13 amp in what? The fuse/mcb should be a 32 amp.Hi guys, I have a hob and oven on the same circuit, when I put all the hob and oven on the 13amp fuse keeps blowing, the RCD dose not trip thoug?? what’s wrong?????
Yes I think you are right, both cooker and hob are wire to a 13amp spur switch!!! Having just checked out cooker switches on screwfix I’m now assuming the Muppet that wired this up used the wrong switch? Please correct me if I’m wrong?Do you mean you have a fused spur with a 13A fuse in it protecting a 2g socket ?

You're never going to be able run both an oven and a hob from a 13A spur - as you have discovered, if you switch both on at once (well over 13A total) the 13A fuse will blow. I presume that what you describe has always been the case whilst the appliances have been wired in this fashion?Yes I think you are right, both cooker and hob are wire to a 13amp spur switch!!!
Ok here’s a picture of consumer unit, oven written on breaker switch, the hob and oven are wired to a 13amp spur switch which is then wired to the consumer unit, this is all becoming clear to me now that maybe someone has used a 13amp spur instead of a cooker switch? so can I assume that it’s safe to replace this 13amp spur with both hob and oven wired to a suitable cooker switch?What circuit in your consumer unit is the fused connection unit a part of ? Can you show us some pics ( full consumer unit showing all circuit breakers)
Yes it is, flip it off and the oven and hob are off.Is the fused connection unit connected to that circuit marked " oven" ?
If you flip that breaker to off ,what no longer works in the premises ?
If, per terryplumb's question you can confirm that breaker labelled 'oven' is supplying the oven+hob, (via that 13A FCU ('fused switch') then yes..... this is all becoming clear to me now that maybe someone has used a 13amp spur instead of a cooker switch? so can I assume that it’s safe to replace this 13amp spur with both hob and oven wired to a suitable cooker switch?
If, as seems to be the case, the 13A FCU is fed by that B40 (labelled 'oven') then it appears to be RCD-protected ... but who knows what cable has been used for the circuit?Ps there are other things i have not mentioned RCDs and bonding for a start
