the 15 amp fuse switch on the gentrans. does that only come into play with generator up and running?All my breakers are 20a,is it ok to let them stay 20a and then with generator running they would be only 15a,limited by the gentran fuse? the 3 way switch on the gentran in house position will carry the load on the circuit breaker as well,sorry if ive not been easy to understand.
