I want to swap a ceramic hob for another model. My current set is: oven and a hob rated at 2075+6000=8075W in total ,they go through a 32Amp Circuit breaker, the oven is plugged to the wall, the hob is hard wired. The new hob is 6500W, 2075+6500=8575W this should be fine considering circuit diversity. Is this a straight job (wire the new hob) or should I get an electrician to actually upgrade the circuit breaker?

  • 8575 watts at 220 volts is 38.9 amperes. More than a 32 amp breaker.

  • Not familiar with foreign codes, but the US NEC requires (in a footnote to a table, no less) that the amperage ratings of the hob and oven be summed and used as the branch-circuit load for the case where a single hob and up to 2 ovens are tapped from a single branch circuit.

Straight up. If you only work on the cooktop and do not go into the wall circuits, fair game.
