So I have been lurking the site for a while and I now have an issue at work I could use some input on.
The gear we submited was 3 sections: pull, meter, main and distribution.
Instead we got gear with an extra section for the main.
soooo... we know have to move a 300kva xfmr which is fed from 500A breaker 480 delta, to 1000A 280/120Y distribution panel. we have to move it to a utility room about 50ft away.
it had to get "re-enginered" but the engineer drew up a 1200AS/1000AF for the primary, and no OCPD on the secondary?
NEC 240.21 - 10ft tap rule
408.16
450.3(A)
all seem to tell me that if there is a 1000AF on the primary, i need a disco on the secondary within 10ft?
THOUGHTs?
