Morning all, I'm new to my company and one of the tasks they carry out is installing a kettle lead into a fused spur. Now I think they should have suitable and sufficient training anyway to carry this out but as the purse strings are tight "best practice" is not at the forefront of the bosses minds. This is where I need your help, does anyone know what training is required to work from a fused spur if any. I've searched online a couple of times which brings up the 17th edition BS7672 but we don't have a copy of these at work for me to read. Before anyone says it I know to prove competence they should have official training but I need something with a bit more meat on it to take to the directors as this affects nearly 80 of our staff only 2 of which are training electricians. Any help is greatly appreciated

Is there a reason why you think it hasn't been installed correctly just because money is tight doesn't mean the work hasn't been completed correctly. Are you saying one of the trainee electricians carried out the work then surely ask them to show how it complies to 17th edition. Also a bit lost hoe you can have trainee electricians working for the company without any qualified electrician as they would need to be supervised at all times and all work they carry out, i would be more worried about that. I think the issue needs resolving with who ever is responsible for maintenance work and at this point you don't need to involve the board of directors can't help help but feel they won't thank you especially as you seems unclear if there is or isn't an issue. best of luck Phil

Ill try and explain the problem a bit better. We current install and service electrically operated doors (think entrances to Tesco etc). We don't install the mains power from the fuse board we have a fuse spur left for us to connect into. Before me they were removing the fuse and wiring the kettle lead into the spur which runs approx 1m to the door and then replace the fuse to power he door up. I have stopped this process and operate a LOTO system from the mains before any electrical work is carried out The problem I have is of the 8o ish engineers we have only 2 have any electrical qualifications which would allow them to install the cable but none of the other engineers would but I'm not sure if they have to have any formal training to complete this last section of wiring s I'm sure our competitors don't do the same I know best practice would have all the engineers trained but I'm not sure exactly what training they need and what the legal requirements are. Which is why I need the help of the forum Hope this clears any confusion up I come from a heavy mechanical background so electrical installations even this small are a little lost on me.

Hopefully a qualified electrician will come along to answer your question. But if i where you i would talk to your qualified electrician and ask their qualified opinion on what work they should be doing. i completed a mechanical to electrical course with city and guilds which was a three week course which allowed me to re-set trips and install 3 phase motors as well as carrying out live diagnostic checks so very comprehensive for a 3 week course. may be you need to look along these lines long term , but i would talk to your own electricians first if you think they aren't telling the truth then get advise from a college that run courses or the governing body for electricians to clarify. I'm a bit lost with what you say about wiring a kettle into the fuse to operate the door then changing it back to the door surely there must be other pluga around if they just need to power a kettle. i would have also thought your company procedures make it clear who is authorised to carry out what level of electrical work even it is just wiring into the spur already provided by another company some level of training would be required no matter how simple it may appear as you would need to check if the supply is isolated or live.

If you LOTO at the board, aren't you disabling an entire circuit (yours being a fused spur)? Such a process might be OK for new builds of course. From a Regulatory p.o.v. of course the electrical "system" comprises the fixed wiring and all things connected to it. This suggests that there should be (at least) an installation test by a qualified electrician to confirm earth continuity etc.?

Hall, There is another way around this problem, why not request that whoever installs the supply connects to a suitable 240v IP rated switched socket instead of the fused spur, you could then supply your door with the correct plug and a cable already installed, you would just then be able to roll up (pardon the pun) and plug them in.

The Kettle lead is plenty apparently to power the unit (low voltage after then transformer. Ron, Yes in essence I prefer them to isolate the hole circuit before they remove the fuse mainly because I wouldn't trust the spur (too many variables) I see what you mean though because it would be classed as fixed wiring (into the spur itself) then this would require a form of qualification but our guys don't need to be electricians just to install from a spur I wonder if there is a course for this?

That might be something I can work with cheers

That solution may well end up as an argument about PAT!

A kettle *lead*, not a kettle! AKA a length of flex with an IEC C13 connector fitted, to provide power from the fused connection unit to the door installation. I would have thought the easiest solution would be to request that the FCU (or spur, as you put it) is supplied with the C13 cable, length specified by you, already wired in. Then your fitters wouldn't have to mess around with the wiring, and could just plug in when they are ready. P.S. the 17th Edition Wiring Regs are BS 7671, not BS 7672 (Specification for compression, stiffness and labelling of anti-embolism hosiery, no less!).

Hi Grizzly Thanks for the respons I am looking into that currently as it would reduce alot of the headache but at the same time this would be possible on all occasions (replacing old kit etc) so i would still need to know what kind of training is required to work from the FCU

I think the problem you have is someone carrying out an illegal and dangerous connection here my friend. The fused spur is most likely part of a ring main, fused at 13amp at the spur and connected to a 30amp MCCB at the main Distribution Board. I would assume that the kettle is connected to the live side of the spur (for convenience in making a cup of tea while working at the door area) and not the fused side (which would probably overload the fuse if anything else is connected ie: the door) If this is actually during the door manufacture in your workshop, nothing else is connected to the spur and the kettle is connected to the fused siade of the spur, then I see no problem From an old (very) time served electrician

Hi Lamond, Its not a kettle wired into the ring main its just the term we use for the lead which his pluged into the door headers transformer which powers the door (it looks like the old fashioned kettle leads).

Hi Hall40714, I think you will need to employ some qualified electricians. How do your door installers wire up the controls for the door?. All the wiring must be tested and inspected with a test certificate produced. I am surprised clients don't ask for a minor works certificate. For training try the NICEIC web site and contact them for competent advice. from a qualified spark

hall, most of the other posts above seem relevant. Firstly the "operatives" must be competent. This means knowing and understanding safe isolation according to industry standards and being willing, able and actually undertaking this before working. This could be no mean feat on a "spur" connected in some premises as it could mean isolation of a large circuit. Which, first of all they would have to positively identify and confirm before isolation, then liaise with the customer to perform isolation then undertake the safe isolation procedure and secure the circuit. This could not be a 2 minute job. However, IMHO working within an "FCU" would necessitate full isolation of said device according to EAWR as even if switched off with the fuse out there are still live conductors within the enclosure. Does this help, or do you need more? Paul
