Hi all, I've just been talking with a kitchen fitting company as we're currently looking at (surprise surprise) getting a new kitchen. Anyway, we are wanting to add in a dishwasher, and also replacing the existing freestanding fridge/freezer with two separate under counter ones.
I've tried to draw out what is being suggested, given a picture is worth 1000 words and all that. Black is existing, red is what's new. All the wiring is 2.5mm T+E
As I understand what they are proposing, is to replace the existing back box of two of the existing FCU with a dual back box. Take one of the ring wires into one of the FCU, and the other wire into the other FCU, and then connecting the two together. Thereby effectively adding in an extra FCU to the fixed ring. There was talk about using a MK Grid plus with two switches and two fuses so it'd all fit in a standard 2gang back box - but the idea is the same.
I understand the adding of the FCU's to the circuit - the logically and physical actions of connecting it all up all make sense. However my concerns are mostly around the loadings all that could put on the circuit. I know we're mostly likely going to have both washing machine and dishwasher on together overnight (according to their spec's they can both pull in 10A) so that's a possible 20A before anything else. I've been trying to find out this afternoon some info on the others.
I'd rather be able to say now to the kitchen company, nope we have to have an additional circuit, and that all get costing in - than have the kitchen finished and then start having it trip when things are on. And then start having to change circuits etc.
So could I:
a) check that is this an ok modification to the circuit for them to be suggesting?
b) should I be concerned about the loadings of this circuit.
Thanks all.
