Discuss Drilled through 30am cable powering oven and hob in the Electrical Forum area at ElectriciansForums.net

Welcome to ElectriciansForums.net - The American Electrical Advice Forum

So... a bit of a faux pas happened the weekend... i managed to drill through the 30amp mains cable that goes down to the oven and hob.

Anyone know the best course of action short of channelling the wall out and rewiring the whole thing?

Kind regards

Hi Dan and welcome to the Forum.
Usually Kev the kitchen fitter that gets the drilling accuracy award, ha ha. Anyway, most Electricians can repair this type of thing and test to ensure it meets safety specs afterwards. Someone on here may be local and able to pop by if you want help with it.

Is it the section of cable in between the switch and hob/oven or is the cable just going straight to the hob with no switch?
You might get lucky and be able to tie on to the old cable or if there is no switch that could be an ideal location to install one

Presumably the drilling was to put up another or replacement wall unit or shelf. I would install a surface 32A jointbox, I’ve used a surface white 2 gang back box & blank lid with Wago connectors or similar, in the back of unit. Then replaced the ongoing cable with new. If it’s a shelf, you’ll need a suitably placed cook book. :)

Hi All,

Thank you for the replies. I have attached more images of the cupboard and also the wall... I assumed the cable would run central to the plug so i drilled either side of it. The man who previously owned the house did all this himself by the looks of it and never put any sheathing around the cables and has plastered them straight into the wall.. which is a pain.

This is what the father in law suggested and he said he can do it but wondering whether it will need signing off or certification? I think the bloke has put the hob and cooker on the same mains cable.. so would it work to put the switch in, change the cable below that, remove the old switch.. put a 3way junction box in and then split the power to hob and cooker? we are planning to get the kitchen done over the next few years so we potentially will put some conduit down the other side of the wall and back into the cupboard rather than taking all of the tiles down and potentially the floor up to get into that cupboard.

For future reference, stay outside the horizontal and vertical edges of accessories and start off with your drill slow with no hammer action..

also bear in mind that the cables are within 6" of the wall corner. this is a prescribed zone.( all blue areas).

looking at your latest pics. i stand by my previous advice. a MWC ( minor works cert. ) should be completed. notification to BC is not required. move the isolator/socket up to above the damage then rewire to outlet. careful removal of a tile or 2 and they can be refixed after.
