The room was empty - No access from above required. Holes made in ceiling to thread through cable
All access was done from below? So you 'stitched' under joists where required? Another non compliance then.
what testing exactly? The lights work or they do not
Quite simple really.
You are so ignorant to believe that just because a circuit is 'working' it is safe and installed correctly.
well I trippped the mcb a few times during installation so yes I know the mcb works. The breaker is 6Amps and works fine.
That says it all doesn't it. Are you aware that if an MCB trips several times on circuit with a high fault current there is a good chance it will eventually fail?
Dont tell me that when you come to fit my downlights you will also be checking for the integrity of all my electrics? Just in case like?
Anything upto the point where the addition is made, yes, of course you would. How about RCD protection to the circuit? This would be factored into any quote, as is more than likely required. Is your main protective bonding upto the current requirements? This would more than likely be factored into the quote too. both items would need to be carried out before additions like this.
The main thing the sparkies who have quoted have factored in is the 'w*nker factor'. Quite often added to quotes after a first meet.
Lets have some photos of your install and your connections.
How many other lights and what type are on the same circuit?
Do you have RCD protection to this circuit? Is the switch drop buried in a wall?
How did you terminate two sets of cables into these fittings?
Are your terminations enclosed?
Have you ensured (and tested) you have earth continuity to the final fitting?
