take our house fore example, 22 circuits on a standard domestic 2 bed bungalow, inc pond (4 SOCKETS) and sheds(1 LIGHT 2 SOCKETS) and greenhouse (1 SKT 1 LIGHT)), (pond on seperate supply to shed and greenhouse) garage sockets(6SOCKETS), cctv circuit(4SOCKETS), lights (6) and fan and mirror light in bathroom, lights in kitchen (16) and outhouse (3) /pantry(2), heating in bathroom towel rad spur (1), boiler/heating (1), up sockets (12), study sockets (10), alarm(1) , security light(1), outdoor lighting(12 low energy downlights), downstairs lights (15) inc downlights), up lights (18 iNC LOW ENERGY DOWNLIGHTS),lights in study (10 low energy downlights), sockets kitchen (11), sockets down (15), internet/netork supply (2) , outside sockets (2), shower (1), cooker (1) so you see our house is a standard house setup but has lots of circuits to test due to keeping all circuits on as small amount of power loss as possible. would you say on our per circuit, or would you just see how big the floor plan is,
