In interior decoration, one step that can't be ignored is to master the basic knowledge of decoration electrician, which plays a very key role in the decoration of the whole indoor circuit. Next, let's introduce some basic knowledge about decoration electrician, so that everyone can know more about decoration electrician. Let's read it together.

First, the basic knowledge of decoration electrician

1. Electrician shall determine the lamp position, lamp trough and pay-off (reasonable arrangement shall be made according to the owner's requirements and engineering needs). Electricians check whether the wire arrangement is reasonable, pay-off takes shortcuts to save wires as far as possible, whether the bottom connector is straight, whether the wire connector is reasonable, whether the pay-off is standardized, and whether the straight-through arrangement is made.

2. Pay-off: lighting lamp, switch, copper core wire:15m2, copper core wire of socket: 2.5m2, air conditioning wire and water heater: 4-6m2. Overall system: according to the pay-off index of the room (that is, how many lines are there), each air switch controls one circuit, and one or several leakage switches mainly depend on the voltage (generally one leakage switch is arranged).

Second, the basic knowledge of decoration electrician-matters needing attention of decoration electrician

1. Plastic insulated wires are not allowed to be directly buried in cement or lime powder layer for underground wiring. Because it is buried in cement or lime powder layer, the insulation layer of the conductor is easy to be damaged, causing large-area leakage and endangering personal safety. The pipe mouth of the iron pipe through which the wires pass must be covered with a plastic or wooden retainer, because the electromagnetic force generated when different wires pass through the current will make the wires slightly shake and easily wear the insulation of the wires in the iron pipe.

2. When wiring, it is generally better to separate strong and weak current. Strong electricity refers to sockets, and weak electricity refers to network cables and communication lines. For high-power electrical appliances, such as water heaters and air conditioners, there is no need to install overload switches, but the safety factor is higher. Some residential areas are compulsory and should be accepted by the management office.

3. Leave as many wires as possible, such as audio cables and network cables, in case of emergency. By the way, if you are a northerner, you must pay attention to the distance between electric wires and geothermal energy, and the decoration of waterways is the same. You must guarantee the quality. The main switch of the power supply is the main switch of your home. After unplugging, it can cut off the power for your whole family. The source of all buried wires is this master switch.

Third, the decoration electrician decoration points

1. entrance line: the entrance line was laid when the house was handed over, and it is not necessary to re-lay it. If it's an old house, it needs to be replaced with one of more than 6 square meters.

2. Socket loop: generally, 2.5 square wires are selected for the socket loop. If there are many kitchen appliances that may be used at the same time, it is recommended to use 4 square wires.

3. Lighting circuit: The lighting circuit is generally 1.5 square meters, and it is 2.5 square meters if there is a large chandelier.

4. Air conditioning circuit: choose 2.5 square meters to hang up, each air conditioner has an independent circuit; The cabinet is 4 square meters; The central air conditioner selects 6 square lines according to the power.

The above is the basic knowledge of decoration electrician introduced by Bian Xiao. I believe everyone has a preliminary understanding of the basic knowledge of decoration electricians. In their spare time, they can learn more about electricity, which is of great help to interior decoration.
