Hi Guys
As a regular electrician, may I please lay some myths about cable capping.
1. Cable Capping is not designed to protect against nails, but to protect the cable from the plasterer's trowel on traditional plastered walls and particularly aggressive lime based plasters.
Neither the steel version nor the plastic (which I will occasionally use) will protect against nails.
In fact, only steel conduit, steel trunking or SWA (steel wire armoured) cable are considered by BS7671 (The Electrical Regs)to offer adequate mechanical protection against nails and such like.
2. Where walls are being dabbed (or battened) and boarded on top of the cable it follows that capping is not required - I put in a enough clips to keep the cable straight and supported.
3. If I'm doing a rewire I'll cut a chase no wider than the cable and make sure it's clipped down below the surface - less work for the plasterer and less for me and less mess for the householder.
Has anyone got any problems with this?
Cheers
Pete (p'd off because on latest batten and board job, plasterer first complained about the lack of capping and then managed to put a nail straight through an armoured cable! Point made! Using a nail gun I think.)
