[QUOTE="androiduk2002, post: 130515, member: 6631"] Hey L plate, A 20A breaker with 2.5mm T&E as per your drawing is an A3 radial which means a maximum floor area of 50 mtrs squared maybe served. You can have a 32A breaker as an A2 radial but this has to be wired in 4mm T&E but this covers a maximum floor area of 75 mtrs . For over 75 squared mtrs there is the ring main: maximum floor area of 100 square mtrs wired in 2.5mm T&E and rated at 32A breaker. Hope this makes it a bit clearer for you buddy. [/QUOTE]
