Installing induction cooktop as replacement

[Pablo]

Be sure you check that your wiring is adequate for the model you choose. Most coil/quartz are on 30A circuits. Many induction models require 40-42A.

I ran into that when choosing a replacement. I was deciding between induction and propane to replace a low end glass top electric. The wiring was 30A that would have had to be upgraded for the induction model I wanted. Alternatively I would have to have a branch for the propane installed. I opted for propane due to cost and the ability to cook when the power was out.

42A? That seems odd. Need a 50A breaker? Wowser.

We have a 40A, thank goodness.

A 40 amp circuit on 8 gauge wire for a range is code. 50 amp circuit on 6 gauge is better because more is gooder, bigger is better ect.

That wasn’t really the question or my point.

If the stove needs "42 amps" that means it should be on a 50 amp circuit, with 6 gauge wire. Not a 40 amp circuit running on a 50 amp breaker.

Of course but why did you repeat that ?

My question are these drop in induction cooktops really drawing 42 A?

 

[Pablo]

I searched around, there are a few commercial types that definitely would need a 50A circuit.

Most typical cooktops alone 40A.

But this could also imply a separate circuit for the oven perhaps, Unknown.

I wonder why the various amp requirements for different manufacturer's induction cooktops? Assuming one is comparing 30" cooktops for Must be higher power cooking elements.

Whether it's electric coils or induction it's takes close to the same number Kw to raise a gallon of water from 45F to boiling. OK the surrounding air gets a little heat but essentially all the heat goes into boiling the water.

Induction just does it quicker.

I have a 35 amp breaker for the electric coil cooktop.
So that would mean it's #8 and I can swap in a 40 amp breaker.

GE = 40 amp
KitchenAid= 30 amp

Every cooktop I replaced cutout was same. However if there are drawers under cooktop have had issues. Sometimes conduit for cooktop different location than original. Or screws on cooktop would hit drawers. And a cabinet maker would have to alter drawers.
