FCU Spured to outside Lighting

Backtoschoolelec · May 4, 2023

Can I ask a question and make sure I’m not missing something….

Have had outside decking lights in my garden put in by an electrician, using a FCU as the switch for them spured off an existing single gang socket.
Fused a few times over winter, Likley due to water or moisture in the lights or the junction box’s…

Revisited them as the weathers warmed up and now switch does nothing…LED on indicator doesn’t work… I tested it and was showing a reading on natural and earth….
Switched the switch out for a new one and now the light comes on but nothing to the lights.

Pic attached of wiring of socket and have been all over the lights but it’s NO longer tripping the RCD board and just acting like it’s on but no lights…..

Thoughts please and check my wiring diagram please

Can you clarify whether your pictures show the old FCU or the new one.
If the new one then it's damaged and should be replaced.
Also be aware that some FCU's differ in where the supply and load terminals are - they aren't all like the one pictured.
Where is the LED indicator that you speak of?

.........Blown bulbs, perhaps
