does come with 5 125a breaker

Asked by li March 23, 2019

No, the tenant breakers are sold separately. If 10KA interrupt rating is sufficient consider Q2125P.

Are the main lugs rated for 2 wire Parallel service or do we need to replace lugs.?

I have 4 unit apartment plus house meter , all have separate meter sockets , but disconnect bre...

Asked by peter April 15, 2017

Jeez a Siemen's rep should be able to answer this question. The question isn't about how he should rate the sub panels -THAT should be an electrician consult (and it seem like lowering the amperage should be fine). The question is whether the breakers are removable -something a rep should know right away. Caveat: I have not installed this product. But it seems to me that if the product accepts different Siemens breakers, one should be able to swap the breakers it comes with. Many Siemens breakers *of the same product lines* use the same size breaker housing from 15 amps to 100 amps, so it makes sense to be able to swap breakers.

need 9 gang for my multi units 3 3 packs together? prices

Asked by LL139c February 7, 2017

LL139c We do have 9 Gang Meters available through special order at your local Home Depot Pro Desk. Alternatively, feel free to browse the selection of Multi-Family metering at: http://www.homedepot.com/b/Electrical-Power-Distribution-Metering-Temporary-Power-Meter-Sockets/ As you are might already be aware, you will likely be limited in the metering you can use, depending on which Siemens models are approved for use by your local utility company.

Is this unit available in a 5 gang configuration? The meter housings also need to be lever bypass.

Asked by Journybug January 25, 2017

Journybug, This is a 5 gang meter socket, however, there is not an option to add a lever bypass. If you have any other questions feel free to reach out to our Retail Customer Support at 1-800-478-6346.
