Nice one,wish all fault finding was as straight forward as that one

Assuming it's a 5W lamp, 5/240 = 20.8 mA so all that current was going to earth hence why it only tripped on full power. Most RCDs trip in the 20 - 30mA range.

It's so satisfying when you find it

I'm 45 seconds in and I'm guessing crushed line to neutral from improperly terminated downlights! 😂

Was never going to be the dimmer mate

Should have been identified when the inspection and testing was carried out which suggest it wasn’t.

Had a job Extractor fan turns on with lights but can’t be turned off without turning it off at the breaker, no humidistat or timer present, 12v downlights Only thing i think it could be is the transformers but still don’t make sense

Love the videos, but I listen with headphones and the constant sound of chewing gum chomping🤢😬😬 keep up the great videos 🎉

Its not alwsys that easy
