Is it allowable to switch multiple circuits in a grid switch? Let me explain my intentions:
I am designing my new kitchen, and am currently doing the best bit: designing the wiring. Oh yeh! Stick with me for this one, it takes some explaining.
Currently my kitchen is supplied by a 30A radial to the oven and hob (via cooker switch then FCU), with the plug sockets on the 30A ring for the whole flat. I am planning to have a fridge/freezer, oven, gas hob, cooker-hood, washing machine, dishwasher, kettle, and microwave in the kitchen. So, in terms of current draw, that's a fair old whack if you decide to roast some beef whilst washing dishes and boil-washing socks at the same time, and making a cup of tea.
So, what I am hoping to do is to use the existing 30A radial to supply the oven, hob ignition and washing machine (via separate FCUs)... Even on maximum draw they won't be pulling the full 30A between them, and the oven and washing m/c are the most likely to be drawing full power at the same time. I plan to install an additional radial for the fridge/freezer, and a new ring to supply the rest of the kitchen.
Here is where my question starts:
Is it acceptable to switch separate circuits inside a grid switch? I am hoping to use an MK grid switch (8-way) with printed switches for each appliance. But I will be switching from 3 separate circuits if I do this.
Also, is each module totally separate? i.e. you wire from one to the next, or are there rails? I am thinking the latter is unlikely, but thought I would ask.
