no sorry, I meant to say green to earth, red to phase, blue to neutral. Used this on other installations and it's fine.. More I think about it the more I'm kicking myself as 0.03 is no way correct, but I did see the reading on his meter... DNO Guy said that since Part P call out for high Ze...

I was there, even made him disconnect the main bonding to make sure that wasn't pulling the reading down. I'm thinking this Fluke is [rubbish].

I need some advice as the following has got me puzzled. TN-S system I measured Ze got 8.96ohms DNO came out and measured it and they got 0.03ohms!!! I'm using a Fluke 1652: Switch off the main swith in the CU, Disconnected the earth, Select the EFL test, and L-PE, zero the leads...

Nope, I rang them on a Monday(9am) and told them I would be in Mon, Tue and Wed. I was house bound for all three days..

Yep, people living there... It's at my house!! funny how you tend to forget the things closest to you!!!

The insurance is a good idea. DNO is EDF, there seemed pretty good on the phone, but it's getting them out (at a mutual time). Not sure why they are not too bothered about a Ze that high.

Oh forgot to ask. anyone know how to get the DNO out, been waiting 2 weeks for them to come and sort out a Ze of 20ohms (TN-S). Keep phoning but no luck, initially they said within 24 hrs!!!

Yep that's what I thought. It's down to the fact that you pay for the use of their forms. I spose it is a way of showing a customer than you are competant.

Hi all, I need some legal clarification... Part P covers installations, so you pay your money, have an assessment, join and are able to self certify your work and basically miss out the Local authority building inspector. Quite clear to me. With Test and inspection (periodics) Part P...

Hope you can help Just need clarification about supplementry bonding in kitchens. From what I've read this need was removed in the 15th edition WR. However when I've worked at commercial sites (mainly offices) supplementy bonding is always in place in kithens and even at small tea...

Thanks Guy's

Hi, does anyone know what changes/amendments are going to be in the 17th wiring regulations? Is there a site where i can get a sneak preview? Thanks

Ok understood. Have the DNO coming out anyway as beforehand I did a few tests and Ze was 20.4 ohms (TN-S). So they can do two jobs, maybe for the price of one!!!!

Hello to all, Some advice would good be as I've just started out after years of sitting behind a desk.(I was in Electrical Engineering not Insurance before anyone asks!!) If you change a consumer unit and there is not a suppliers cut-out is it ok legally to cut the crimp wire and pull the...
