Warm tips: 1. Light bulbs are fragile, do not provide, please buy your own local do not provide light bulbs do not provide light bulbs do not provide light bulbs recommended to use 100W incandescent light bulbs (can not use energy-saving LED light bulbs) 2. This socket is not suitable for maintenance using inverter power supply.

Introduction to switching power supply service socket Maintenance induction cooker/TV/switching power supply or faulty electrical equipment in the process, such as the fault is not completely eliminated, replace the replacement of light damage replacement components, heavy further expand the fault scope, it is recommended to use the maintenance protection socket, such as load short circuit will prompt and protect the circuit from secondary failure.

Protective socket instructions Before power on, please switch (service switch) to (service position) and then connect the equipment to the socket. Switch on the main power supply to check the lamp status: 1. All on indicates a short circuit 2. No light or slight light indicates normal.

About empty open version  introduction The main function of this circuit breaker is equivalent to a switch, only under specific conditions will automatically disconnect (need to exceed the circuit breaker standard current, the incoming line should be thick, the incoming line fuse should be thick) Normal if the load is short, the fuse on the socket will be broken first, if there are other circuit breakers in the front end will jump. Therefore, this type of circuit breaker is not a short circuit protection in the real sense, so it is recommended that you must be placed in the maintenance position (that is, do not switch on the circuit breaker) for use.
