I need to repair this service before i can add onto it, i need to repair the damaged service conductors (2500 amp bus duct) bus duct consists of a 90 degree elbow that stubs into a transformer vault.
Bus duct is old from 1969 no luck finding any replacement.
I am thinking of removing bus duct, installing nipples out of the back of the switchgear to a large weatherproof junction box in the vault, running my service conductos off the busbars through nipples and jbox and coming out of the bottom of the jbox with chase nipples and having utility connect directly to transformer.
I would like to drill and bolt mechanical lugs onto the existing bus bars in switchgear and run 6 sets 600kcmil conductors for 2500 amps.
Anyone see any isses with that?
Are the busbars listed to be drilled and have mech. lugs bolted to.
