If I have learnt anything in renovations, its not to trust the color of the wire. Just because that isolator has a black and a red wire, does not mean it is a live and neutral. It could be used to switch the circuit in an attempt to use only 1 conduit and 1 strand of cable.
Good to know. Thank you! This switch is on its own circuit with nothing else sharing this circuit. I checked at the DB board last time I was there. I'm still leaning towards my theory that this electrician was lazy, realized there was no oven at the time and took a chance with the family member not knowing any better.
That's bad. Chop and retile do it right.....
I agree. The family member does not currently have the finances to do this and buy the oven. I'm a terrible tiler and definitely won't be attempting this (especially against a vertical wall) but I know someone who owes me a favour and might be willing to help her out at a discounted rate.
Thanks for the advice and input everyone.
