Thanks also!

Thanks for the reply, whether the downlights are LV is something I will have to check! I only looked at the job for a few minutes and left due to not feeling very well. Sounds very promising though, I will let you know tomorrow! Cheers

Hi, I have a fault on a lighting circuit in a commercial premises. Power is fed to the switch and a single switch wire and neutral goes on to feed five downlight bulbs and then onto 3 LED'S. If I turn on the switch neither the downlights or LED'S come on and the MCB cuts out, although if I turn...

Hi, obviously the longer the circuit the higher the resistance value, providing there is no increase in the csa!

0.05 is just relevant to bonding conductors not cpc's!!

You can check the milli ohms per metre resistance for the relevant cable or individual conductor from the on site guide... times this by the length of the circuit and divide by 1000, your reading should be comparable. I also have no idea where your figure of 0.07 comes from! Otherwise your...
