I would like to run power to my childrens shed for a light and a socket for a heater.At present I have power in the garage coming from 2.5mm cable which appears to come from the downstairs sockets.This runs into a consumer unit with an RCD and two MCB's .
Can I run another cable from the consumer unit in the garage to the shed into a box with two MCB's using 2.5mm cable or do I need to run a totally separate power supply from the main consumer unit in the house with armoured cable..Please help.
