Check amp on each leg.....
Ah.... got an amp meter.... how do I check amp on each leg?
How do I set the meter?
Where do I connect/touch the probes?
Off the 3 fuses in the box going to the panel in the pics?
Where does the other probe connect/touch to?
Should the motor be Gisholt motor be running or just the Rotary?
Daryl,
As much iron as you are acquiring lately may I make a suggestion? You might be able to do it with a regular “Lead Type Meter” but it’s a little tricky, amps is like flow in hydraulics, so it always has to be measured in series only! If it hooks directly across the supply lines it will blow the protection fuses, if it has them, and maybe damage the meter! I would suggest you either borrow or buy a “clamp on AC Ammeter” The AC only ones are not a whole pile of money, home depot and lowes have them, maybe around $69, with them there is a small circle type clamp that opens up on the end and you just set the scale to ac amps, , and close the loop around each wire feeding the motor one at a time, and read the amps. In the contactors we have at work we test monthly, we leave a little extra wire in the panels so it is easy to put the clamp amp meter onto them. It really only takes maybe 20 seconds and tells you a lot!
The regular amp scales on a general purpose millimeters, usually only go to 10 amps, maybe 20, and if you read the instructions, it is only meant to be on there a very short amount of time, (duty cycle). So when your motor starts it will be way over the meter rating! They are designed more for like testing amps on stuff like, car stereos, cb’s, fog lites, and stuff like that.
