Success! Meter fitted.

[Percyprod]

Just like to thank everyone for their help and advice re by previous post, but contrary to some opinions, man from supplier came to fit meter this morning, and of course it is fitted and all working. He tested it thoroughly (checked polarity with a neon tester at isolator) and fitted the meter. Asked him if he wanted to see wiring certificate and reply was "No, not for a stable". I kid you not! Just as an aside, horses are still alive, but before I retired I was sometimes given a job to connect a rewire, usually after a cut-out change or a service alteration. Companies rules were 'as you are not part p registered you cannot test the installation, so no certificate, no connection'. So if I'd been given this job when I was working I wouldn't have connected it! It's a funny old world. That was before I knew it didn't come under part p, but no more on that please!
Forgot photo of meter etc

Point taken about cu. I've got a plastic bodied one actually, that I was going to use but thought I would treat myself to a new one! I will swap it over. I also have a different clamp, with a bolt on one side, made of brass , will be a lot more substantial. Getting a ze of 46ohms.

Meter tails not harmonised, meter load tails stretched, not the best meter install.
I never connect customer tails into the load side of the isolator on a new install, ensure the isolator switch has a plastic lockout seal fitted same as the load terminal cover and the required warning notice is screwed to the back board.
