Question for the experienced

[Burnt Fingers]

Been PT testing last week (yawn) and have a odd one:

13A Double Socket with a 2.5mm running 10" toa 16A Comando Socket, which feeds a circuar saw. It needs to on a 16A socket or in winter, the inrush pops a 13A cartridge use. Its a ring main to the socket, protected by 20A Type B Mcb.

16A Socket is cracked so I want to replace it

I cannot find anythng in the regs but it feels wrong. Anyone wlling to give a helpful answer?

32a RFCs are designed for 13 socket aren' t they why are you putting a 16 amp socket on a RFC?

 

[Burnt Fingers]

The RFC is 20A

 

[Pete999]

The RFC is 20A

Put the 16amp on it's own radial

 

[Burnt Fingers]

I wish - CU is a long way and thats beyond my remit. Appendix H3 OG states radial circuit but a radial from a 20A ring is, in effect a 20A radial so i think by my interpretation its within regs, but the regs dont say much and it just looks odd to me.. sat there next to a double 13A socket

 

[telectrix]

it's not a radial then, is it. it's a RFC with a spur.

 

[shanky887614]

extend on leg of the ring fron socket and add the commando to the ring. sockets are rated at 20amps anyway so its fine

 

[Pete999]

If you are PATesting, test the machine job done, "not my remit to install new circuit" anyway should be on it's own radial.

current rating of saw is -----------

 

[Burnt Fingers]

As usual sorry I asked.

 

[VoltzElectrical]

I understood it (PT) to mean Periodic Testing.

Just re-read the thread, as has been suggested, add the commando socket to the ring. Any reason it's on a 20 amp breaker?

 

[Burnt Fingers]

As usual sorry I asked - however my keyoard is off sick.

As far as I know always been on 20A, other RFC is 32 same building. Unless it was put down to 20 when socket added - its been there a while

 

[VoltzElectrical]

But the only problem is the saw blowing a 13amp fuse, yes? Is the saw suitable to be fused up to 20 amps, as if you add the 16amp commando socket to the ring, it will then only be protected by the OPCD.

In fact, in light of this, I retract my earlier advice to add the commando to the ring. If the appliance is supplied with a 13amp plug top, then that surely is there for a reason.
