My cooktop keeps blowing its screw-in fuses. I think I've got the problem figured out, but I thought I'd check to see if anyone here can see a problem I'm missing...
My cooktop appears to have replaced an older model (replaced by previous home owner), and the fuse box for the cooktop has spots for 4 fuses, but when I open it up, I see that only 2 are actually connected to the appliance.
It appears that the current cooktop uses a 240V 3 - wire connection (two hots, no neutral, and a ground), and that's what's coming from the panel. The fusebox has labels indicating that the two fuses (each of the hot lines are fused) that actually connect to the cooktop should be 15 Amps. That's what was in the box, and that's what keeps blowing.
I think that the sticker is wrong - that it must indicate the amperage for the old cooktop for the small burners or something.
The current cooktop has a rated peak load of 6.1kW, so with 240V service, this would indicate that it needs ~25.5 Amps to supply that load, hence the blown fuses.
So I think that I should be okay to just replace these 15 Amp fuses with 30 Amp fuses and carry on - and remove the stupid misleading sticker.
I'm no electrician and I'm afraid I know just enough to be dangerous. Does anyone know anything about this kind of electrical? Is there something that I'm missing? Because the circuit is supplied by ganged 40 amp breakers, should I be able to assume that the wire is good for 30 Amps?
