Hi all, I have a question for any qualified electricians out there as its somewhat a grey area from what i can see,its this....
I have steel armoured cable 2.5mm going from my main unit inside my house to the garage in a ring main,
the run from house board to garage is roughly 10 meters to the junction box where the ring main starts.
There are a lot of double sockets in there but the main pull will be 2 electric heaters/radiators, hoping to put two 2killowatt ones in there plus the usual cinema equipment you would have and a projector and electric screen that it houses...
Now the mcb i am using is an rcbo one so it has its own breaker,but do i put the 20amp 1 or can I put the 32amp 1...
Naturally i would much rather put the 32 and i would have ample wattage then but is it safe...
As I understand its roughly 4.5amps per killowatt used so 20amps would leave me bugger all...Naturally if i can only put the 20amp then smaller rated heaters it would have to be but i aint convinced they are good enough.
I am being told different stories from many people,regulation i believe would be around 25amp but i cant find necessary mcb 4 my board...
help please,i really would like to see some consistent info on this
