Thanks for the reply!
As far as I know it’s all the original wiring from when the house was built around 1985.?
will have to get the extractor checked then, when I switch that big red rocker switch it turns the hood off..
as for retro fitting the breakers, those that you linked to will fit, are they a universal fitting? And presume the numbers on the front are the amp rating?
The top cover could be cut to fit the new breakers couldn’t it?
Thanks, Rich.
