Our Whirlpool GJC3034R Cooktop needs to be replaced so while doing the research I realized that it is rated 40A (here is the excerpt from the manual):
A 4-wire or 3-wire, single phase, 240 volt, 60 Hz., AC only electrical supply is required on a separate, 40-amp circuit, fused on both sides of the line.
but when I checked the panel I noticed it was installed on double 30A breaker and was operational for last 8 years like that.
I'm about to purchase a replacement but that one is also rated as 40A.
Anyway, is it okay to install a 40A appliance on a double 30A breaker and am I correct in thinking that the worst thing that can happen is a tripped breaker if we try using all four elements simultaneously?
EDIT
As suggested by someone in the comments section I checked the element wattage of the Maytag MEC7430BB which I intend to purchase and it was 8600 Watts combined. Converted to amps that is 35.83 so again, as long as we don't use all 4 elements simultaneously the strength of the current will be below 30A and all should be fine, other than the possibility of a tripped breaker,... or it also depends on the gauge of the wire?
