout breakers and grounded metal barriers between every compartment; metal-enclosed interrupter switchgear is simpler and built for lower fault duty. Here is how North American buyers match construction class, voltage, and fault duty to the application.
- [How do transformers get approved for use in Canada?](https://entogo.ca/insights/transformer-approval-certification-canada/): Before a transformer can be energised in Canada, the Canadian Electrical Code requires it to be "approved" — either certified by an SCC-accredited body (a CSA, cULus or cCSAus mark) or field-evaluated to CSA SPE-1000. A US-only "UL Listed" mark is not enough. Here is how the approval system actually works.
- [Sizing transformer overcurrent protection (NEC 450.3(B) & CEC 26)](https://entogo.ca/insights/transformer-overcurrent-protection-fault-current/): How to size transformer primary and secondary overcurrent protection to NEC Table 450.3(B) and CEC Section 26 (Rule 26-254), and how to find the available fault current at the secondary for downstream AIC / SCCR — with worked US and Canada examples.
- [How are transformers sold? Distribution channels, reps and the 2026 demand surge](https://entogo.ca/insights/how-transformers-are-sold-distribution-channels/): Transformers reach buyers through four channels: direct OEM sales to utilities and EPCs, independent manufacturers' reps, two-step electrical distribution, and online procurement. With a global market near US$61B and 30% power-transformer supply deficits, the sales channel and sourcing have become strategic.
- [How to size a transformer: a practical guide to kVA selection](https://entogo.ca/insights/how-to-size-a-transformer-kva-selection/): How to convert a real electrical load into the right transformer kVA: the calculation, the standard ANSI/IEEE rating ladder, and the margins for continuous duty, future growth, ambient and altitude that sit between calculated load and nameplate.
- [Grain-oriented electrical steel: why one Pennsylvania mill sets the clock for the North American grid](https://entogo.ca/insights/grain-oriented-electrical-steel-supply-chain/): Every power transformer needs grain-oriented electrical steel (GOES), and the DOE estimates it is roughly a quarter of large-transformer cost. North America has one domestic producer — Cleveland-Cliffs' Butler Works. This is the supply chain behind the one-to-four-year lead time.
- [Power equipment for AI data centers: what changes when racks hit 100 kW](https://entogo.ca/insights/ai-data-center-power-equipment-2026/): AI training loads have pushed rack densities past 100 kW and substation lead times past three years. This is what each layer of the data-center power chain — transformer, switchgear, energy storage — now has to deliver, and where projects actually compress the schedule.
- [What does it actually cost to install a DC fast-charger station? A 2026 breakdown](https://entogo.ca/insights/dc-fast-charger-installation-cost-2026/): Public ranges for "DC fast-charger installation cost" span $50,000 to over $1 million per site — too wide to be useful. The Atlas/Paren analysis of NEVI awards, NREL deployment data and Rocky Mountain Institute rate-design work converge on a tighter cost stack, and on which lines actually move.
- [How long are transformer lead times in North America in 2026?](https://entogo.ca/insights/transformer-lead-times-north-america-2026/): In 2026, transformers in North America's merchant market commonly take one to four years to deliver — driven by electrical-steel (GOES) constraints, surging data-center demand and an aging fleet. Manufacturers with their own source factory, such as Entogo (16–24 weeks, ANSI/IEEE spec), sit largely outside that queue.
- [Solar-storage-charging integrated systems, explained](https://entogo.ca/insights/solar-storage-charging-explained/): A solar-storage-charging system pairs on-site PV, a battery and EV charging behind a single grid connection, so charging draws on stored solar instead of the service entrance — enabling fast charging at sites whose utility supply could not sustain it alone.
- [How behind-the-meter battery storage cuts demand charges](https://entogo.ca/insights/cut-demand-charges-with-battery-storage/): Demand charges are billed on a facility's highest power draw, not its total energy use. Behind-the-meter battery storage discharges during those brief peaks to cap the demand, and shifts cheap off-peak or solar energy into expensive on-peak hours — lowering both parts of a commercial electricity bill.
- [AC vs. DC EV charging: what North American sites need](https://entogo.ca/insights/ac-vs-dc-ev-charging-north-america/): AC charging is slower, cheaper and ideal where vehicles dwell for hours; DC fast charging delivers high power for short stops but needs far more grid capacity. Matching charger type to dwell time, site load and budget is the first decision in any EV charging project.
- [Prefabricated substations vs. conventional builds: when modular wins](https://entogo.ca/insights/prefabricated-vs-conventional-substations/): A prefabricated substation arrives as a factory-built, factory-tested package that drops onto a prepared pad, compressing months of on-site construction into days. For space-constrained, schedule-driven or repeatable projects, the modular approach usually wins on time, quality and total cost.
