Just picked up a small (10W) LED pir floodlight. The instructions
said that it must not be connected directly to a lighting circuit,
but only via a fused and switched spur. It's designed for external
use; I can see the logic of having an isolator, but is that actually
required by the Wiring Regs?

Since it can switch automatically, you must have a means of isolation
to make it safe to work on. The fusing would depend on what rating
they require. If the requirement is adequately met by the circuits
protection then you could argue there is no need for additional fusing.


Thanks, I wondered if that was the logic. Although since it is almost a
black box and the bulb isn't replaceable you might argue that the only
"work" you can do to it is to replace the whole unit. Many of them come
complete with a wire tail. And you wouldn't normally disconnect it from
its isolator without isolating the isolator, would you.

Still worth having a switch there, especially on stuff outside. Much
easier to check to see if its the thing tripping your RCD or MCB etc,
when you can flip a switch rather than climb a ladder and undo connections.
