This is more evidence of an alarming issue. I often work in the AV industry (broadcasting) and when new equipment arrives, it all looks right, moulded three pin 1363, fuse etc. But look a bit closer, why is there sheathing on the earth pin when it's all stamped with CE and BS1363 etc? And the...
Three of each? Hmmmm..... Is one of those a spur going somewhere? In theory, if you're creating a junction like that, the socket becomes a spur and you'd need to limit the current supplied to that socket with a fuse.
If they've got interactive whiteboards, you can do some drawings on that for them. But, I think you've been given a great opportunity to show kids why what we do is all about saving lives and preventing fires, tell then the dangers of electricity and if you can, show them the basics of what a...
Like the other chaps just said, what is the relevance of the PFC an PSC, when would you get those currents? What would currents of that magnitude do? Would a low or high result be desirable? Answer those questions and you'll understand why you're doing it.
Sometimes when those old lights come out it makes a right mess of the ceiling, especially if there's been a lot of vapour dragged up by convection. I am always heavy on the caveats with this work, but there are plenty of creative ways out of a mess. Most wholesalers will have adapters, but they...
Yep, kitchen is a Part P Special Location so a new lighting circuit is notifiable. If you aren't on a scheme, you need to notify your Building Control before you get started. As for your lighting circuit, you need to start from the beginning. What's the load? What correction factors for...
Not just shower switches, I had to go back and replace a ceiling mounted pump switch the other day. Obviously not a current issue so I took the thing apart. Mechanism was full of stuff from the loft, not suitcases and old 45's, dust and woodlice etc. Think I'll be putting a gob of firecryl in...
You're correct that you would have to notify building control before you did the work. As for the service fuse, you would need to speak to your DNO. Removing seals and fuses is an absolute no-no and needs to be done by the DNO. That's the official line. SSE have an arrangement for scheme...
Like the other guys said, but things as you need them and remember that if you buy cheap, you tend to buy twice. See what your mentor/s use, ask to try them, ask them why they chose them and learn from others experience. I use a FatMax rucksack style tool bag which always keeps my hands free and...
I think this debate will rage forever. My two pennies are a personal anecdote. I had a simple little job to do at an old property, replace a cracked socket front. Being OCD, I did a few tests like Ze, PFC etc and some continuity tests as I could see some interesting work had been done. One of...
That does seen pretty young. Regardless of that, as others have pointed out, you may be called upon to prove your competency. Passing 2382, 2391, Part P and BS7671 17th would be evidence. You may also be called upon to prove how you have kept yourself up to date, joining a P scheme and The IET...
The simple answer is no. The switches are not rated for the current before the transformer. In addition, do you really want to run 230V at 2.5A through each of the cupboards?
You're welcome mate. There are plenty of Electrical Trainee out there who have actually been doing it for years and have decided to be legit and do it properly. I know of some kitchen and bathroom people who quote this Reg and that Reg at me when they haven't got a clue about Ze or U or I or W. Good for you...
Pain, pain & more pain. I had one of these the other day. Eventually traced it to a borrowed neutral AND a pinched cable. The frustrating thing about these faults is they can be so time consuming to find but the only way is to start from the beginning and test from point to point in my...
If you think he should know better, which is true enough, and you don't want to help him, don't help him. I think it's more likely that the old CU has been installed in such a way that pulling the SWA, or whatever the submain is, out and doing a Henley block etc, is going to make a whole mess of...
