1. The right tools
You will need wire cutters wire strippers, a set of screwdrivers a, cordless drill and a roll of masking tape. The Lightning conductor is the first in the safety chain, then comes the 30 milli amp circuit breaker and then the RCD switches. Electrical standards today require a minimum number of RCD switches depending on the size of your home. There must be at least two RCD switches for a house of less than or equal to 35 square meters.
The rating of each RCD depends on the type of circuit it has to protect. Lighting circuits require 10 amps, circuits requiring 10 to 16 amps are for a washing machine, dishwasher, water heater, tumble dryer and an oven rating is 20 amps for a hob and an electric cooker, the rating is 32 amps.
There may be other circuits in the system. Lights may be controlled by remote control with several push buttons. There are 24-hour programmers for off-peak electricity as well as minute timers which turn off the lights automatically.
