Commercial fridges (ring)

The apprentice · Jul 15, 2022

Hi there as detailed in the picture I have a lot of fridges and freezers to be installed within a commercial environment as of running the cabling for rings etc iam either going to need obviously a few ring mains but my question is when the compressor all kick in at the same time will this need to be done via a contactor or just multiple ring mains

Are these remote units in other words is the refrigeration within the units or in a separate plant room.

If they are split units the outdoor unit, servicing multiple fridges, will most probably be inverted anyway.

I would only run 1 or 2 fridges on each circuit, if a breaker trips, you can at least move the products into the remaining units instead of having half or all of them off at the same time.

I'd be looking for manufacturer data, they'll most likely have a minimum device size and type specified.

You can work your circuits from there.

Without this info I'm guessing.

If they plug in to typical 13A sockets then can you make sure those are accessible so if one is playing up or suspect it can be switched off and isolated (as per @James suggestion for limiting fault impact).
