411.3.3 omitting an rcd

[Octopus]

I have a dedicated circuit for our fridge freezer - you can't use the pulg unless you pull the fridge out. The circuit is protected by a MCB and there are no labels.

As far as I'm concerned this is OK but under the 18th, as I understand it, this won't be allowed ............... which is daft.

In this mdern world how many languages would the label have to be written in.

At one point I used the MK plugs and sockets with 't' shaped earth pins for dedicated fridge/freezer radials without additional RCD protection, these days though such a circuit could be on an independent RCBO.

You don’t need to label sockets, if their purpose is easily identifiable.
For instance a socket behind a washing machine or other under counter appliance, a socket next to a boiler in an airing cupboard or even a socket next to a TV aerial point.

Read the regulation, pretty sure labelled socket is mentioned in the text.
It’s common sense as if it’s not behind an appliance what’s to inform the user that it’s not rcd protected.
Your example makes sense so in the case of the socket being fed via a DP switch or spur, I would label the switch.

Identifying switches that control under counter appliances is to my mind a very good idea.
However, it’s not something required by BS7671.

Out of interest what installation method did you use to be able to omit the RCD protection?

Common sense. There is a 700mm deep fridge freezer in the way ...

However, when this platform arrived it came with two moulded c form socket outlets and no space for my isolators. It looks a bit like a bird table with a plastic lid. I have therefore had to connect to two socket outlets bringing me under the scope of 411.3.3.

Eh? The unit arrived with two socket outlets fitted to it, presumably these are for the pumps to connect to? I don’t understand what prevented you fitting rotary isolators for the incoming supply to the unit?

I don't understand...what's the freezer got to do with the installation method? Clipped direct, in trunking, buried in wall etc.

So the run from the CU to under the floor is more than 50mm

The run up the wall is less than 50mm (there is about 1 inch from the top of the skirting to the bottom of the socket)

My house, my choice.

But what if you decided to hang a picture just below the socket, behind the freezer?

I was wondering where to hang my miniture picture - what a great suggestion!

 

[lurch]

remove the sockets and put your rotary isolators in and hard wire . . . .
