Allowable 9-Gang Meter Install?

[CharlieFer]

I have experience with the EZ Meter-Pak system from Square D that just all bolts together. What other allowable ways is there to design and install a 9 gang for a 9 unit building? Are they more cost-effective, or is the cost-savings just overcomplicating it and you'll waste more time on the field? I'm always looking to learn from smarter individuals, thanks guys

EZ Meter-Paks are the preferred way the contractors I have worked with have done it.

Unless you have utility rules that say otherwise, there is nothing in the NEC that prohibits coming off a service disconnect into a trough or bussed gutter and into individual or multi gang meter sockets. Im not saying it would be worth doing, just that you can

Yep, typically ends up taking more physical space and more labor from what I've seen.

So there’s my next question, in the trough how do you branch out to all the individual meters? A huge 10 port Polaris? Taps? A bussed gutter huh? I don’t think I’ve ever seen that, sounds custom, and a lot more work

# units never equal # meters

Definitely more labor, so what the customer thinks they save in parts, they’ll spend in labor

Yeah I was in a hurry typing that out so I forgot to count the house meter

how do you branch out to all the individual meters?

Buy Multi-Wire Lugs (4 or more wires per lug

Just kidding

Be mindful that regardless of what you do, you will need a main disconnecting means, as 9 disconnecting means is not allowable.

I was gonna say, that seems a bit sketch for connecting live service wires

Correct, hence why I wondered how else people were designing multi-gang meter assemblies besides using EZ MeterPaks

Many ways to do it with connectors, terminal blocks, Polaris connectors, H- taps.

Busses gutters are real convenient:
