Induction hob plugged into standard 13amp socket

Glastoun

Hardwiring an induction hob would cost us a lot more in electrician time as we would need a dedicated circuit coming off the main board, but many hobs can be plugged directly into a standard 13 amp wall socket.

Does anybody run an induction hob in this way, and do you ever notice a lack of power? We never use 4 rings at once, rarely 3 at once and even then only 1 of those would ever be a full boil, the others on medium or a simmer.

Doesn't matter - the potential is there.

Do the job properly and there will be no risk - do the job badly and it's your funeral (in the nicest possible way ).

There are induction hobs out there that can be plugged in, i often see them in trade mags. Thats if you haven't already bought it, but as above if it needs a dedicated feed you have no choice. If its new the guarantee will be void, and house insurance if the worst happened.

You missed the point - the hobs are designed by the manufacturer to be used from a standard wall socket as well as hardwired into a dedicated circuit, and even come supplied with a 3-pin plug already attached. When the limit of the 13amp supply is reached, the rings share the power between them, I'm just trying to work out whether we would encounter that in normal use.

Were you picturing this?

The ones with the plugs on, will work ok via the plug. They just wont be as powerful as the hard wired ones. You will find a decrease in power to all four or three rings, if you are running them together.


Typical power rating for plug in 6.8kw
typical rating for wired hob 7.4kw+


If you are happy with this, fine, but you cant complain about things taking longer to cook, if you have accepted it. We have a wired in one, and it is great. Best thing invented for the kitchen, since the dishwasher!

Id have thought that the hob will limit itself to drawing no more than 2kw when plugged into a 13a supply. So that would be one ring at full.

Even with diversity I can't see how you wouldn't end up with reduced power to each active ring (drastically reducing the more rings you have on) and therefore longer cooking times.

Are they perhaps assumeng you'd use them on dedicated spur and are just using a 3-pin for ease of replacement/storing them out of they way?

If you've got them on the kitchen ring what happens when you have the kettle & tumble dryer on, might as well shine a torch at them as use the hob

Andy L : Yes, thats my point, most manufacturers of electrical equipment tend to limit the draw to 2kw on a 13amp supply as obviously on a ring main there is other devices (kettles, tumble dryers etc) which will add to the load on the circuit and potentially exceed it.

As the hob will often be used for more than 2-3 minutes (as opposed to a kettle which can go to 3kw as that would be acceptable for a short length of time), then you would have to limit it.

Really don't think its a good idea plugging a hob into a 13a supply, it would be far better to have a dedicated circuit, or even break a ring main in the kitchen to create a radial circuit if thats feasible.
