Default Throwing my breaker with new equipment

I just got a three door commercial beverage cooler to use as a keg cooler, bottle storage and lager chamber, supercool. I got it running for a few minutes, but it keeps throwing the circuit breaker built into the outlet in my garage. Can't get it to run for more than a few minutes...what can I do to keep this running uninterrupted?

What size CB and what is the current draw of the unit? Also does the CB have GFCI protection?

I'd say this needs to be on a dedicated 20A circuit.
That is the way we wire break rooms.

Have you looked at the condenser coils? It may have multiple refrigerant units underneath. As the temp raises on the high side of the refrigerant circuit, pressure also raises and the compressor has to work harder.

This implies that it's a gfci receptacle and it is tripping. If that's the case I would recommend inspecting the cooler's wiring for damaged insulation, poor ground connections or other abnormalities. Also try a a receptacle on a different circuit. As well as a dedicated circuit.

Thanks for the replies! CB and GFCI are literally Chinese to me tho. Sounds like I may need an expert to look at it.

Circuit Breaker - an electrical device in the main or sub electrical panel associated with an electrical circuit (receptacles, lights, etc.)

Ground Fault Circuit Interrupter - an electrical device that interrupts a circuit when it senses a ground fault. It can be tested by pressing a test button integrated into the device. It would then be reset with its reset button. It can take the form of a circuit breaker in a panel or a receptacle (which is what I assumed you have). Code requires them in garages, kitchens and bathrooms circuits. GFCI receptacles can be wired to protect downstream, non-gfci receptacles.

Unless you have a friend that's an expert, you might consider a few of the ideas presented to you in this thread before you pay$$ an expert to take a look at it.

Though the photo is a bit murky, it appears to be a BeverageAir product. Likely the MMR72 or close to it. The MMR72 is spec'd at about a 10amp current draw. It shouldn't trip a circuit breaker by itself.


A few simpler questions, if you want to try to troubleshoot your problem:

Are there other large appliances in the garage that may be on the same electrical circuit?

Is the cooler plugged into a receptacle that has a test and reset button? If yes, then it is a GFCI receptacle. Is this what is tripping?

Assuming a GFCI receptacle:
Is anything else plugged into it? If yes, try unplugging the other item.
When the test button is pressed are there other receptacles in the garage that lose power? If yes, what's plugged into those receptacles?

Nice. The cooler is not plugged into a receptacle with the test/reset button, but I do have a keggerator on the same circuit in the garage. When the cooler loses power, so does the keggerator. When I press the reset button, they both come back on but only for a few minutes... This circuit is on a 15amp breaker (main switchboard).

theres your problem...
refrigeration really needs to be separate circuits because they draw quite a bit of power... take off your kegerator and see if it does the same thing... if it does try it on a dedicated 20amp and cross fingers... those true units take a bit of power due to their size

I agree. That thing is a beast. It most likely needs 20a dedicated.

Cheers!
