Got a nice little challenge.
As crow flies distance CU in house to new Garden Office 17.4m
However route cable needs to take around obstacles etc if stay outside/buried c20-22m. But mean cutting through concrete slab and patio... not welcome.
Got an option to make it much easier for self (and not wreck expensive patio etc). By going via the garage. Distance house CU to garage 5m. Garage to shed 8m. They form a nice 90 with the garage at the apex. Would have to transit inside the garage at ceiling height.
Cannot use the circuits in garage as already in use got it's own connection to the House CU.
House CU will 'probably' use a 40A MCB
SWA is 2.5mm 3 core (I have remains of a 100m reel already)
Garden Office will have a 'garage unit' 3 way 1x10A, 1x16A and 6A. (Spilt A/C, Socket and lighting)
The question is this:
Do I use one continuous run of SWA from House CU to shed irrespective of through garage or not (would fix to wall about 100mm AGL) or do I break it and go house to garage then garage to shed with T&E inside garage between lengths of SWA? SWA cable isn't expensive that said I have some metal enclosure 60A joints as well. Having to redo the patio will be Obviously will have to be aware of the bend radius of the cable.
Sparky will connect it all up and test to be certified but I doing the physical work (trench, holes and cable pull).
Please be gentle
