Hi all, been a while since been on here.
i have just completed all my 2365 level 2 exams and am completing my practical tomorow..... I have cable tray supporting an swa cable and obviously the tray needs bonding..... I was told by one electrician that this can be in 2.5mm however i have always been told it is a minimum of 4mm when bonding?? What is the correct answer here?? Does there need to be a bonding tag on this?? I also have trunking would this require the same?
Also in my practical exam i have a ring final, radial and a lighting circuit.... There is a 6,16,20 and 32 amp breaker in the consumer unit.... I will be using the 6,16 and 32... I believe they have put the extra breaker in as the radial could go on either depending on how its run.... Can i leave the 20 amp in unconnected? And would i put spare, unused or something else for that slot on my test certificate??
Thanks all
