We are getting going building our house/shop/workspace building. Its large so we are going with a 600amp main panel and a few sub panels - one for the business end and a few in the residence and a 100amp for the pump house and outbuilding. The building will have an elevator, so we are doing 3 phase. There are a million panels out there and we just aren't sure what we really need. Do we need a main 600amp meter and breaker panel, then 3 200 amp breaker panels before we event separate into the subpanels?? I'm seeing meters for 600amp but they have like 5 meters on them and we just need 1. Have watched more electrical panel videos than any non-electrican should to no avail on what exactly we should buy, which is what I need help with. Since we are doing 3 phase, do all the sub-panels also need to be 3 phase or just the one thats carrying the big load with the elevator?
We have some electrician friends that will come in from out of state to help with wiring the house and subpanels and everything, but it sounds like shopping for the main panels is not their typical job so they haven't been much help. What all do we need? My husband had bought a meter not realizing he bought a 200amp meter which doesn't help us with the main panel :). However, I think we will use it for the subpanel going to the business part of the building so we can properly split the electric bill and some day if we convert it into a rental apartment it will be measured.
So. I need to shop. I need to get the different sized wire for running everything from the transformer to the main panel, from the main to the house utility closet that will run through the underground tubing, and panels and breakers, the works. My husband said he's fine getting it all hooked up if I can just get it bought (about as helpful as the other electricians!). So, If you were setting up this kind of service, what would you have on your shopping list and where to buy from?? The building where all the exterior panels will be going is being finished now so we can get the electrical attached and hooked up and finally get power out there. Thanks in advance
