How to prevent fire in the second house renovation

Many old houses should consider replacing the main power box in the interior during the second renovation, because the original power box is generally not loaded enough and no leakage protection device is installed.

In addition, in old residential buildings, the original socket circuit may not have a grounding wire (usually only two holes of the socket are missing grounding), which does not meet the electrical safety standards and must be replaced. One method is to replace the main power box of the house and set the grounding in the power box. Another method is to consult the power management personnel of the property to negotiate the installation location and connection method of the ground wire. Do not make a claim to set the ground wire.

The transformation of the electric circuit into the electric power line of the plastic copper line is generally called strong electricity, and there are mainly two parts of the lighting and the socket circuit; in the second decoration, the transformation of the circuit is necessary for each house. If the original residential circuit uses aluminum wire, it must be replaced with a plastic copper wire. Because the aluminum wire has a low melting point and large electrical resistance, there is a potential safety hazard and the country has explicitly eliminated it. Before the renovation, several socket boxes should be opened to check the nozzles of the originally installed wire tubes. If the wire tubes are rusted, the original wire tubes cannot be used and they should be discarded. If the wire tube is well-preserved, the wires in the tube can be replaced directly. If the tube is threaded with a plastic wire that meets the standard, it can still be used.

In order to save renovation costs, the original lines can be used without removing them, but the newly added power sockets and lighting circuits are preferably routed separately from the distribution box, and do not directly connect directly from the original circuit or directly from the outlet. Leads, because all the original circuit is installed, the current is calculated and distributed according to the load of each circuit branch. Any connection or addition of sockets and lighting fixtures to the original circuit will cause the overload of a single circuit, which is likely to cause Tripping or burning of the power mains can cause serious fires.

In the second renovation, the transformation of hydropower and other lines is a particularly important project, and almost every family will be involved. In particular, some old houses, if they do not change hydropower, can no longer be used normally or are prone to fire, running water and other dangers. Well, in such an important transformation process. This article is provided by China Rescue Equipment Network.
