Hi guys, Iv'e just qualified as a sparky and I'm going to rewire my friends house that he is renovating. I'm wondering if someone could clear up a couple of questions please.

1. The supply is a TT system with a earth rod out the back, the previous owner had a boiler fitted so the earthing was upgraded. The electrician has run 2 x 16mm earth cables up to the C/U. one goes direct to the earth rod and the other runs from the gas meter.The earth rod is right next to the gas meter so I thought I could go from the gas meter to the earth rod and to the C/U. Is this correct or does it need to go all the way to the C/U.Well in theory it doesn't matter where the MET is, so yes the rod could be your MET. In which case the conductor to the cu is fine as is the conductor to the gas meter ........?


2. Checking the on site guide it shows cable run's up the corner of wall's, along the top of the wall's and horizontally at 150mm, but can I run the cable along the bottom of the wall's, behind the skirting as the house is concrete floors. A non starter ..................sorry!

3. Just to confirm I have bought a BG split C/U with twin 30ma RCD's, This will be OK on the TT system..?? won't it. Yes if installed right it will be fine
going to cross bond all the boiler pipes and bathroom pipes.Read the regs .............it might not be required:wink_smile:

Any info would be great as I'm still learing. You missed the N in learning....we are all still learning so ignore the pontificating individuals!

Regards

Steven
