RE: [GrizHFMinimill] tripping circuit breakers



Hello Dennis,
 
Welcome to the group.
 
More information would be helpful. Here is what I would like to know before commenting.
 
How old is the electrical wiring in the house? I ask because if it is a really old house it might not be grounded properly. I've seen some houses that had the electrical wiring "upgraded" by a non-professional who didn't really know what they were doing when they added new circuits. I love the houses where there is new wiring along with old original knob & tube wiring.
 
How long have you lived in this house? i.e. are you familiar with the electrical circuit history of the house?
 
Have you tried plugging the mill into another circuit? If you did, does the kitchen circuit breaker still trip?
 
I'm not sure if this will tell you anything or not but, you might try one of those little plug in circuit testers with the LED lights on them to detect incorrect wiring.

Subject: [GrizHFMinimill] tripping circuit breakers

 

Hi folks.  I have just joined this group my name is Dennis.  I just purchased a Harbor Freight mini mill three days ago from Tried and True Tools in Fridley Minnesota.  It is used but looks like new.  I have used a mini lathe for a couple of years and thought it about time to get a mill too.  I have a problem that seems unusual to me any way.  I tried a few simple cuts the first two days while waiting for some tooling and accessories from Little Machine Shop to arrive and everything was fine.  But today while running the mill a circuit breaker kept tripping.  But not on the circuit that the mill is on but one of the kitchen circuits. The circuit in my shop that the mill was running on never tripped.  I unplugged everything that was on the kitchen line except the refrigerator and the breaker tripped only when the mill was running.  The mill has been unplugged now for several hours and the kitchen breaker has not tripped.  Does anyone have any idea as to what might be happening?


Dennis
