Answer / deepak prabhu

5 Hp motor usually comes in 3 ph only.and DOL starter of 3 phase is also available. Cable size doesn't depends on KVA of generators. In 3ph, 5Hp=3.7KW. =11A. By cosidering factor of safety we can use 4.0 sq mm copper cable.

Answer / mohammad farman khan-abu dhabi

5HP Motor are use as single phase on D.O.L or Star/Delta
connection as 3 phase. If you use single phase then total
load is 3.7kw so we can use 6mm sq cable .if you use in y/D
connection the required to use 4cx6 sq mm cable.

If the output of a 100kva, 415v generator is stepped up to 11kv with a 500kva transformer,can the transformer be Loaded above the source generator loading?
