I recently ran a post on shed electrics which mainly was due to running a submain off the original consumer unit. Having had a look at the unit i only have 3 spaces in my unit - 1) lights 2) sockets 3) cooker. I have a separate electrical supply just above the cooker, which at the moment only serves the boiler, washing machine and kettle.
As there is no spare slot in the consumer unit, could i wire up a feed from the "cooker" slot to a garage unit in the shed? or is there some other way of doing it?
