A number of the sockets in the flat are temperamental; i.e. the connection is inconsistent when you put a plug in and power can fail to the appliance. It has also caused an issue for correct functioning of the powerline ethernet adapters I have.
I had an electrician in a while ago to check them and expected he would replace them all. In then end he checked a few sockets, said he had found the one faulty one and only replaced that. But the issue still persists. Not convinced I had the right electrician, but there you go. So I thought I would try to do some initial testing myself.
I have since acquired one of the plug in socket testers and this appears to have identified quite a few sockets with a poor connection - i.e. if you wiggle the tester slightly it restarts the testing sequence. At the same time it appears to be highlighting other issues. Are these things I need to be concerned about?
The tester is a Kewtech Loopcheck 107.
Wiring = 3 green lights + continuous tone (wiring correct)
Loop test = amber (1.8 to 92 ohms)
RCD check: pressing and holding the RCD check button does not trigger switch off at the consumer unit. Looking at the consumer unit there doesn't actually appear to be an RCD (see photo).
I know some of the socket front plates need replacing, but might I have more of a problem?
