Scrap the Ring final circuit

[sparkdog]

I prefer to do a 4mm radial if its a kitchen.

Have never considered a point from the link that JK posted; voltage drop when covering a large distance from DB.....this argument is not going to go away is it?

 

[davesparks]

Most common thing a DIYer will do is spur off of something, less of a risk on a radial in my opinion. True, we are not required by BS7671 to cater for future incompetence and cowboy interference, but it's another (albeit) small victory for radials

My experience when I was doing domestic work is that the biggest issue with diyers is that they use the incorrect size cable and don't make terminations securely.
This affects any type if circuit

Totally agree Dave, was trying to point out specific issues regarding RFC vs radial

Found this on Friday:



This was revealed when a fireplace surround was removed ... all cables terminated nicely into separate terminals - and on a 32A MCB

Ignorance by the DIYer or builder that did this.

The installer will still be trying to find continuity 50 years on haha......

It's quite simple really. If you feel that a RFC is not appropriate to your install for whatever reason, then don't use one. If you find them awkward or confusing to install and test, don't use them.
But to call for the banning of them because they are dangerous when altered or misused by incompetent people is sheer nonsense. Should we ban cars ? They probably kill a lot more people than RFCs when altered and misused by incompetent people.

Surely the ring final circuit is just a tool in the box of the circuit designer? Use it where it's advantageous, don't use it, it's just an option. If we stop using circuit layouts just because cowboys screw them up then there's going to be no electrical installation whatsoever.

 

[Ian1981]

If bs7671 is followed as close as reasonably practical then there is no issue with any type of circuits installed past,future and present

This socket had been plastered over, presumably when the hose was built, behind a kitchen floor unit. The property had a CU replacement a couple years prior to my work. The 'RFC' had been converted into 2 x radials, as (I expect) the electrician (CU one or original) couldn't obtain continuity, but did not disconnect these legs. I only discovered it, when re-locating the kitchen sockets, and noticed the cable drop in the ceiling void.

Thee are very few specific issues with RFCs which don't affect radials. Poor quality work affects everything.

 

[KennyKen]

Is OP an Aussie? Sure sounds like one.

 

[Pete999]

Radials 1 RFC 0

You realise if RFCs are done away with that means a new set of Regs, new qualifications to pay for, because believe me if it happens, the IET will br rubbing their hand together thinking of the influx of cash, as will the training companies, you can just imagine it.

Can't see why. Remember watching some training video - was a couple of years ago now - Dave Austin demonstrating RFC testing. In his preamble, he said that the EU were going to ban RFC's, not that's going to happen now

If the IET can make money out of any changes, believe me they will, the NICEIC and all the others will go into overdrive with courses, exams ror new qualifications eg I'm Radial trained now.

could then incorporate it into the building regs....... part R.
