During civil construction, the kitchen and bathroom are wired in accordance with the national standa

Building Codes. The electrical closed socks line should be wired in a laying way that meets the requirements of safety and fire prevention, the wire should be copper wire, the cross-section of each residential entrance line should not be less than 10 square millimeters, and the cross-section of the branch circuit should not be less than the square millimeter of car excitation.

The national standard does not apply. According to my current decoration industry. The socket is made with four square copper core wires. High-power water heaters should use six square ones.

Building Codes.

The electrical wiring should be routed in a way that meets the requirements of safety and fire prevention, the conductor should be copper wire, the cross-section of each residential entrance line should not be less than 10 square millimeters, and the cross-section of the branch circuit should not be less than square millimeters.

If you don't press the water heater, 4 square is enough, if you press the water heater, use 6 square one.

It depends on the specifications of the project that your developer is working on.

As is customary. 1. Generally, the design standards for returning houses (demolition houses) are relatively low. There is only one socket and one lamp in each room, only one entrance to the water and gas pipes, and there are no sanitary ware for drainage. (The general layout of kitchen and bathroom sockets is considered).

2. The design standards of commercial housing are relatively high. Generally, the layout of the socket in the room is reasonable, there are more lamp positions, the water supply pipe is set to each water distribution point (such as the water faucet to the kitchen and bathroom), the gas is still left in the household, and the drainage is set up with sanitary ware and floor drains. (The general layout of kitchen and bathroom sockets is considered according to 4mm2) 3. Villas.

Generally, according to the hardcover room, the equipment is relatively complete, and the design is according to high standards. (The general layout of kitchen and bathroom sockets is more than 4mm2, and multiple circuits are considered).

Please check whether the hidden information provided by the developer is consistent with the actual situation. Hydropower concealment data will generally be clearly marked with the circuit number and wire size. This is determined by the strength of the developer. Some of the worse developers do not provide electrical system diagrams.

It depends on the power of the electrical appliances used in the kitchen and bathroom, and usually 4-6 square copper core wires should be laid.

If you want to use a high-power instantaneous electric water heater in the bathroom, plus the power of the electric heater, it is best to lay a 10-square-meter copper core wire separately.

This is mainly based on the total electricity consumption of the electrical appliances and the point allocation to select the cross-section of the wire under the safe current-carrying capacity.
