anyone know why an ari compressor would suddenly start poping breakers?..some times it works for days sometimes it pops it every time it kicks back on

doesnt mater what breaker its pluged into
if breaker is kicked on off rapidly 5-15 times air compressor will restart and work fine
 
Did you say it was tripping different breakers or same breaker from different outlets? Supect motor or compressor pump is going out I have repaced 100s of pumps for the problem.. BUT if it is just one CB I have replaced a lot of them.. is it 110? do you have any higher current outlets. This is a std 12 to 15 amp

this is a 20 amp NEMA 5-20R

This receptacle will also accept the 15A/125V 2-wire or 3-wire, male plug above.

If you have one it should allow more current w/o triping
 
its poping any breaker i put it on..currently on a 20amp breaker ....i supose i could flip the switch on the motor to 230 and change the pig tail and see if the problem goes away but id rather not mess with that

sooooo any thoughts?..originaly i thought it was haveing a problem with my ultra heavy duty extension cord but its doing this plugged directly into the wall and on any breaker i put it on ..at first i thought it was the house breakers being the problem as there old and somewhat intolerant of voltage spikes..however with the new shop wireing its still doing it..the colder it is in the shop the more it pops em
 
Inductive motor? Starters getting weak more than likely, go to 220 it will use less power and start easier.
 
Have you put an amp probe on it to see what the pull is on startup, might be a bad start cap or the windings are going south. I would think it's the cap based on it not happening every time, and the temp having an effect. if you have it set for low voltage, and it is a dual voltage motor, try it on hight voltage, it will pull less amperage. Also feel the breaker and see if it is getting warm, that may indicate a weak breaker.
 
well i dont have an amp probe...but i do know that most of the time it would dim lights if it was on a 15 amp braker and even sometimes on a 20 amp

currently its on a 20 amp all by itself and ive swaped in 4 identical breakers with the same results ...

whats this "starter" you speak of?..i have quite an understanding of elec motors but ive never seen one with a switch setup on it like this
 
I'm assuming it's single phase. It will have a start capacator or a mechanical start switch inside the motor.Start windings generally pull more amperage to get the motor spinning, once up to speed, the start switch will drop out and the run windings will take over to keep the motor spinning. A start capacator is usually used with an electronic start switch to start the motor in the proper direction.
 
Should have 10 weight in it unless its been removed and replaced with the wrong stuff, see how thick it looks before you start it and after it cycles a few times.
 
does the motor humm real loud????? could be the relief valve- motor is trying to start up under load- this will cause it to draw lots of amps and pop the breaker


2 cents!!
