What are the principles of hotel decoration and wiring?

Wiring problems in hotel decoration

1. Route selection: Many old houses originally used aluminum wires, and the decoration company has to tear them down and replace them with plastic steel wires. According to the new standard, the cross-sectional area of each household's incoming line shall not be less than10mm2, so for ordinary household decoration, 1.5 mm 2 conductor is enough for lamps and 2.5 mm 2 conductor for switch sockets. For the wiring of high-power electrical appliances such as air conditioners, you should take a 4-square-millimeter wire alone.

2. Buried wires: The power cord should be embedded during hotel decoration and office decoration, and should be laid by concealed pipes and trunking. Generally, the catheter is made of PVC rigid pipe, 45? On both sides of the slot. Cement slope protection, to prevent the above load is too large, flattening PVC board, affecting the later rerouting. There should be no joints and kinks in the wires in the pipe. If a slot is made in a reinforced concrete wall, it should be cut by a special cutter instead of an electric hammer. The electric hammer is easy to loosen the wall around the buried groove and destroy the wall structure. Be careful not to bury the wires directly in the ash layer, which is not only not conducive to the replacement of the lines in the future, but also very unsafe. The wiring of the bathroom must be completed before the waterproof sealing board. Wires must pass through pipes, and switches and sockets must be waterproof. The parallel distance between wires and heating, hot water and gas pipelines should not be less than 30cm, and the crossing distance should not be less than 10cm.

3. Wiring: In the wiring process, Zhengzhou Decoration Company has repeatedly emphasized the principle of "live wire enters the switch and zero wire enters the lamp holder"; Socket wiring should be "left zero and right fire, up grounding"; When connecting wires, you can't just wrap two wires together with insulating tape. You must tin the connection and press it with pliers to avoid the aging of the line due to uneven overcharge.
