Meter Socket / CT Metering Enclosure

200 – 1200 A · stainless / NEMA 3R / 4X

Entogo meter socket and CT metering enclosure, stainless steel

Overview

Meter sockets and current-transformer (CT) metering enclosures for residential, commercial and utility service — 200–1200 A, ringless or ring-type, in 304/201 stainless or galvanized steel, NEMA 3R/4X. Designed to UL 414, UL 50/50E and ANSI C12.7; UL/CSA certifiable.

These meter sockets and current-transformer (CT) metering enclosures serve revenue metering points from 200 to 1200 A, 60 Hz. Self-contained meter sockets cover services up to about 320 A, while CT-rated enclosures use current transformers to scale measurement for larger 400 – 1200 A commercial and utility services per ANSI C12.7.

Built from 304 / 201 stainless steel — NEMA 4X for coastal, corrosive and washdown sites — or galvanized steel, in ringless or ring-type configurations with optional lever bypass, dimensions and layout are customized to the local utility standard. Designed and built to UL 414 (meter sockets) and UL 50 / 50E (enclosure), with UL (cULus) / CSA certification available on request.

Key features

  • Self-contained meter sockets (≤ 320 A) and CT-rated metering enclosures (400 – 1200 A) for revenue metering points.
  • Designed and built to UL 414 (meter sockets) and UL 50 / 50E (enclosure) with ANSI C12.7 metering, 60 Hz — UL (cULus) / CSA certification available on request.
  • Durable stainless steel (304 / 201) for corrosion resistance — NEMA 4X for coastal and washdown sites — or galvanized steel.
  • Ringless or ring-type, lever-bypass options; dimensions and layout customized to the utility standard.
  • Suitable for indoor and outdoor metering at residential, commercial and utility service points.

FAQ

Common questions

When do I need a CT metering enclosure instead of a meter socket?
Self-contained meter sockets handle services up to about 320 A. Above that, a CT-rated metering enclosure uses current transformers to scale the measurement — typically for 400 – 1200 A commercial and utility services, per ANSI C12.7.
What materials and NEMA ratings are available?
304 / 201 stainless steel or galvanized steel, in NEMA 3R for general outdoor use or NEMA 4X (stainless) for coastal, corrosive and washdown environments, 60 Hz.
Can the layout be customized?
Yes — dimensions, bus, ringless/ring-type and lever-bypass arrangement are built to the local utility (EUSERC and others) standard. Designed to UL 414 / UL 50; UL (cULus) / CSA certification available on request.
