  • At a guess for the garage you will want to power a couple of KW safely so probably adding a new separate breaker...then running an armoured cable out to the garage.

    Well...

    Need to know the loading for the garage for size cable and voltage drop, need to know the main earthing arrangements from the supplier, need to figure if to use a catenary cable suspension / Hi-Tuff wall mount / armoured in a trench, need to fit a sub-main consumer unit with RCD protection on all circuits in garage, need to retest whole system as it's not classed as minor works...
