    Any tips for my am2???

    Use the reading time they give you to read over the task in hand. Don't rush it and try jump into it. Use the time you have, there is plenty of it, and there is no extra prizes for finishing in half the time. Follow the task instructions you get given for inspection and testing as it lists the...

    Advice on additional work

    Look at it from a positive perspective, at least you got paid for a learning experience! Might be £5/10/15 after you pay for everything but you've learned some very valuable lessons from it and I'm sure you won't ever make that same mistake again. Could have been much worse! Best of luck...

    Didn't realise you could PATest a lighting circuit 1.0 min into the vid approx

    I find their videos very informative. They have put out some of the better content on YouTube! However in this case I think he said "perhaps tested" which when said fast and rolled together with the next word did sound like PAT :p

    Possibly just me but i just get really insulted

    I'm not sure why you'd take insult from it. These people are trying to make a career change and are doing it out their own pockets. It might not be the most ideal way of doing it but there is really no other way. The positive from that is at least they are trying to gain practical experience by...

    CSA and resistance of 20 & 25mm Steel Conduit

    I'd imagine that you could use the formula R = ρ*L/A With ρ being the resistivity of the material, L being 1 metre, A being the CSA in m²? I have however found something that may help you, I don't actually know where the information for the table was sourced from, so you'll have to take it...

    CSA and resistance of 20 & 25mm Steel Conduit

    I did have a big table of the figures but I can't seem to find that, however I did find this. IET Forums - CSA tables for steel conduit?? - http://www.------.org/forums/forum/messageview.cfm?catid=205&threadid=24288 GN1 seems to get named dropped a lot and if memory serves me correctly, they...

    Course of action after apprenticeship.

    In my opinion the smart move would be to stick with the company who just paid to train you for at least a year to consolidate all you have learned and continue to build on what you have already experienced. There is a lot more to the job than what you learn in your 4 years.

    Garage Sub Board SWA sizing

    I'd discuss it with the client and explain the differences and what they want to do. As mentioned by others, the cost per meter is minimal at those sizes and it gives piece of mind. If you're really worried about it, why not lay a length of ducting for the cable to be pulled through and then...

    They could have at least used sleeving?

    So many questions. How did they manage this? Why did they do this? Did someone finish that job and think "job well done" before screwing the cover on?

    3 phase motor over current formula

    I'm sure they mean part P. Everyone knows I x V x p.f. = part P

    3 phase motor over current formula

    Never even noticed that haha! Thankfully it wasn't me who typed it up, but I think the theory behind it is sound enough.

    Moving onto nvq 2357 from 2365

    I believe they all transfer over however you have to attend a 1-2 day course and maybe sit an extra exam to sort of "bridge" the gap between the content.

    Can a dimmer switch be used to control drill speed?

    I'm not sure if the mechanism the dimmer switch uses to dim would translate very well for the drill, and I'd be sure to pick a dimmer than could handle the 400V but like @telectrix says, best way to find out is try it out! Be careful and don't get hurt with your experiments!
