[QUOTE="m4tty, post: 176066, member: 2412"] Hi, Whilst working the other day I saw a submain fed from a switchfuse. The cable used was 16mm 3 core armoured and the switch fuse protecting it was 100a. Length of run to submain was roughly 15m run above suspended ceiling. Is this ok or should 25mm cable be used. I've looked up ccc for 16mm in osg and it's 87a I think off top of head. But think the swa can handle bit more than this but can't find it in brb. Can someone point me to correct page? I've only done domesic and not alot of that so am looking to learn as much as possible. Thanks for any replies. Cheers [/QUOTE]
