any electrical engineers out there...

Hi,, my Uni days are getting a bit distant. trying to estimate the power factor of a domestic electric oven and hob. (SWMBO wants posh new hob and oven to run from 8KVA generator) I think they are mostly resistive so PF should be nearly 1 - or have I forgotten to much...

You memory is better than you think for basic resistive oven and hob.

Even if it is an induction hob it should already have built in power factor correction if it was designed for domestic use.

Yup your memory is fine. For a pure resistive load, PF=1. You got loads of capacity with 8kva genset

Mikehibb, i don't know for sure but as a wildish guess I'd think an induction hob isn't actually an inductive load on the supply line. Dunno, happy to be corrected on that, but the induction is to do with agitating the metal in the base of the saucepan, which might not be an inductive load in the way an electric motor is

An inductive hob is meant to not get hot but to work requires heavy pans, cast iron or the like, for the cooking. You are correct in your surmise.
