Aoa , PW members and viewers, as you know now a days it's season of load shedding and Electricians demands huge amounts and after taking advances they delay you work.
Beside the electricians high demands and unavailability, they will do wiring from out side the wall, using saddlers. which will definitely destroy the look of your home.
so i decided to do it my self, i used a steel wire and did it my self from the inside to existing PVC pipes.
i ll post a few pictures of them. and a diagram i have followed to understand the circuit.
