That's what I do, since we're lucky enough to receive meter bases free from the POCO.

Inspector was busting our &&** on this job.

Outside disco is required. Inspector wanted a single disconnect which is not required by any POCO or local building codes. That narrows the number of available panels significantly.

After sitting down with inspector and his supervisor, and his supervisor we were able to agree on a basic meter combo with 2-200 amp mains and 8 slots.

By the way this service is for the guest house. The new guest pool and guest pool house were two much for the 200A service.

NYC encompasses several boroughs, including a large portion of Long Island. Many more single family houses than multifamilies in Manhattan (NYC proper).

we just mount the 400 amp with offsets to 2 200 amp exterior disconnects, one on either side and then into the house with 2 runs of service cable to 2 200 amp panels..

the can is mil-bank and the disconnects are Square D...

That's my normal method too. I have to pay about a bajillion dollars for a 400 amp meter can with built-in 200 amp disconnects.

I know this thread is old but I have a quick question about this. Is is allowed to have a 320 meter socket and have a 3inch nipple connected between the meter and the first disconnect. Then another nipple from the first to the second disonnect. Then feed through the first disco to get to the second one. I have a space issue on the outside of a home. Thanks for any help

I am looking at a quote I got yesterday for an ITE with 320 metering a 200 Amp. disconnect and a 200 amp disconnect w 8/16 distribution and feed through lugs. price = $886.00. Never heard of 3k for single phase 400 Amp. anything?

I believe you can't use the first disconnect as a chase for the second

Davethewave

Sealed gutter would be the way to go.

320 amp meter main with 2-200 amp breakers is an acceptable method for a 400 amp single phase service? I plan to feed a new 200 amp panel in the building and an existing 200 amp MLO panel in the building from the new meter breaker combo. This is a single phase service for a sorority. Am I missing anything?

I can think of exactly one justification for 400 amps residential service: a tankless electric water heater, which pulls 150 amps all by itself. In general, if you want 400a service in a home you have to justify it to the electric company--they want to be sure you aren't planning to take up smelting aluminum as your new hobby.

If you're going that way, most guys install two 200a load centers with a Siemens 400a meter base. The Siemens meter base has a 400a main breaker in it.

Almost every single home I do has a 400 amp service. Some are mostly just because of space requirements. Most need the amperage. Doing one. Ow that is a true 600 amp 80 space bolt on panel.
