Reasonable return
When an electrician enters a room, the first task is to determine the lamp position, lamp slot and reasonable pay-off. They will ensure that the wiring arrangement is reasonable and economical according to the owner's needs and engineering needs.
Payment index
For lighting, 1.5mm copper conductor is used for switches, 2.5mm copper conductor is used for sockets, and 4-6mm copper conductor is needed for air conditioners and water heaters. Don't forget, every room should ensure that each air switch controls a route according to the pay-off index, and so does the leakage switch!
Don't bury the thread directly
Remember! Don't bury plastic insulated wires directly in cement or lime, which will easily damage the insulation layer and cause leakage, which is very dangerous! At the same time, the iron pipe mouth through which the conductor passes should be covered with a retainer to prevent the conductor from being worn.
Strong and weak current separation
When dividing the line, it is best to separate the strong and weak current. Strong electricity is socket, weak electricity is network cable, communication cable, etc. High-power electrical appliances, such as water heaters and air conditioners, are safer to install, although there is no need to install overload switches.
multirow
Don't forget to leave more lines, such as audio lines and network lines, in case of emergency. If you are a northerner, you should also pay attention to the distance between wires and geothermal energy. Waterways should also ensure quality! Also, the main power switch must be selected, which is related to the safety of your home.
