Average Current
To determine if motor current un bal ance is a function of the motor or the power supply:
1. Label the leads and the terminals 1, 2, and 3 respectively.
2. Record the amperage for each lead.
3. Move each lead to the next terminal (1 to 2, 2 to 3, 3 to 1).
4. Again read the amperage of each lead.
5. Move each lead to the next terminal (1 to 3, 2 to 1, 3 to 2).
6. Again read the amperage of each lead.
7. If the unbalance moves with the motor leads, the un bal ance is caused by the mo tor. If the unbalance remains
with the terminals, the un bal ance is in the pow er supply.
8. If the current unbalance exceeds five percent, nui sance tripping or ex ces sive heating will result.
9. Connect leads for the lowest percent of current un bal ance.
