Chasing out

[PeterPan27]

Just i simple question peeps.

When chasing out a wall to fit 1.5 twin and earth how far do you have to chase? 50/65mm? Also you cant just plaster over the cable cause thermal insulation.. whats the plastic cover called? which you place over the cable then to plaster/fill over?? and is this tacked into place with small nails?

Sorry if its a stupid question. so far all my work has been done on metre square boards lol

Capping is only used to protect the cables from the plasterers trowel, if you need to protect the cable then use Metal Conduit, JMO.

I use SWA as standard on every job, even for door bells. Can never be too careful IMO.

I always uprate the SWA too, just in case they decide to add a super dooper 50kW doorbell in future... It's a bitch trying to make off those 16mm cores in the bell housing though...

That's where you've gone wrong my friend, don't use bell housing, i tend to install a three phase air horn where permissible, really let the neighborhood know you have guests.

I just knock on the door. no capping no cable, and i comply with all the regs. Very old fashioned method ,i must admit, but it works.

Come on! What is there to hate about knackered knees, lungs full of plaster dust, decomposing rats under the floorboards and carpets soaked in dog pee?!

in the building regs there are depths to adhear to for vertical & horizontal chases.

Only maximum depths for chases, to avoid compromising the structural strength of the wall. There's no minimum depth for cables.

Did the OP mention chasing out to 65mm depth? That's 2.6 inches! Jesus, if you do a horizontal chase you'd be sawing the top of the house off. Daz

The new cables would hold that roof up no problem lol


I think people must get the excavation bug and seem to be prepared to destroy the house for a piece of cable

I think some people see the 50mm depth rule for rcds and assume they need to go that deep. Daz

Vertical & Horizontal.. Thats no good to me.. Im purly a diagnal man myself.. Less cable you see..

Why even bother burying them, just lay them under the carpet and put a well placed coffee over the top.
