integral fridges

[Steve]

In a shop fit out, with no cables run in plaster etc, all accessible and obvious. The shop fridges and freezers are all integral - they simply plug in and go. Would you supply them via RCBOs?

13A socket outlet?

Well, you could label them as for supply of refigeration equipment only, or fit non-standard plugs and sockets to prevent abuse.

Now you mention it, I am not sure if they are plugged into a 13A or a blue ceeform. I do know they are all single phase and under 3kw, so probably 13a plugs. The sockets are all hidden behind the fascias above the fridges - its all been boxed in to vent the heat to a fan unit which blows it outside. So theres no danger of anything else being plugged into the sockets.

Ceeforms are OK. 16A CPD?

If they're 13A, they really need labelling to comply, even if they're hidden away.

In this case, RCD protection is not required by regulation, but in a shop, with customer contact, you may want the protection.

I think I'd try and keep each fridge on it's own non-RCD circuit. I presume your fridges will be alarmed, so there shouldn't be too much risk of one tripping and going un-noticed.

An RCD isn't really necessary for a fixed appliance like a big fridge.

 

[Steve]

Yes rf they are all networked into an rdm. So is the energy panel. Its getting very high tech now. Soon head office will be able to see all our fridge settings and heating and lighting settings, all via the store broadband line.

Tesco and gateway/somerfield/co op, tend to go for 20 amp radials with 16/20 commando type non rcd, non switched outlets.
There integrals ran at about 14 amp and were not suitable for 13A sockets though
Rcds seem to be quite rare on refridge and we only really see them on the leads to charge the home shopping vans

I don't fit RCD protection... It adds costs for no good reason and risks nuisence tripping for no good reason. I label 13A sockets appropiatly, but I don't there is much need, no one is going to be plugging anything else into socket behind the hoarding!
