Spur from wall socket to ceiling

[crystal ball]

Apart from the energy saved in a multi projector establishment by switching off, it may prevent a fire by the simple action of switching off. When I was on holiday last month I unplugged all but essential equipment, without using a broom

Although having an accessible switch is clearly highly desirable, I'm not sure that it has to be in an FCU. If all that is at the end of the cable is a single socket (into which a fused plug will be plugged) that downstream fuse will normally be enough to allow one to feed the socket with 'smaller cable' (albeit never <1.5mm²) whether or not there is an FCU).

Kind Regards, John

What if someone plugs a welding set into the socket

Well, there's someone else here you should probably be asking that

However, if the welding set had a 13A fuse in its plug, then 1.5mm² cable would still be fine (and regs-compliant).

It may be but not in my world

I'm not sure that I understand. Are you suggesting that having a second 13A fuse (in addition to the one in plug) in an upstream FCU would make some difference?

Just my way of doing things, I only carry SFCUs or FCUs as stock in the van, I always fit local isolation despite the proximity of a handy broom, always fit clear labels and still the teachers leave them switched on for the summer hols, call it belt and braces if you want

Fair enough. I fully understand the desire for an accessible switch, and would certainly fit one myself in the situation we are discussing. If your only reason for using an SFCU, rather than a switch, is because that's all you have in your van, then fair enough.

However, do I take it that, despite what you appeared to be saying, you agree that the fuse in a FCU is not necessary to permit the use of 'smaller' (I presume you meant 1.5 mm²) cable, if all that's on the end of the cable is a single socket (and even if someone plugs welding kit into it!)?
