Two quickies...
- I am shortly to rewire my upstairs lighting, (the wiring is in the loft). When new loft insulation is shortly added the cable will be buried under the insulation, but I am not clear whether the regs require that the cable needs fixing to the joists, or can just be laid loose along the ceiling, (as the current wiring is). [NB. We have already discussed the cable derating implications in another thread].
- In replacing the wiring to the light switches, I intend to use the existing cable to pull through the new stuff, (it is in oval conduit). Has anyone got any tips for how to mechanically connect the two cables, obviously with the smallest possible cross section to enable the joint to pass through the conduit. Is insulating tape generally strong enough ??
