If we get a breaker trip, which doesn't happen often, people switch it back on, and if necessary plug the fridge freezer in somewhere else. It doesn't seem to be a significant issue. If you only had the fridge on the circuit it would take far longer to realise power was lost.

** IME, it is common practice here ( Australia ) to put fridges and freezers on a dedicated circuit since they often have high levels of leakage to earth.


I'm not aware of ours suffering that. Why do they have alot of leakage?


That circuit would also not be under control on an ELCB or similar.

Otherwise, the ELCB needs to be set at an hazardous trip current to avoid outages and food spoilage.

No, it's because their refrigerators are made by Lucas!



Prince of Darkness, yes.



And he prefers to live in England, thank God!


Lucas electrics weren't the ultimate, but weren't too bad really. And it was a long time ago.

I've never heard of Lucas fridges.

If it trips with only the fridge or freezer on the circuit, resetting the breaker wouldn't do any good, if a few hundred Watt load is tripping a 20A breaker.

Indeed, if the fridge trips the breaker then it is broken...shorted
motor or similar. Not going to work any better on another outlet!
Whereas sometimes you can pop a breaker and not realize it.

One can always get a battery powered fridge alarm - I have it on our
deep freeze, but my wife doesn't want it on the house fridge as she
doesn't like the look of it...

And don't overlook the fact that the breaker could be SNAFU.
They're not designed to be switched off and on again -- over and over.

Or you can make Pimpom's blackout alarm (link is still good):

Who does that to a fridge or freezer? I've only shut off one breaker to kill a fridge that had a damaged thermostat and was it icing over. It was my dad's house, and he was going to stay at my sister's so there was no reason to let the compressor run 24/7/365.25 days a rear. I need to haul it to the landfill for it can be sent for recycling.

How long can the piezo sound when powered by a 1000ufd cap? Perhaps a
small battery would be a good addition...
