Installing two new appliances
- Microwave Combination Oven 3350W (say 15A)
- Oven 2990 W (say 13A)
The kitchen already has two radials from the consumer unit to which these will connect, with 20A RCBOs installed.
The radial circuits are in 2.5mm.sq cable and the length is okay for voltage drop.
The appliances don't have plug tops so need to be hard-wired each into a separate connection plate, so there are no fuses in place.
Would prefer to avoid replacing the 20A RCBOs with 16A ones if possible. Instruction manuals don't provide any useful information re supply ratings and I can't find anything much to help inform the decision.
16A RCBOs would provide closer protection, but is this really necessary?
