Can this be used to control a cooker plate?

http://www.tlc-direct.co.uk/Main_Index/Wiring_Accessories_Menu_Index/RCD_Protected_Range/RCD_Protected_Range_2/index.html

There is no RCD protection at the board. Client wants a new cooker which is under 13Amps.

Wondered if this could be used as the isolating switch above the worktop with the cooker plate going below? If not, what are alternatives?

Thank you.

Sure you can, if it's an oven and not a complete cooker..... By cooker plate, do you mean a CCU (cooker connection unit)?? If so, again yes!!

but any new wiring chased into wall would require RCD (if its before the spur)

Hi Andy

The intention is to spur from the RM to the RCD FCU, then chase into wall below worktop and connect to CCU (as Larnacamum said).

My concern was that there isn't an actual switch to turn the power off to the cooker, you'd have to press the "test" button which isn't ideal!

Would it be best to have the RCD FCU, an isolating switch, THEN go down to the CCU below worktop?

That should work Nat, so long as the new cabling is protected by RCD you should be fine.

Yes, but you're then going to have a DSO, RCD FCU and a switch for the cooker all in a row - it's not going to look great and the kitchen's fairly small!

 

[Zeespark]

Can you not hide some of it in a cupboard somewhere?

RCD spur can be used as isolator

Question is, why do you want to install an RCD?

 

[avinalarf]

I thought I had to if altering a circuit which isn't currently protected!

this perhaps?

Only circuits of special locations require RCD protection.

How will you protect the cable that spurs from the ring to the RCD FCU, or will it be surface run?

 

[Sidewinder]

Spin,

As I see it this will be existing or surface?

If not then as you say any chased cables upstream of this RCD would need protection by RCD also.

 

[spinlondon]

Of course there is the option of using cable with an earthed metallic sheath.

 

[Sidewinder]

^ True!

again, already answered

Are you under the impression that placing accessories in rows, somehow protects the cables?

 

[Andy™]

Are you under the impression that placing accessories in rows, somehow protects the cables?

if they are in a row, then they would be next to each other. in which case, no chased cables, no need for RCD.

 

[spinlondon]

I don't believe I've ever come across accessories that can butt up against each other, so as the cables don't have to jump a gap to reach the next back box.

 

[Zeespark]

A dual accessory box would work, you can even get a double and single together now.
