I was going to do some electric work for a relative, it is a 2 family home. I was checking the system, it is a main disconnect that has two 150 amp buss fuses in it. The main disc is rated at 200 amps. the 2 breaker boxes are 75 amps each. The service entrance cable is 2/0. Shouldn't there be only 2 75amp fuses in that box?. Also this is an old Wadsworth system, with a lot of subpanels that have been added over the years. What I am eventually going to do is replace the whole system with 200amps coming in, & 2 100 amp breaker panels.
