How to get cable through an insulated cavity

[Richard Bates]

Does anyone have the faintest idea how to do this? My old house has solid internal walls and the cavities have been insulated. My electrician was going to run a new 10 sq mm cable through the cavity to supply my new electric shower. How are you going to get it past the cavity insulation I asked. "Oh cripes, I have never done that before.", came the reply. I can't think of an easy way to do it either can you? Rich Bates

Drill a hole through it - isn't it just foam?

Or do you mean down the cavity?

Well it's not good practice to run cables through an insulated cavity, so I would look for another route and leave the cavity alone.

Well he will have to derate the cable if he runs it down the cavity through the insulation, for a start.
