How to select cable rating for HT/LT Panels
Answer / sudhakar g
If we take the LT panel incoming of the breaker is 1600A
and the transformer rating is 2000KVA.
We have to select the cable for that t/f to incoming
breaker in LT panel
400Sqmm AL cable carry 315A (POLYCAB) then we go for 6Runs
from T/f to LT panels
It is simple to cable runs of the T/F to I/c of the panel
