Running in a new CPC

[marcuswareham]

Hi guys

I was putting in a spur socket at a friend's house. when i noticed that the CPC is the metal cable trunking. I understand this is within regulations. However upon testing it had a high earth loop impedance and likewise r2.

My question is, is it acceptable to run in a new CPC from consumer unit MET to the relevant outlets, but using a different cable route (plastic trunking etc)

Thanks Marcus

Have you tried tightening the conduit termination at the board.

Have you tried tightening the conduit termination at the board.

Yes indeed, and checked earth bond

So after a lot of swearing I managed to get a new CPC down the conduit, draw tape was not much use and there was loads of brick, concrete and plaster that had fallen down conduit over the years. As the immersion heater is soon to be no longer needed due to combi boiler going in I used the neutral conductor for it to pull though the CPC, all good now

Also found out the light switches are earthed via conduit, just the one I picked to look at the conduit was not attached to the back box haha

Thanks for you guys help and suggestions
