Hi, i am wiring up my kitchen and want to fit a grid for my fridge, washing machine, hood and hob. Now i have wired the grid into the kitchen ring and then have taken 2.5mm from the grid to each of the appliances mentioned. I have brought a 4 gang grid plate for my 4 appliances. My question is, for the washing machine and fridge i will put single sockets and for the hood and hob i will buy 2 fused spurs with flex outlets, is this ok? Also if i do this will i only need to get 4 x 20a dp grid switchs?
