I am currently switching an existing 400 amp. 277/480 volt circuit from the existing MDP to a second MDP to reduce stress on the existing gear.
The existing circuit consists of 4-750kcmil's in 4" conduit.
We ran 4" conduit from the second MDP to an existing splice box in order to catch the riser circuit.
I want to run parallel 3/0(cu) or either 4/0(al) or 250kcmil(al) per phase. There is just too little room to set up the puller and reels of 500cu or 750al.
We installed 10x10 wireway were possible to eliminate pulling thru pipe. We also installed pull boxes to interrupt the length of the run and for possible splicing.
Please advise!
