Chasing Brickwork for Cables

I'm afraid I don't follow...you mean you want to cut through the plaster, through the brick and have the chasing an inch or more deep? - what for?

almost all plaster is deep enough to hold a cable and a clip

I can't understand the fascination WRT trunking, I've never seen this used in domestic properties

Phil L coughed up some electrons that declared:

Possibility to rethread cable? Maybe not so important with mains, but *very* useful with ELV/comms drops, especially if you don't know what you want to put in them at first (or second) fix time :)

I've found that 16mm oval which is barely much thicker than T+E will take

BTW - I'm installing a perimeter roof run of 200x30mm + 100x60mm wire basket in my house - bet you've never seen that done ;->

Cheers

All houses I've done anything with have been initially wired with capping, and that's made rewiring very easy (only on one occation could I not pull though the new cable, or rather, pull out the old cable).

I almost always use oval trunking when chasing new runs.

You can get 12.5mm oval, which will take a triple and earth, and probably also a 2.5mm T&E. I also use for Cat 5e.

Ah, mice runs ;-)
