Furthermore, the circuit supplying socket-outlets in the garage will require additional means of protection from an RCD having the characteristics complying with Regulation 415.1.
What size SWA cable do I need for shed?
Unless using an inverter freezer the volt drop is rather important, so if coming from the consumer unit about 42 meters is the limit with 2.5 mm SWA cable with a 16A supply. With 1.5 mm SWA same current then drops to around 24 meters.
