Wiring for New Electric Hob - 4 wires

[John White]

Brought a new hob Russell Hobbs (RH60EH402B) because the old one was cracked. New one seems to have four wires, but the old one only had 3. I think I need to pull out the oven to get access to the box that the wires feed into. Do you think I will I be able to connect the new hobs wires easily into this box?

No it’s not damaged there’s no live feed to the rest of the hob it depends on cable size into the box and total power rating of the hob

I'm sure it's sorted by now, 2 years on!!?

The wiring diagram with a new Belling Ceramic hob could be better -a lot better. The wires that would have been connected to three phase are brown and black connected to 240 v AC they are connected to the live terminal = out load on the double pole isolator switch. The blue N wire connect as usual to Neutral out Load. The earth wire connects to earth as usual. A good earthing is required due to a fair load = approx 6 Kw.
I don't think I need to check with my lad =he's a sub station electrical engineer = heavy duty at 130 k..
How many commercial kitchens these ceramic hob producers hope to sell to god knows. Usually their hobs are gas fired with six rings or so! The mind boggles.
