HP motor with a motor start code of M.

 

 

 

 

 

 

 

Volts = 230

HP = 1/4 Using Table, Code M results in kVA/HP = 11.2

11.2 x 1/4 x 1000

= 12.2 A

Starting the motor requires 12.2 amperes.

To find starting amperage:

Step 1: Find code and use table to find kVA/HP. If code is not listed, multiply running amperage by six to find starting amperage.

Step 2: Find Motor HP and Volts.

Step 3: Determine starting amper- age (see example).

Welding generator amperage out- put must be at least twice the motor’s running amperage.

10-9. How Much Power Can Generator Supply?

1Limit Load To 90% Of Generator Output

Always start non-resistive (motor) loads in order from largest to small- est, and add resistive loads last.

2 5 Second Rule

If motor does not start within 5 seconds, turn off power to prevent motor damage. Motor requires more power than generator can supply.
