I've recently installed a stud wall and extended the existing wiring for two double sockets by using a block connector and single cable. Does anyone know why one socket would show 240v and the other show 208v please?
Thanks.
What is the voltage between L and earth on the "208V socket"?With a multimeter. .... The 240v socket does, the 208v socket doesn't. {work}
Thanks. That strongly suggests that plugwash was right, and that there is a loose/poor connection on the NEUTRAL at that socket.Thanks John. It's 241v
I agree with your conclusion (as I said, it sounds like a poor connection of the neutral at the one socket).Sounds like you have a bad connection - it's got a high, but not "infinite", resistance. So when testing with your high impedance voltmeter, you get a reading, but as soon as you apply a load, all the voltage disappears across the high resistance joint. This is the reason why we do certain tests to check work, using equipment that puts a reasonable amount of current through a circuit.
That's not my understand - which is that one was reading 240V L-N (and 'working') and the other reading 208V L-N (and 'not working) but (following my question) the latter reading 240 L-E ...My guess one reading line - neutral the other reading line - earth, lets see if right.
