OK. Will soon be in a position to get a spark in to test my complete rewire (grand prix delayed me a little yesterday). How should I leave the new system? (i.e. all connection up to MCB's meter tails at the ready, with all face plates connected and secured?). Also are there any tests I can perform myself prior to getting the spark out? I take it i can perform continuity tests using my meter...
Regarding your preliminary no-power testing: A moving-coil meter is preferable, but not essential for this testing. Using resistance you can test the ring loop resistance just to check its in the right region, typically below 2ohms (if your meter will measure this). Checking continuity also enables you do deduce you have the L, N & E wires going to the correct socket terminals (a sort of polarity test). Similarly you could make some basic continuity checks to various light fittings, and check the switches operate the right way up etc. Personally I think simply double checking you have the correct idendification labels on the various MCB's is important, that's the sort of silly error that could waste extra time for an elevtrician.
Unless you know what you are doing, you'll just be wasting time. The sparks has to put HIS name on the cert, so he'll have to test everything himself in any case. He won't take your word that you've already tested this or that and its ok. Nothing wrong with testing for any silly mistakes before hand but don't be under the impression that you'll be saving time and money by testing yourself. TT
Hello J I should go along with TT's advice,but it would not hurt to do a visual check again of all your work (the sparks will do this before he starts testing)some of the commonn things picked up on a PiT are, 1.No grommets on your metal back boxes, 2.No CPC fly lead to the terminal in the back box. 3.Adequate markings on your switch wires (red Sleeving) 4.Sheathing of your cables INSIDE your back boxes 5.All circuits labelled on Consumer unit. 6.No loose connections/pinched insulation at terminals.... The list is quite exhaustive........ Anyone else up for any more? SF
sorry sifi, Exhaustive means it will run out! I mean the list will not run out...Not Exhaustive I am always amazed, but never surprised at what you can find during a PIR report

No props, its usually me with the grammer..bottle of red wine......i think i have a glass and a bit to go until the bottles empty
Just a quickie Lec, Now its become evident your (sshh ) NIC I have just completed my pre-assesment and was wondering when the BIG assesment gets about is there much to do on the day? Please dont tell RR I have done this,as I now how much he likes the master race.......LOL SF (jlp1968@hotmail.com)
I joined the company when it was already registered. When i became supervisor at our company, i had a half day of my work being looked at, and many technical questions asked. They are generally ok, they will always pull you for something minor, but thats their job Good luck with your assessment.
Thanks Lec for the Info, Its appreciated. My pre-assesment was ok,got asked a couple of nasty questions like, Whats the Max continuity resistance reading for main bonding..you should have seen my face,wish I had me polaroid! Sf Does anyone know how I can get a piccy put on here,maybe its one for the IT boys?
If you connect the mains before carring out insulation resistance, R1 + R2, you have failed a test cert. SORRY.........

HI SI Take a look at page 79 GN3 (should be in the ORDER of...) si keep the 17/18 of JUNE free wot was the other Q
Hi chubs, I was told of the answer .05 ohms (which I have and will not forget) Whats happening 17th 18th June? S jlp1968@hotmail.com
