So I was doing my usual morning browse this morning, and I have no idea how but I ended up reading a load of threads from years ago about the Dual Appliance Connection Units - it left me with a question that I couldn't find an answer to within those threads, and not wanting to reopen a 3 year old thread, here we are.
So, these:
It looks to me that the supply is thicker than the two loads. Let's say the supply is 6mm on a 32A MCB, and the load is two 4mm cables. If the 4mm goes directly to the appliance (for arguments sake it doesn't have a plug end) how do they get away with using a smaller cable size without fusing it down.
Is it because:
a) There is little chance of overload on these appliances
or
b) A 4mm cable clipped direct will still carry 37A (sorry if slightly incorrect, using older regs) and therefore doesn't need fusing down
or
c) Something else altogether
