In a house wiring why we are using only one neutral wire and
so many phase wires from the main board, when the load is
common for both wires?

Answer / ajayan
Mr Karthik,In the 3 Ph system also we are having one
neutral wire.Neutral wire is the return path for all the
phases even it is single phase or three phase.

Answer / prasanna raj
The supply which we are receiving in our homes is Single phase supply only since the loads which we use are lesser rating (hardly 6A-8A)& Single phase is sufficient. In case of heavy loads, Three phase supply is required since the higher loads, single phase is not sufficient. Therefore 3 different phases are used in parallel with one Neutral common for 3 phases to complete the circuit path (in case of Star connection). In case of Single phase supply, there will be 1Ph + 1N. So, loads of our homes (ie; Fans, TV, Fridge, Iron Box, Motor etc) are all of Single phase having 2 terminals one for phase & one for neutral. So, for each & every load, we can connect to our supply's phase & neutral. No problem in that. But however, the common terminal(neutral of all loads)has to be grounded finally. Instead, rather than connecting each load P-N to Supply P-N & then Neutral to ground. We can directly connect supply's neutral to ground & supply's phase to load phase terminal, connecting the load neutral terminal to common grounding wire.

Answer / karthik raman.b
only one phase we r using in house wiring if u have 3 phase connection u will be have 3 phases.....from main board we r distributing the supply to different areas thats why we have many phase wires
