Hi all,
As title, I have two 15W LED PIR security lights running through a switched FCU and they are blowing the 3A fuse within in. I would have thought 3A was way more than capable of handling that load, is there something I'm missing?
A bit more detail if you've got this far:
We've recently had the house extended and the lighting circuit was added on to a spare way in the CU on a B6 RCBO. The builders also ran some cables through the roof void for me to add some security lights at a later stage, leaving them unconnected either end.
Fast forward a few weeks and I fitted a pair of 15W LED PIR lights, wiring them through an exterior rated junction box since the lamps have a fixed flying lead. A colleague/friend/qualified electrician then came and connected these up to the CU for me, to the new B6 RCBO, and through a 3A switched FCU so that I could override the PIR and have them on permanently if I wanted. Tested briefly and they were working fine.
I never thought any more of it, but having gone out in the dark for the first time the other night the lights weren't working, and it seems the 3A fuse had blown. I swapped it out and they came on but went out within a second and won't come back on. The RCBO has never tripped though which seems strange.
Unfortunately said electrician is abroad on his jollies so don't want to disturb him, so wondered if anyone has any advice in the meantime please.
Thanks in advance,
Andy.
