Earth wire should be capable of carrying at least ,the full
load current . It can be of cu ,Al or GI.

Answer / kathiravan

actually the earth conductor capacity not lees than twice
that of FLC of connected load.In india normally cu and GI
flats are used more than 35kw where as open cu wires and GI
wires.The motto of earthing is that "Human Protection" means
the fault current has to be earthed in safe manner.

In secondary transmission i.e., in distribution side, supply for homes are connected through different phases in order to balance the 3 phase load. But in practical we saw nearby house doesn't have power due to single phasing. But other two phases give supply. How it's possible? it doesn't make "single phasing"?
