I am an electrical inpector. I have a client who has installed a 9 gang meter socket that he recieved special from factory with a 400 A disconnect breaker. He also recieved the meter with a 3/0AWG nuetral conductor as well as i clad phase connections for the same rating. Due to the fact that he recieved the meter socket from factory with thes 3/0 rated conductors he also used 3/0 from the disconnect to his service point.
My question lies in if the disconnect infront of all the meters is a form of protection or if it is just for isolation? Is the 3/0 suitable for the 400A breaker if it is just for isolation?
My understanding is that 400A requires a 400MCM service conductor. These questions arise due to the fact that these things were recieved from factory.
My initial instinct is to tell him he needs to rte his conductor to the 400A disconnect breaker but would I be wrong? would he also need to change 3/0 on the secondary of the breaker?
