Now most home decoration will choose to wall wiring, therefore, the nationwide assembly of electrical and intelligent cooperation to remind consumers that the decoration must pay attention to the reasonable layout of the circuit to reduce the safety hazards and waste caused by repeated disassembly. Because furniture and household electrical appliances can be changed at any time, once the wires buried in the wall are installed, no one wants to chisel in the wall to replace them. Therefore, it would be better to put the loop in advance and distribute the loop in advance. This will save at least ten years of use. Electric troubles.
Asked for completion circuit
First of all, we must clearly understand the electricity environment in our home. Whether it is the decoration of a first-hand house or a second-hand house, be sure to ask the real estate developer or decoration company for the "completed circuit diagram." In this way, you will be able to make it clear that your home will be refurnished in the future. Whether the loop diameter is adequate or not; how the pipeline is going and when it is hung on the wall, there is no need to worry about hitting a buried trunk.
Inbound line allowance
Second, before the renovation, it is necessary to clearly understand how much the current entrance line diameter is. Most developers will now install a 6 square -10 square entry line. We should note that the entrance line must not be less than 6 square feet. Consumers can estimate the total electricity consumption based on home appliances. Estimates must have margin (at least to meet the demand for electricity growth in the next 10 years), because the amount of home appliances will certainly increase in the future, and the power is certainly increasing. Communicate with the designer, let him calculate the power load, and then distribute the circuit.
Select wire diameter according to purpose
When allocating loops, it is generally divided into several loops according to different functions: lighting, common power sockets, air conditioner power sockets, kitchen and bathroom power sockets should be set up separately. The following is a design proposal for the home part loop:
Illumination: 1.5 sq. ft. (Using 2.5 square lines for all 800 watts)
Ordinary power socket: 2.5 square
Air conditioning socket: a single wall-mounted circuit can be selected 2.5 square, multiple wall-mounted circuit should choose 4 square or more, floor-standing air-conditioning circuit should choose 4 square
Kitchen circuit: 4 square
Instant-type water heater: Set up the circuit separately, with 4 square wires
In addition, you need to remind everyone that some high-power appliances, such as electric water heaters, air conditioners and the like must pull a separate circuit (such as instant-type electric water heater not only a separate circuit, but also use 4 square wire) Don't avoid tying up multiple electrical appliances in series on a single circuit to save money. This can easily cause overload. Once the line is overloaded, the wires inside it are prone to heat, causing short circuits or electrical fires. The consequences are disastrous.
Air switch not greedy
Home distribution boxes, developers are generally pre-installed behind the door, not suitable for their own casual changes in location. We must pay attention to whether or not a protective device (air switch, also called circuit breaker) is installed. In the event of a short circuit or overload, it will trip automatically to prevent accidental leakage. The air switch specifications in the distribution box cannot be selected too large, otherwise it will not trip when there is a circuit problem. It is safer for the designer to make a choice based on the electrical load calculation current.
