Anonymous users2024-01-24Ceiling wires are threaded with PVC pipes.
Theoretically, PVC is flame retardant, once the wire catches fire, then the PVC flame retardant pipe can stop the fire from continuing to expand, because PVC is not easy to burn.
Analyze the hazards from two points:
1.Assuming the room is newly renovated, then there will be two lines of defense for the fire caused by a short circuit or overload, the circuit breaker and the insulation of the wire, unless the circuit breaker is not the right specification or the wire is not up to standard, the fire in your home may not be able to be prevented. From this point of view, the incidence of fires in new homes is lower.
2.Assuming that the room has been more than five years, then the circuit breaker may fail, the aging of the wire may not reach the rated load and the insulating skin can not be well flame retardant, so the probability of fire in the room at this time is greatly increased, it is recommended to replace the circuit breaker, or if you have money, then redecorate and replace the wire, remember to wear the pipe.

Consider installing additional fittings to conceal wire threads. The ceiling is for aesthetics, and the second is to hide the wires through the pipe. Not all wires need to be lifted in old salt silos. Other accessories are available. >>>More
If you have to standardize, then wear the pipe, try to replace the wire with the joint (now basically do the live wire), if you really can't replace, the standard approach should be installed junction box, if it is simple and need insurance, wrap the copper core with a soldering iron tin, and then wrap the ...... with waterproof insulating tape >>>More
Ceiling through the pipe, to group control to wear more control line, zero line, grounding wire can share the downlight at the streamline head, and so on the ceiling construction is completed, according to the size of the downlight hole, connect the power cord, turn on the light to try, there is no problem to install the clamp on the lampshade, stuck on the ceiling. >>>More
Yes, the grille lamp needs to be equipped with a grounding wire. The reason is that the light box is metal, and any metal lamp must be protected by a ground wire. It is the staff who are protected.
There is no bolt hole in the head of the PE pipe flange, generally a steel casing flange with a large inner diameter is sleeved on it, and the PE pipe flange is pressed with the casing flange and connected with other flanges!
