[QUOTE="MrBenn, post: 392761, member: 4856"] I understand that you can protect a cable from the field end in the example of: a spur of a ring protected by a single socket 13ax2 plug tops or fcu 13a I wanted to know if theres a written regs or guidance in another book regarding supply of control wiring from larger supplies. I.e. Emergency stop contactor being fused down but supplied by 100a fed to the distribution board. I've explained the theory but my supervisor wanted written guidance which I'm struggling to find maybe Ive missed a keyword? whilst on the subject sizing the cable feeding the fuse carrier/mcb is it a case of working out the max allowed per meter ? Ive noticed a lot of different sizes in panels and control systems. . I hope this makes sense. Cheers in advanced [/QUOTE]
