I'm in maintenance for a large international company.
I get paid a massive £50 a week, and £25 for 1-3 hours if called out 😂 The only benefit, is if I go home and get called out again, its another £25.
Luckily for me, I live just across the road, so don't have to drive to get there. Having...
If you are aware of the potential dangers, after additional training if necessary, then thats fine to go ahead and install it for people. Some people just seem to plough ahead regardless.
It might be just rare and dangerous, but it will only take just one instance, which might prove fatal...
Your probably right, bit like the RCBO for our main kitchen's commercial mixer, which has tripped more times than the kitchen's given me hot dinners.
Actually, thats not a very good analogy, but you get the idea.
I fitted a couple of those 'Eaton Field Kits'. They are expensive, but what price safety? Bear in mind they are quite tall, and a bit of a squeeze inside a Mem CU, especially if the installer has not been tidy with their cables.
I’ll try to be more succinct. The 1362 fuse can be changed easily. If a lower fuse is used to achieve disconnection times, and is subsequently changed to a higher fuse, then its a poor design.
As said, I think we should agree to disagree.
The addition should be designed around the ocpd at the origin. Take your point about overload, but isn’t disconnection about in part safety to individuals?
Of course they have a table, but are they manufactured anymore? Only because Appendix 15 uses them as such.
My point is, it’s a poor design, to use to achieve disconnection times.
We can go on arguing the point, but guess we should agree to disagree.
You correct to draw an analogy with rewireable fuses and such like. That’s perhaps why they have been made obsolete.
When designing an installation, you have a duty of care to the user. Historically the were just two BS1362 fuse ratings, 3A & 13A, designed to protect the supply leads in plug...
Downlights are all reasonably priced these days, compliant to Parts B & E Building regs. You just need to measure your existing hole in your ceiling to find something compatible.
You have your view which I respect, but however I still think it’s a poor deign and practice, to achieve disconnection time using an FCU etc, because the additional cable is too long or too small, when other installation methods can be used.
I think the concept of a FCU is for the connection of...
Still think its bad design, using 1362's to beat disconnection times, and we can't stop people meddling inside a CU, but swopping fuses inside a FCU is pretty simple mistake to make.
BS7671 supplies notes on uses of an EIC & MEIW, the former typically for new circuits the latter for additions/alteration. A MEIW has provisions for test results for circuit.
As far as I'm aware, a FCU is used to limit current to the extended circuit (same as fuse in plug top to flexible cord)...
