Tapes Supplying a Transformer (Cables length)
Tapes Supplying a Transformer (Cables length)
(OP)
I'm planning to install new 2.5 MVA, 13.8/0.48 KV transformer. According to the NEC 240-21 Para. 3, the maximum tape condactors total length (Primery and secondary condactors) is no more then 25 ft. The Transformer equipped with oil immersed fuses at the primery (13.8KV).
Does anyone have an idea how can I have more cable length? does the fuses help to inlarge the cables langth?
Thanks to all.

Possibly a typo—maybe should be "tap conductor".

Part IX covers installation if systems over 600 volts.
250.180.
