Scrap the Ring final circuit

Discuss Scrap the Ring final circuit in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

Not a fan of RFC's, the only advantage I see is saving space in the CU; disadvantages include the obvious dangerous one where a broken leg creates two 2.5mm2 radials on a 32a MCB that is undetectable until something serious happens , more awkward to test, more awkward to create alterations, more awkward to fault find. Two 20a 2.5mm radials use less cable than a RFC and are much more versatile IMO
 
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
 
Found this on Friday:

[ElectriciansForums.net] Scrap the Ring final circuit

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.
 
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.
