Hi everyone I have just brought a new oven and hob calculating up to 12kw together. I have spoke to an electrician who gave me a price to connect them. He asked if I have a connection unit, I advised I was not sure. But I have a cooker switch. Basically everything I had was fine, but have now found out that the connections for my old hob and oven have been made directly to the cooker switch as I don't have an outlet plate. The reason I replaced these alliances was because the RCD started tripping out a week ago after over 7 years. I want to know if the way the wiring directly to the cooker switch is correct. 1 cooker switch, no outlet plate and 2 additional wires (Oven and hob) connected directly into this.
Use a 45Amp Easy fit Dual Appliance Outlet Plate, a neater solution. https://www.tlc-direct.co.uk/Products/AA45DCOP.html
Na I wouldn't. I'd use one of these. https://www.screwfix.com/p/mk-45a-cooker-connection-unit-white/16686 By the way what size cable do have to supply the cooker? Do you know what the kw rating of the old cooker setup was?
Hi It’s a 6mm cable, I’ve had an electrician out who said it’s not ideal without the cooker outlet, but that should not cause a trip as it’s in a 45amp switch. He’s now advised a test on cables to ensure no break in there. The to change the switch, if that does not work it’s a faulty appliance. I’ve heard a lot about the dual cooker connection, but would it not do the same as a normal cooker connection The oven is 5.3kw and hob is 6kw
Not sure why you think the single outlet is a better option than the dual outlet, i find the dual a much neater option then cramming 3 cables into a single outlet
might be a single outlet but it has absolutely massive terminals that can easily accommodate 3 lots of 6mm. front facing terminals with a cover plate makes life easy
You are concerned about RCD tripping. Anyway, replacing the appliances should resolve it. It is usually a faulty appliance when this happens as there is little to affect the wiring unless it has been damaged by external factors. Connecting two appliances on one circuit is allowed. The fact its been connected directly to the 45A cooker switch is not an issue, it can be done that way. The alternative is to use a dual outlet plate but all that does is make life easier it doesn't add or detract anything to the circuit in terms of safety. Standard circuits for cookers, wired in 6mm32 T&E are normally good for total loads up to 50kW. As other posts have mentioned, the diversity of loading on the circuit means it will never be overloaded and even it it was it would simply trip before any damage was sustained to wiring.
Thank you everyone, as I'll be changing them both, the electrician has advised he will check to see if there are any breaks, if not once I brought the new appliances he will fit them in as he too thinks it's either the socket itself or the appliance
