My hob needs replacing and I've been looking at getting an induction one rated at 7kW. Installation instructions say it needs a 32A circuit (which makes sense).
Looking at the existing install, I have an oven (~1.9kW, based on smart meter reading) and the existing hob (also 7kW) running from a shared 32A circuit.
Is this acceptable, or do I need to get the circuit upgraded?
Looking at an old copy (2004 / 16th Ed) of the OSG, the diversity calculation seems to be:
- 10A + 0.3 * 20A = 16A for the cooker
- 8.25A for the oven.
Which would appear to be ok on a 32A circuit.
