Hi,

We have just had our loft insulated by a professional firm, and in the loft they have left a checklist (which is not checked) which has a number of questions on it. One of the questions is something like "has all cabling of more than 5a been left uncovered?"

They have not left any of the cabling uncovered. The house was recently rewired (again, this was done professionally) and the lighting cables for all the upstairs rooms naturally pass over and between joists. Would these cables be less than 5a? If not, should I call the company which insulated the loft and take it up with them?

Thanks

Chris

I have no idea what "cabling of more than 5a " means. The only restriction that I am aware of is the any Knob & Tube wiring is not to be covered with insulation.

K&T wiring is the oldest wiring system, uses individual wires mounted on the porcelain knobs and passes through wood framing members using porcelain tubes.

If the wiring you have is Romex, BX, or MC cable, covering it with insulation is not a problem.

I'm in the UK, so perhaps the standards are different to US, but the cabling is new and was carried out to NICEIC standard and certificated as safe, so I guess that it should be one of the newer types that you refer to.

Since I can only speak for the USA code, if there is any question you should check with the insulation firm as to what they are allowed to do and not do, and check with the agency that certifies electrcial wiring. Now is the time to be sure there is no problem and not find out the hard way down the road.
