Chasing out?

[dez0178]

Hi,
I am currently half way through my second Year at college studding C & G 2330. I am trying to get into the trade via Electricians mate, but no luck yet in doing so. I would like to know when chasing out a channel for either ring or lighting cable, should you remove the plaster until down to the brick, what is an acceptable or the correct depth?

Some good points and advice cheers!

Most plasterers won't want a nice neat line anyway. A more ragged channel makes for a better bond with the new plaster.
And can totally second what others have said. Don't use a grinder/cutting disc. ! Unless you have dust extraction. !!!
Nice big wide chisel and a hammer. Bosh....

Why Different depths for Vertical and Horizontal. P.s You Folks on here are great for helping out, read a load of threads on here, some really good stuff.

its a guide so as to not affect the structural integrity of the wall mate, yes its a great site helped me a lot

I'd recommend you get a copy of "The Electricians Guide to the Building Regulations" - it costs about the same as the OSG and is full of useful information.

Thank god I stayed in heavy engineering, houses would be a pile of rubble if I set to.

I tend to stitch drill down the chase first then knock it out with a comb chisel or cold chisel.
