does this comply?

I am afraid threads like this boare me to death. The way I see it a cable that is rated at 28 amps in perfect conditions should not be used on a 32 amp circuit simple if you do its poor design of circuit and why would you want to do it anyway when you could use a 20 amp circuit breaker or two.

so you have never added a spur to a ring using 2.5?

That is not the question the question was would two 2.5 mm radials on a 32 amp circuit comply as said it may comply but is poor design and probably would not be done for many reasons mainly anybody testing board will think its a ring main and too me they could be extended and then probably will certainly not comply.

like ive said before, if you were to move these 2 radials to a ring main MCB, so it shares the MCB with the ring, it would be fully compliant (as spurs from the ring), yet nothing else has changed.

I haven't read all the pages to this thread, and neither am I going to.Going on what you state above; Ian, The fuse in the plug will protect the appliance and cable that it is attached to, Yes. Has this thread turned into a wind up?

I do not think there is any argument whit that but an accessory fuse can not protect the permanent cable installed before the socket.

This isn't a 'special' allowance

How would you explain 422.1.5 then? Looks like an allowance for that scenario to me.

 

[Andy™]

Not. One spur per point on the ring.

what reg?

 

[Lee321]

sorry there are 5 points on the ring.

regardless in the ring example how does the spur get its overload protection?

I wouldn't do that, Even though, it may or may not be in the regs. :|

One Point, per spur on the ring or radial, UNLESS you have added a 13A FCU after the Point at which, you have spurred off, Then there is no limit as to how many points you add to that spur.

 

[Andy™]

WRONG.

then you spur has no overload protection.

now im guessing you have added a spur to a ring main on a few occasions.

you should go back to them all, and remove it since you have omitted overload protection, and it does not comply with the regs.

 

[ianmacd]

I complied with the regs by omitting it for that scenario. The same can not be said for the radial example.

 

[Andy™]

I complied with the regs by omitting it for that scenario. The same can not be said for the radial example.

electrically, its has no difference. its still a 2.5 feeding a socket and protected by a 32A RCBO
