Hello, I am looking to work as an electrician's mate. Within 2 weeks I will finish C&G 2365 Level 3 (started September 2015). I have been studying a lot and have good knowledge of science, design and inspection and testing. My next objectives are: NVQ, AM2, JIB Gold card. I have 17th...

Aha that's right, sorry. :D Thanks Dave, very interesting. It does sound very complicated. I should ask him again and quote your posts (Andy and Dave).

So I could measure current and apply Ohm's law. To get significant values in megohms at, for instance, 400 V I would need an instrument that can measure extremely low values of current. 400 V / 0.0004 A = 1 megohm.

Obviously the circuit/installation tested should be safely isolated, but... This is the story: our tutor asked us to find out how insulation resistance can be done on a live circuit. He had to do it once to test several circuits at a military base, and the "client" specifically requested that...

Ok now I'm confused... I thought it was a decent place but you are telling me it's a ****hole. How did you form this opinion? If it wasn't for the ridiculous traffic congestion and the larcenous cost of putting a roof over my head, I wouldn't mind living in London. Manchester is cheaper and...

Thank you Evans and ProDave, you convinced me. :) Sure I could avoid big cities, but I can't live in a place that is too ethnically homogeneous and/or monocultural. My spirit would suffocate. Have a look at this page...

Hello, I moved from Italy to London 4 years ago. I am about to complete level 3 and will complete NVQ within the year. Since I moved here I've only visited Edinburgh, Bath and Brighton, so I have no idea what the North West looks like. I was reading about Manchester and my impression is that it...

Thank you Sharpend and apprentice87! Yes I'm still a student, hated by my teacher because I ask too many questions. That's why sometimes I have to come here and ask questions (and I always try to find the answers first, books + Internet usually does the trick). I totally agree about your...

I wouldn't worry too much about people like me who study and ask questions when they don't know, and keep reading and studying to learn as much as possible. I would worry about all these electricians who know, but are not bothered to work properly, or who don't know and don't care. I had this...

Thank you guys, clear and concise as always, and a nice picture. :)

Hello, I looked everywhere but I'm still not 100% sure about the difference between: service cable, service head, meter tails. I thought the service head was the bit of cable between the meter and the main CCU, but then what are the meter tails? I've got 17th Edition tomorrow, good...

I think Amendment 3 introduced a regulation that prohibits that, I would be careful. :D

Ahah, I only had to divide by the factor in the table then. I was reading 5.5.2. Thank you for your help roys. :) For your information, Appendix 11 was deleted by Amendment 1 and moved to Appendix 4, secs 5.5 and 5.6.

Hello, I will take 17th Edition soon and I was doing practice questions with a simulator. The only answer I got wrong was the third harmonics one, I read it on the Regs but I don't get it. Would you be able to help me with a demonstration of the calculatioins needed to find the answer? Where a...

This is from a thompson training, they offer the normal course (£400) and distance learning (£200). Their website looks very legitimate, they also have the normal courses. Looks like I'll have to phone City & Guilds to find out, I'm really confused. :D
