[QUOTE="Andy™, post: 520815, member: 2012"] not really. overload and fault protection are 2 different things. if, by nature of the load, if the circuit canot be overloaded then overload protection doesnt need to be by the MCB, you only need to provide fault protection, which in almost all cases, 32a MCB will protect a 2.5mm t&e which is why you can take a 2.5mm spur form a ring / 32a radial to one point, as the max load possible is 13a (yes, i know a double socket could have 2x 13a loads, but regs still consider it one point of 13a...) so how many of you dont agree with a 2.5mm cable from a 32a MCB, but also dont have an issue with a spur from a ring? whats the difference?
