| question is quite out of context.
First of all entire wiring circuit is earthed, s there is no question of having seperate earthed and non earthed connection.both power n lighting r earthed
but i guess the maker of this question is expecting the answer as follows:
as earthing prevents electrical shocks, there is higher probability of a person getting a shock frm a power connection if it is not earthed,whereas if lighting circuit is nt earthed it will damage only the lighting device , wil nt gv electrical shock to any person |
