Hello,
I have a 200 amp service on a double wide mobile that was installed with 2 - 200 amp disconnects installed in line for additional space. The have 4/0 aluminum in the mast to a 200 amp meter / disconnect combo then from the feed through lugs, they go to the second 200 amp 20 circuit disconnect. Does 230.80 apply? Does the mast need to be sized for 400 amp?
Thanks
