For the handover test of low voltage electrical equipment, the insulation resistance of the motor, the distribution equipment and the distribution line shall not be lower than 0.5M at ambient temperature (for the running equipment and circuit, the insulation resistance shall not be lower than 1M /kV).

Q:Know the power tool type and how to find the corresponding carbon brush: Because most electric tool is the copy of foreign or domestic large and well-known brand products, such as Japan's MAKITA 4100 stone cutting machine with 303 carbon brush, Zhejiang 100 angle grinder with 51 carbon brush, 26 hammer with 21 brushes, just look for is the imitation of the machine, with the original machine manufacturers to see there is a Book brush type in the above, a model to sell electric tool shop, or ask sell electric tools, all know, remember do not buy too cheap, cheap ordinary machine if you just, if imported or domestic good machine, or more than 1000 watts of power to machine.

Q:What are the motors that are often used in hand held electric tools?: Considerations for hand held electric tools:Before the tool is used, the electrician shall check whether the wiring is correct and prevent the connection of the zero line and the phase line.Tools that are left unused or wetted for a long time should be checked by electrical engineer before use. Does the insulation resistance meet the requirements?.The soft cable or cord that comes with the tool can not be connected long, and when the power is away from the work place, it should be solved by mobile electric box.The original plug of the utility model can not be dismantled or changed at will, and the metal wire of the electric wire is directly inserted into the socket without using the plug.Found the tool case, handle broken, should stop using, replace.Non - professional personnel shall not disassemble or repair tools without authorization.The rotating parts of hand tools should be protected;Operators are required to wear insulation protection products;Leakage protector must be installed at the power supply.
