[QUOTE="lavenderminx, post: 344656, member: 23672"] Be gentle, this is my first time on a forum. Anyway, having new kitchen fitted and wanted to update the wiring (Scots regs))......... was going to run 4mm radial (32MCB) t&e cable to a 4 gang grid for(fridge/freezer/dish washer/washing machine) then from the 20 amp DP grid switch run to each appliance a single cable (no more than 2meters in length each) ending in a non switched single gang socket (all aplliances have fused plugs) Can I drop from 4mm to 2.5 from 20amp DP switch to socket?or does it have to stay 4mm? The rest of the kitchen is on a 2.5 mm (32MCB) t&e ring with a number of double gang sockets (5 in total). On this ring I have a second grid (3gang) Microwave, extractor, undercounter lights) all 2.5mm cables as this size cable is easier to wire. Again all fused plugs so due to the 20amp DP switch am I right in thinking i don't need a FCU, just a single gang non switched socket? Large double oven/hob is on 10mm dedicated radial. How does that sound? Will have it all PIR tested, but wanted to check before I go ahead. Any suggestions greatly appreciated. [/QUOTE]
