Picture of the week!™

Well folks, it's that time of the week again!

This week we have a plumber who didn't know how to set the depth stop on his circular saw.

Yup, 3 cables damaged in one go

Is that charring from the short circuit, or was the blade blunt??

I think it was from the short.

The cable sheaths were fairly well charred too.

BS3036 fuses, so it may have been fizzing for a bit

How did you go about repairing that?

I would if I could replace each section of cable if this was not possible I would go with crimps heatshrink but this also introduces a second problem. If there is not enough slack you would end up crimping in extra cable to overcome this. Crimps been maintatence free would be the ideal solution. I would not use a junction box. I would prefer not to joint if the cables were accessable enough to replace.

How did you fix it RF?

I'm struggling here... I know it was common 50 years ago to put cables immediately under floorboards. But surely not currently allowed. So I wonder if the plumber quip is that smart. Surely an electrician put cables in a dubious location.

As a matter of interest, was this allowed then?

Looking at the staining on plaster board I wonder if he'd hit water pipe at sometime

Looking at the blade marks on the floor board I would guess it was protruding by at least a good inch

I'm not sure I understand your statement. Notching on joists is still allowed and that tends to encourage the cable to rest nearer the surface (underside) of the floor boards.
Good practice encourages protection plates on the joist to prevent floorboard nail damage.

How could an electrician ever account for the prospect of a trade guy opening up a floor with the saw set beyond a 22-25mm stop depth ?

 

[BS3036]

It's probably just a misapprehension on my part. Everyone, including many DIYers, is familar with safe zone diagrams for walls.

Are you saying then that the whole of the floor and ceiling are great big safe zones? Or do the normal rules relating to 50mm from surface apply?

(This is a serious question)
