how to test a socket?
- Thread starter magico
- Start date
it's a good start but if the block shows no earth then get a sparks to rectify immediately as you will only electricute yourself once and that will probably be final.
How do you define testing a socket?
A plug in Martindale style socket tester will test for correct connection though it won't indicate neutral and CPC reversal.
It also won't alert you to the fact that earth fault loop impedance may be too high to allow disconnection within 0.4s or cables feeding the socket have an insulation resistance greater than 0.5Mohm.
You'll need specialist equipment to perform tests on the circuit feeding the socket in question.

He may be a mate but he sure as hell isn't an electrician. No electrician would leave a CPC disconnected because he was in a rush. Call someone competent in and tell your friend that if he is trading as an electrician then he might want to consider retiring before his negligence kills someone and he ends up in deep sh1t.magico said:
i have had an electrician round,he fitted a new consumer unit for me,so all sockets are rcd protected now,and got him to do a periodical.
thats when he tested the sockets in question and said theres no earth to them.he said its probably not been crimped properly. he only tested it with a plug in tester i`m sure. also found another socket in house which had live and nuetral mixed.
so if i use a plug in tester and check whether its a loose crimp and crimp again?

When did you get this electrician to change the CU and why the hell did he leave without fixing the problem?!
The fact he plugged his tester into a socket doesn't really narrow things down much - most professional multi-function testers have a socket adaptor with them. If you mean something like this then no, that will not show you/him anything useful and shouldn't be relied upon for any form of professional testing.
If you have a poorly crimped joint then cut back to fresh cable and use a new butt crimp. Remember to use a good quality ratchet crimper like this and to use the correct size butt crimp. For 2.5mm² t&e you need a blue crimp for the live + neutral and a red butt crimp for the CPC.

Changing the CU requires notification sent to the council, certificates of Electrical installation, testing the total installation (all circuits) and leave you with the original certificates signed by the installer that must be a competent person.
Any of this was done?
I use very often one of this socket testers, for missing earth, reversed earth /neutral with live etc. But this is only for very basic checks, and I do not use it when I do an installation or PIR for this purpose I have all the tools/meters required by the regs.
