Default Mobile home service

We have a customer upgrading to a new mobile home. His current mobile home is fed from a 150 disconnect adjacent to the home. The new mobile home being delivered has a 200 amp main panel.


My question is does the manufactured home listing require it be fed with 200 amp conductors? The load calculation doesn't justifies the minimum 100amp service.

You can connect it with a smaller feeder, providing your load calculation justifies it. See 550.33(B).

We routinely connect mobile homes with a 200 Amp panel to a 100 Amp feeder, when they have gas heat, gas range, and minimal other loads.

As an owner I would want the full 200 amp capacity of the panel, however if the load is less than 150 amps I see no reason why you cannot use the existing 150 amp. panel with the appropriate conductors for that service.
