Service disco for 100 amp house

[sw_ross]

I roughed in a “tiny home” back in March and put a 100A ML panel in it with the plans to put a 100A disco outside.
I was planning to have a 3R panel outside and backfeed a 100A breaker (using a hold-down kit). I can’t see any issues with that regarding the 2020 code?

They also want a generator inlet for backup power. I’ll have to get an interlock kit for the panel cover as well.

I bet you can find an outside disconnect/panel to act as both the disco and the interlock.

I got one just this Spring. Meter / Disconnect / Generator interlock and inlet. Feeds new main breaker panel in the basement. Yes, 2 main disconnects. ...and suspenders. Outside interlock has space for several breakers as well-- ideal spot to feed any outdoorsy outlets.

Can you use a meter main or does your poco supply or require a separate socket? Theres a homeline meter main with 4 breaker spaces and they have a interlock kit.

Can you give info on the product? I’m curious

The meter will be located separately so a meter/main isn’t going to work.

I got a QO 125amp main lug panel 6/12 spaces. I’ll put a 100a breaker in it as the main disconnect, then a 30a breaker with interlock kit for the generator. 30a inlet will go along side the panel.

Is this panel marked IAW 230.66?

I haven't done any tiny homes. I have seen some that are on trailers that people put on their properties and move them from place to place when they travel. Are these "mobile" homes required to have 100A services or can they be calculated and possibly fed with an 50A RV supply cord? If so, would a 50A flanged inlet on the outside of the structure with a power pole set near it be sufficient. If your panel was set on a pole, could you have (2) flanged inlets? One on the structure for an RV supply cord and (1) 30A flanged inlet on the pole for a generator using an interlock?

Imo, if it is a mobile home then it does

If this fits the definition of a mobile home, I think it does, then it can be cord and plug connected

550.10 Power Supply.

Yes, it does have a S.U.S.E. rating but it is only a subpanel. It will be fed with a 4-wire feeder from the meter/main location.
