hi people a few of you may remember my thread a few months ago about giving up my apprentiship and finding another way of qualifying as the training company that is doing my appprentiship are to be honest quite shocking! (JTL)

anyway long story short, im back on speaking terms with JTL haha got a new training officer that i have seen more in the last two months than the one before in 2 years! i only have my log book to do and this in all complete barring one question that he hit me with the other day, its got to be back with him by the 15th but im away on monday so need to post it this weekend and i have left my Reg book and on site guide in the site box a work.

my question is as follows and any answers would be greatfuly recieved as this is gonna get me my gold card finally after 5 years of messing about haha ;-)



basicly i wired a fire alarm conventional system so one leg out the panel to an end of line, ie radial. This was wired in 2 core+ cpc 1.5 fp 200 gold. im guessing the length of the circuit was about 20 meters maximum as it was only a little gas extinguisant system (small comm's room) i took a reading of 1.9 ohms for the CPC continuity this was obtained by shorting out the cpc and live at the other end then taking a reading on a low ohm meter.

the question i have been asked is

What table did i use and what calculation did i use to make sure it was acceptable.

now if im being honest we dont normally check the regs, its only 24V running at a few mili amps, we only dig out the regs when testing our motor circuits and supplies for the panels and so forth, but if anyone could take the time and dig out a table number for me id be greatfull.


Many thanks

Luke


oh pref 16th edition as that is what was in force when the circuit was tested.




Thanks
