I think i'll be ok. It seems most people fail on the testing and fault finding, I have no troubles with that, I very often go out alone finding faults and doing perodics for my company. Its one aspect of my job i really enjoy. They give you an diagrame for the heating so no issue there. most things are wired in singles, so no issue there again. Health and saftey no problem. I've never touched data cabling and havent done much SWA work and a few poor terminations of swa cables at my previous company i was never shown how to do that correctly.
I've found an guide with all the details and how to wire everything and which breakers to use ect.. But i was told theres 3 versions of the AM2 and you could get any one of the 3 on the day. Reading through the document i dont think i'll have any real issues. Plenty of time to get practice on SY and data cabling. PLuss im doing an revision day Hopfull ill sale by.
