Square D CMELK4 – Frequently Asked Questions

1) What conductor sizes does the Square D CMELK4 lug kit accept?
The EZ Meter-Pak CMELK4 mechanical lug kit terminates AWG 2 through 600 kcmil, and the lugs are rated for either aluminum or copper conductors. That range covers most feeder and service entrance sizing at a 400A main lug termination, so you can pull parallel or single large conductors without swapping the terminal.
2) Will the CMELK4 lug kit fit any Square D meter center, or only EZ Meter-Pak?
It's an EZ Meter-Pak accessory. The CMELK4 is built to mount into EZ Meter-Pak multi-metering enclosures at the 400A main lug position, not into other Square D meter socket or load center lines. If the equipment on the job isn't EZ Meter-Pak, this isn't the termination kit for it.
3) Can I retrofit a 400A lug termination into an existing EZ Meter-Pak without replacing the whole meter center?
That's the point of the EZ Meter-Pak accessory lineup. Main and branch units can be reconfigured for replacement, extension, and design changes without swapping out the entire meter center, so the CMELK4 lets a property manager or contractor change the main termination on equipment that's already in service.
4) When do I use a main lug kit instead of a main breaker or fusible switch in a meter center?
A mechanical lug kit gives you a straight termination point with no overcurrent device in the meter center itself, which is what you want when the service disconnect and overcurrent protection sit ahead of the equipment. Choose a main breaker or fusible switch main instead when the meter center has to provide the disconnecting means and protection at that point. The CMELK4 covers the lug-only route at 400A.
5) Is the Square D 400A mechanical lug kit UL Listed for an inspected service install?
Yes, the CMELK4 is UL Listed, which is what an AHJ will be looking for on a service entrance termination. It is also a mercury-free design and RoHS EUR compliant with exemptions, which matters if the spec on the project carries material restrictions.
6) What is the exact part number to order for the 400A EZ Meter-Pak lug kit?
Order Square D CMELK4. It's a single-model kit, so there are no finish, handing, or size options to specify. Just confirm the meter center is EZ Meter-Pak and the main position is rated 400A.
7) How does the CMELK4 lug kit mount inside the meter center?
The kit mounts with two mounting holes into the compatible EZ Meter-Pak enclosure, so it's a bolt-in at the main lug position rather than a field-fabricated termination. No additional lug body is needed beyond the kit for that position.
8) Is the Square D CMELK4 made in the USA?
Country of origin on the CMELK4 mechanical lug kit is the United States, which is the detail institutional and government buyers working under domestic sourcing requirements need on the submittal.
