why neutral busbar size is SAME of the phase busbar size
UPTO 200A IN LT PANELS
Answer / bele vijay kumar
For single phase circuits Neutral busbar size is equal to phase busbar & in 3 ph
systems it is either equal to phase busbars or lesser. It is determined on factor
such as Earthing of the Electrical system and the 3rd harmonics.

AC current is flowing in a wire in your home how can you measure it(name of the instrument)
For some transformers we are using solid neutral earthing while some others we are using resistance earthing why ?
where we use 1 phase & 3 phase supply ?what is major advantage using 3 phase over than single phase ?
what are the different types of transformers in present? which transformer is efficient?
