re: [GrizHFMinimill] tripping circuit breakers



Does this happen when you start the mill or has it been running for a while?
 
I assume kitchen is on circuit A
Shop on circuit B
 
BTW, usually fridge should be on a circuit by itself.
 
Here is a leap of imagination:
 
As mill starts it draws a lot of amps - this causes a brown out on your main panel - a voltage drop - if your kitchen was running close to capacity & had fridge turn on - another motor - the lower voltage would cause the fridge motor to draw more amps... now if for some reason you got a non-standard instantaneous breaker on circuit A it would trip.

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
