I want to use this cooker cable to power 4 induction hobs rated at 3kw each. Is the picture I've attached a safe way to do it or can I even do it at all. Any advice is greatly appreciated!
They need to all be turned on at the same time but will probably never be set higher than 2000w each, although they can go to 3000w. The ideal cooking temp for them is between 1200w and 1500w. They are Buffalo Induction Hob CE208-03.
I think you may need to upgrade the mcb as you’ll be running right on the limit of 2kw each. The size may be limited by the installation method of the 6mm cable. 2.5mm is inadequate between JBs The other way of handling the junction boxes is to use a second consumer unit with 4 16A MCBs
According to the manual, those hobs come with 13A plugs (with a 13A fuse) - why do you want to change to 16A, which is presumably unfused ? http://www.buffalo-appliances.com/media/manuals/user_manual_ce208.pdf
Why? The RCD board will allow 80a, and so far there is only the 32a mcb for the cooker and two 6a mcbs. So that 32a can be upgraded to a 45a. And 6mm t&e is rated for 47a. Why is that dangerous? Please help!
Isn’t the issue overload protection on each “leg”? Those hobs need 13a fuse (apart from anything else)
