Commercial installation
Existing feeder into space is a 3? conduit with 4 # 350mcm
The total connected load for the tenant will be 265FLA
The Fuses at the Landlords MDP are 350amps
The main breaker within the tenant space is 400amps
All loads are at 120/208volt 3phase 4wire
Question is
Can the 350mcm conductors remain or do we have to up size to 500mcm?
Let us know as soon as possible, I am having a meeting with the inspector on Monday and would like to be equipped with the necessary feedback
Thanking you in advance for your input
