Could you elaborate? Are you thinking of the thermal heating element of touching the insulation?No - it may reduce the current carrying capacity of the cable
I don't know if you're an electrician or not but I'm talking about the effect insulation has on cables. Some brief information here TLC Electrical Supplies - https://www.tlc-direct.co.uk/Book/4.3.6.htm
I have an local electrician who has agreed to sign off. He will monitor the work throughout. Just wanted to get everything right first time, know as much as possible and make sure the installation goes smoothly.How are you going test and certify this installation?
Fair enough. Is he involved already to advise on cable sizes and routes though?
Nice thought, guess ill be paying for the high quality finish. Would still need some conduit to run the cable through the insulation? Or do I just use the de-rating factor in calcs? Or Both!!?You could try these, not used them my self but may leave a better finish. The problem with the plastic dry lining boxes is that they bring the edge of accessory out a tinny bit from the wall from which may be a problem if you are looking for a high standard of finish or fitting flat plate accessories .
