1/0 medium voltage. There are 3 vaults between switch and transformer. Between vaults A-B a true tape measures 331'. Between B-C measures 98' between A and transformer can't be measured to accurately but is 100' with a wheel. And finally between C and the switch is 8' and the duct bank is 7' below grade. Also the 3 vaults are pour in place about 6' square. Remember the wires have to be racked in each vault.

Well order 5000 ft then just sell the extra to the scrap yard .:thumbsup:

Rule if you cant get inside the manhole or box or transformer don't guess why cant you measure it .

Each conduit is going to be longer by stacking there not all the same length in transformer unless theres a vault under trans if you don't know how it was run underground its a guess.

How are you racking? Is it just to one side or do you have to do a complete loop around?

The reason I'am asking is my PM likes to order the absolute minimum I've always ordered 10% more plus a a few feet here and there. And of course if it's short I would get the blame. Any way this pull had a 4th vault we didn't know about. If I hadn't ordered extra wire we would have been short. I ordered 625'

I rounded up to 625 as well, so, the PM will add about 50'.
