Electrical outlets are present in each apartment. To them connect all appliances used in the home. If the first were enough pairs of sockets on the room, but now there are more. Respectively, more likely to be a situation where one or the other outlet is faulty.
When the appliance is turned on it nothing happens. The reasons for this may be different. What to do in such cases?
Why there is no voltage in the power outlet?
The situation when a plugged-in appliance does not work, can occur for two reasons:
- off in the switchboard of the circuit breaker, which is powered by this outlet;
- open phase or neutral conductor.
Make sure that the problem is in itself an outlet, you can use a screwdriver indicator. To do this, it turns to touch both the socket contacts. If it contains a voltage, the touch of the phase conductor will cause a glow-indicator light bulb placed in the handle of a screwdriver transparent. If this does not happen, then the socket is de-energized or defective.
You can also use a multimeter. For this purpose it is necessary to select the metering mode AC voltage. Then, both probe is inserted into the outlet openings. The screen should display the mains voltage, if the electrical outlet is working. Otherwise it will be zero.
Finding that does not work one of the outlets in the room, you should review all available in the apartment. This will help determine whether the problem is sporadic or no power on all sockets.
Not all the sockets in the apartment
This can happen in the following cases:
- the local power supply is temporarily cut off power supply, for example, because of an accident at the power lines;
- knocked induction machine in home electric switchboard.
If the switchboard sockets each room connected to a separate machine, it is possible to shut down the only one. It is easy to determine if the other rooms with rosettes no problems, as well as the lighting is functioning normally.
Just turn on the specified circuit breaker, so that the rosettes reappeared voltage. But first you should find out the reason why there machine operation. Probably, the reason served simultaneous operation of several major power consumers. In the worst case, somewhere along the line there short circuit. It will certainly need to be addressed, otherwise the consequences could be very unpleasant.
It does not work only a few sockets
If you do not operate a specific group of outlets, you should check the status of the circuit breaker, by which they are powered. If you turn it on it works again, it is necessary to eliminate the short-circuit wiring.
When not working, only one of the outlets, the probable cause is the absence of one of its contacts. Either there was a wire break or just a weak one from the socket contacts. To remedy faults in the state, anyone with skills in electrical wiring. But it is better to entrust the work of an experienced electrician.
If no problems were found during the inspection socket, check the connection of wires in distribution boxes if available.
