Square D EZ Meter-Pak Main Circuit Breaker Meter Center

The Square D EZ Meter-Pak meter center delivers reliable, versatile, and compact multi-metering equipment engineered for multi-unit residential and commercial construction. This configuration ships with a main circuit breaker rated 1600A, a 1200A bus, and a 65kA interrupt rating, making it suitable for demanding service entrance applications. It is rated 240VAC max (240/120V delta AC or 208Y/120V AC) in a 3-phase, 4-wire configuration, and is built to accept either overhead (OH) or underground (UG) service feed. The EZ Meter-Pak platform spans configurations from 225A up to 2000A, with main circuit breaker, main fusible switch, or main lug terminal box options available across the line, and this unit is UL Listed for code-compliant installation.

Key Features

  • Main Rated Current: 1600A main circuit breaker delivers high-capacity protection for multi-unit metering equipment.
  • Bus Rated Current: 1200A bus rating supports reliable power distribution across multiple meter positions.
  • Interrupt Rating: 65kA short-circuit interrupt rating provides robust protection for demanding electrical systems.
  • Voltage & Phase: Rated 240VAC max (240/120V delta AC, 208Y/120V AC), 3-phase/4-wire configuration for versatile service compatibility.
  • Service Feed Flexibility: Configurable for overhead (OH) or underground (UG) service feed locations.
  • Electrical Connection: Lugs accept 1 AWG through 6...300 kcmil aluminum/copper conductors, plus a dedicated ground lug.
  • Enclosure: Painted steel NEMA 3R enclosure protects internal components in outdoor and wet-location installations.

Square D EZM31600GCBC – Frequently Asked Questions

1) Will the Square D EZM31600GCBC meter center work on a 480V service?
No. The EZ Meter-Pak EZM31600GCBC is a 240VAC maximum device, wired for 240/120V delta or 208Y/120V, 3-phase 4-wire. A 480V or 480Y/277V service needs different equipment entirely. If your service is single-phase 120/240, the 3-phase 4-wire bus is also not the right configuration.
2) What size conductors can I land in the Square D EZ Meter-Pak 1600A main breaker section?
The lugs take 1 AWG through 6 runs of 300 kcmil, aluminum or copper, and there is a dedicated ground lug in the section. At 1600A you are using the multi-barrel capacity, so plan your service entrance conductor runs around parallel 300 kcmil sets.
3) Why is the main 1600A but the bus only 1200A on this EZ Meter-Pak?
That pairing is intentional. The EZM31600GCBC uses a 1600A main circuit breaker ahead of a 1200A bus, so the main is sized for the incoming service while the distribution bus feeding the meter positions is rated 1200A. Size the total connected meter-position load to the 1200A bus, not the 1600A main.
4) Can this Square D meter center be mounted outdoors?
Yes. The enclosure is NEMA 3R painted steel, which is the rain and sleet rating used for outdoor service entrance equipment. It is not a washdown or dust-tight rating, so indoor electrical rooms are fine too, but a hosedown or corrosive environment calls for a higher NEMA type.
5) Is a 65kA interrupt rating enough for my service entrance?
The EZM31600GCBC main breaker carries a 65kA short-circuit interrupt rating. Compare that against the available fault current at your service point from the utility transformer calculation. If your engineer's study shows available fault current above 65kA at this location, this unit is not adequate and you need higher AIC equipment or series-rated upstream protection.
6) Does the Square D EZ Meter-Pak handle overhead or underground service feed?
Both. The EZ Meter-Pak main breaker configuration is built to accept either an overhead (OH) or underground (UG) service feed, so the same equipment works whether the utility drops from a pole or comes up from a pad transformer.
7) Will the inspector accept this meter center as service equipment?
The EZM31600GCBC is UL Listed, which is what an AHJ looks for on service entrance and multi-metering equipment. The enclosure is NEMA 3R for outdoor locations, and construction is mercury free. Utility approval of the meter sockets themselves is separate and depends on your local power company's approved equipment list.
8) Should I order a main breaker, main fusible switch, or main lug meter center?
The EZ Meter-Pak platform offers all three across 225A to 2000A. A main circuit breaker section like the EZM31600GCBC gives you a resettable service disconnect with overcurrent protection in one device, which is the common choice for multi-family service entrance. A main fusible switch suits jobs where fuses are specified for coordination or higher interrupting duty. A main lug terminal box has no overcurrent device at all and is used where the service disconnect sits upstream.
9) Does installing the EZ Meter-Pak require pulling the unit off the wall to drill?
No. The mounting brackets rotate, so you can pivot them and drill your anchor holes without repositioning the section. On a 68.7 inch tall, 1600A main section that is a real time saver for a one or two man crew.
