32A circuit feeding hob and oven

keylevel

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:

  1. 10A + 0.3 * 20A = 16A for the cooker
  2. 8.25A for the oven.

Which would appear to be ok on a 32A circuit.

    If it was my own I wouldn't worry about it . If it was for a customer I would recommend a 20 amp circuit  for the oven in case they have an issue at Christmas when they may use it all .

    Thanks, glad to hear as it would be a right pain to get a new cable run in!

    I've been living here for nearly 10 years with it as it is, do a lot of cooking, and haven't had any issues with the current setup.
