Fcu

[DuaneMHunt1976]

I did two FCU off a ring in 1.5mm got ask were I got that I dear it was okay to do that, from the wiring regs 2008:2011 at the back a ring circuit, the examiner said it was wrong..

Sorry mate both of your post are really hard to understand, you need to take your time and build your sentences correctly
Duane I could be wrong but looking at your qualifications, it seems that you may be a trainee, not having a dig at you but if you are indeed a trainee, then my advice would be to ask the Mods foe access to the Trainee section, you will find more sympathetic help in that area, if you have a copy of BS 7671 then take a look at Appendix 15

nothing wrong with it in osg (yellow amd3) page 183 (green p175 amd 2011)

because the fcu is a fixed load you are providing overload protection downstream so it cannot overload.


(wire to them in 2.5 next time or better incorporate then into the ring)

If under 3meters. IMO in not really the done thing though.

If you have fitted an FCU into the ring then the cable on the load side of the FCU can be 1.5mm² as the current is limited to 13A and 1.5mm² is the minimum csa for power.

If you take a 1.5mm² cable and join it to the ring and then put an FCU on the end of the then the 1.5mm² cable may be able to take the full 32A current and this would be incorrect.
It is technically permissible as backward fusing but generally would not be correct without care.

Includes other requirements too IIRC...

That's what I did, but was told the regs book was wrong in saying that

Who told you the regs book is 'wrong'? Get them to put it in writing and get them to state why their opinion should take precedence over the regs.

 

[Richard Burns]

Just what I was about to post!

 

[Andy78]

Far too little information.
Who is the person who cribbed your work ? what was the original job ? how exactly was it installed ? which regulations specifically are in question ?

 

[Marvo]

I haven't been this confused about a thread for a while....and what is 'cribbed' just out of interest or did the spellchecker do a number on your post?

 

[uksparks]

If spurring off a ring to a FCU, I always do it with 2.5mm as you never know what some clown is going to do later on like change the FCU for a double plug and disconnect the rest of it maybe.

Cribbed = snagged. To have something pulled up for attention or possible remedial work.

Thanks, I thought it was slang for copying but it made no sense.
