I haven't seen 575V applied to a 110V motor either. I'll give the workers a little credit. We use two power cords for testing. Three wire SO cord for single phase and a 4 wire for 3 phase. Usually the wiring might have two of nine motor wires swapped. They get confused sometimes with the 230V...
It would be great if there was more accountability and training for production workers and their supervisors. I think they still look at it as if a fuse blows there must have been something wrong with the fuse. No matter how many times I tell them different.
Another problem I have is, I'm the...
Thanks for the comment.
A couple of operators prewire the motors. They wire 2' long SO cords to the motor and strip back the other end. When the motor is installed into the leveler by a different operator, that operator hooks up a power cord from the test panel via insulated alligator clips and...
How would I set up a circuit diagnostic? The operators wire the motors (i.e. 1-line, 2-line, 3-line, 4-7, 5-8, 6-9).
The operators aren't smart enough to do this. Let alone any other wiring. Time is also a restriction. We build dock levelers. We operate the levelers before they ship. What could...
Thanks aolalde.
Do you know where I can find a good cheap breaker for a 1HP motor?
I can get a Square D one for $400. I know it can pay for itself in 6 months, but I might have a problem justifying five of them for one panel to my boss.
The product we build uses hydraulic motors. They can range from 110VAC, 220VAC single and 3 phase, 480VAC, and 575VAC, depending on the customer.
We test these motors on a test panel with a selector switch for the different voltages. They are all 1HP motors. Each voltage has a motor starter and...
