Spot lights cables

[Moggaman]

Hi. The guy fixing my plasterboard has put plasterboard over the locations where the spots are but where pendants are , he has dropped those cables thru the plasterboard???

Is it up to the electrican to know where to drill for these spots when 2nd fixing?

thanks

Also, I see the electricians use this metal banding to tie things down. I  can’t find it online ..what is it called, and how do they fix it the concrete…. Rawl plug?

thanks

Lets hope the electrician (or you) remember exactly where the cables are, and hope the boarder did not move any of them.

Yes raw plug or concrete screws are very useful.

 

You should always take loads of photos and when you think you've enough take some more. Useful for occasions like this.

The electrician should check to avoid drilling into joists when planning exactly where the spots will go. If he has any sense he will have taken photos or marked a plan previously.

 

When he drills the plasterboard it doesn't usually damage the wire because the wire moves offering no resistance. That and a bit if care is usually sufficient. Then he reaches through the hole to find the wire.

That plan falls apart when the plasterboard installer moves those pesky wires out of the way so when you drill the holes, there are no wires within fishing distance of your holes.  See post 4
