Wires buried in plaster vs oval conduit

[Pete999]

Our electrician was very happy to find that a switch was wired via oval tube when changing the switch to a two way. He had no trouble pulling the new cable through.

I have also pulled new cables through several times in previous properties without any problem when I have made my own wiring changes (before the new rules came in). Perhaps I have been lucky!

You might get away with it on a light switch drop with one cable in the tube, but more than one???

What new rule is that then

No it is great for lighting cables and these are the ones you are most likely to withdraw.

It seems the way of things these days,I personally would sheath/capping the cabling,its quicker & looks good

had many a happy day threading new cables through the old oval metal tube used circa 1950's / 60's down to light switches. several times has customer happy as a dog with 2 d*cks, saying " how you got cable down there without chasing?" not so easy with the longer drops for sockets though, but usually positional changes mean chasing is necessary anyway.

I personally don't see the need for it.
Chase's are protected from the trowel by there narrow width. I like to bond the chases myself prior to plastering.
Most block work is drylined now days.
If it was to be floated and set only then would I employ capping

I have never seen plaster laid directly onto block work, its usually laid on top of dot and dab/plaster board. So the need for capping is non existent and unnecessary, trying to add or modify a circuit with capping makes more mess then if it was clipped to the block. As for the oval conduit it seems like a novel idea but not a definitive method, horses for courses and all that.

Anyone remember using split metallic oval tube where you put a rubber bush on each end? Kids today eh?

@Pete999

Cant say i can im afraid i guess it got phased out with mullets and transistor radio's. I used an SDS on my first day, says it all really
