My circuit breaker keeps on turning off my refigerator show caste pastry and my freezer which has ice cream cakes at my work I don't know why in business 30 years first time
Nothing changed. Class ctl panelboard.

Maybe 3 phase and needs load to be checked, could just be a bad breaker?
Are these on 1 circuit?

Old coolers start to draw more amps with age. Have an electrician check to see what each is pulling under full load

They are on 1 circuit and the freezer and the refrigerators are new 3years old if I turn the one refrigerator off its OK but they all have been working fine until know .Do u think it's the braker that is bad?
p.s it's a 2post breaker.
Thank you

You were likely right at or over the maximum rating of the circuit and it is just now beginning to trip. This is normal and common.
Breakers do not trip the moment they exceed their rating. A 20A breaker for instance can run at 23-23 amps for days if not longer before it trips. It's called a trip curve. The higher above the rating the faster it trips.

Did anyone do a calculation when these units were installed to see if the circuit could handle it? I would assume not.

CALL and electrician. He will be able to tel you exactly what is going on.

I would have on separate Circuits, Both kicking in at the same time can easily trip a Breaker.

Agree and think its tie to call a licensed electrician for his on site evaluation of the problem and the fix
