Answer / 1

I think according to estimation & specification subject it
is upto 800 watts in 1 ckt.u can take number of points but
should not exceed 800watts. if the load exceeds more than
800 watts then it is taken for second ckt. in domestical
wiring

Answer / ahatesham

there are two types of circuit.
1.light circuit which contains light, fans & 5A sockets.
2.power circuit which have heavy loads like airconditions,
power sockets.
So.
For A light circuit max 10 points or 800w (1000W in some
books) whichever condition comes first.
For A power circuit 2 points or 3000w whichever comes first.

Answer / rk

12, which points light points or power points or both.

why square root 2 is multiplied with line voltage in selection of LA ie 11/sqrtroot3=6.35 kv and it is multiplied with sqrt2 ie 6.35 KV*sqrt2=8.9 kv we will select 9kv.my question is why we are multiplying with sqrt 2?
