Hello Jim

How many amp breaker is it on?
Hello again
What is th amperage on the side of the motor ?
i believe it should be on a 20 amp breaker
Hello
The compressor get's harder to work over time like your car
have you changed the oil in it ?
You say 15 minimum
if you have 12 or better wire feeding it change the breaker to a 20
Everything get's old and wears just like me lol
I'm sorry if you don't like my answer but if your an electrician why would you put something in at a minimum ??
I always go at least 125% of minimum where did you get your license ?
I'm sorry if it did
But you stated you were an electrician
If something calls for a 15 amp minimum then you should have a 20 or 30 on it
Parts wear and a 3 ho motor on a 15 amp circuit is just not enough you said OEM was cut in at 90 and out was 100 now you say it's 100 what is it ??if this trys to cut in at 100 it will trip
I understand your response
your original was nothing but 100
And i under stand your question why has it been working this long
If your an electrician why not put an amp probe on it and figure it out ?
