isolating switches for new kitchen sockets

[EFLImpudence]

Thankyou once again! Yes each appliance will have a single socket, and a double switched socket as a spur.

I think you mean a DP switch.

Most the info I read about no double sockets was on the iet forum.

Yes, There are several extremely knowledgeable people on there - as you would expect - but there are others too.

Thanks I will purchase a 47mm back box. My understanding is that the ring main will enter switch one, then connect to switch 2 by the neutral and live wires only then again from switch 2 to 3 and finally rejoin the ring circuit from ring 3 with earth.

Yes.

The earth's will be looped to the back box and into their corresponding terminals.

There will be no earth connection on the switches.
Just connect together the earth wires on the ring in and ring out and the earth wires in the socket and three appliance socket cables.
If that is too many for the terminal in the backbox put them all in a connector block with another wire to the back box (and the faceplate if it is metal)

If you are using a grid switch you cannot/ should not connect them as part of a RF the switches are 20a the OPD is 32A
I have a grid arrangement on a 20a 4mm radial supplying 4 non switched sockets.

The current won't actually be going through the 20a switches though. A single grid switch is the same as adding a socket.a socket is classed as a 13a p socket but is still wired into a 32 a RF

If the current is not going through the grid switch how does the appliance get it's power ?

Dave

 

[EFLImpudence]

The appliance will not draw 32A. Hence the 13A socket.

 

[Blueflash]

The current is passing through the switch, yes ?

Dave

 

[EFLImpudence]

Only 13A (or maximum 20A). What about a 13A FCU?

 

[sebastianbawn]

The grid switch to an unswitched socket and 13amp plug is the same as having a fused connection unit, I thino I interpreted that correctly, which is acceptable

Read the regs re accessories permitted for use on a RF

Read the regs re accessories permitted for use on a RF

That's a different reason (if you read it that way) and nothing to do with the current.

 

[Blueflash]

Ah, so there is a reason.

Thanks,

Dave

 

[EFLImpudence]

I said 'if you read it that way'. You cannot be correct, so - no.

whatever, your the man !
