Need to order the consumer unit for my garden shed and thinking about the MCBs to use...
It will be run off the house consumer unit... currently have a 32A MCB spare, in 6mm cable all the way to the exterior SWA terminal - from then on it is buried 4mm SWA (10m length) up to the shed.
For the MCBs in the shed, it looks like I'm limited to 20A (ring), 6A (lighting) and 6A (alarm).
Would this be ideal or is there any way I can push the ring to be higher than 20A? The next MCB up is 32A... which would mean a 40A MCB in the house... then connecting the alarms to the lighting MCB (6A) totalling 38A... applying diversity and all of that this should be OK on 4mm SWA right? Just wanna minimise the chances of music equipment tripping out from overload.
Thanks.
