Once past the service disconnect, the sky is the limit.
I wouldn't suspect. A joke sometimes doesn't translate.Oh god no, the maximum run length is 60'.
There's a couple ways to calculate multifamily loads. Art 220 allows you to apply demand factors to things like ranges, dryers, water heaters, and stuff like that. There's a table in there somewhere in 220 just for that purpose.Could any of you guys help me out with another question?
Ive done my service calculation for the units, and they will draw max 75 amps, but I know that isn't the case all of the time. Anyways, I figured each unit will have a 100 Amp panel, and for the House panel I was going to install a 60 panel for common areas and outdoor lighting and power. For the meter bank and service drop, do I add up the combined service calculations to get the wire size? or is there a specific calculation I need to use. I have looked endlessly at the code and cannot find the answer I'm looking for.
Nope, you can run it up the wall or through studs. Use nailplates as needed.OK thats awesome to hear. I was going to use a 4 space meter bank with disconnects for each panel they're feeding. Does the cable need to be in conduit while running through the basement, and up the walls?

I just want to make sure you understand this part due some meter socket do have bypass lever in there but for your situation it will not be a issue but if you have main breaker below the meter unit then the conductor or cable can be unlimited on distance.Hey there, I am wiring a 3 family in massachusetts, and I am not a wiz on residential wiring as I mainly do industrial and commercial. Anyways, my question is How far can my service entrance cable go between the meter disconnect and the panel. It is a 3 family, and I want to put the panels in their respective units, 1st,2nd and 3rd floor. The house panel would be installed in the basement.
I heard some area they will required the load side of service conductors to be in either MC or in conduit.Check with the AHJ. Around here, we cant use AL except for the riser, and we can't run in the walls through one unit to the other.
They were going to have us sleeve SER with greenfield on one, we ended up going underground and around. Didn't want one tenant to be able to tap into the others power.I heard some area they will required the load side of service conductors to be in either MC or in conduit.
I am sure some AHJ are pretty strict with multi family units.
Better run FR cable insteadThey are no longer SE (service entrance), they are now feeders.
