[QUOTE="johnb2713, post: 529057, member: 35153"] Hi, I am a sparkie by trade, now retired but have always done heavy electrical work i.e. rolling mills, arc furnaces etc. I need to run a cable to my garage, it already has one but I'm to install a battery and inverter in their which will need a bit more capacity. I intend to run the cable under my block paved drive and really need to feed it from the Henley blocks / meter tails in the external meter cabinet. The cable run will be around 10 metres end to end and I can squeeze into my meter cab and isolator and mcb to protect the cable. Looking at my incoming 100A supply, it seems way too small, but it's there and has a 100amp fuse in the termination unit. Could I please have your thoughts on cable size, I'm thinking SWA 10mm+ ? 50 amp breaker between this cable and Henleys, or should run a cable duct and meter tails? I have to run conduit / duct anyway for the CT's. Is it OK to use the armour as earth or is that now frowned upong and therefore 3 core cable needed? Yes, i do know the DNO's can frown on equipment added to meter cabinets but I do have room in mine ! Any help / advice gratefully received. [/QUOTE]
