You can't measure an RLA. It is determined by the factory that manufactured the compressor. To answer your other question, a 230 volt load is actually using both legs as part of the circuit, so you can measure either leg with a current meter but there is no need to add them up.
The company known as Gray Indiana is located at414 Murphy RdColfax, LA 71417There phone number is 318-627-5782There are no cities in Indiana named Gray.There IS a Gray RLA Airport, near Fairland, IN
First, check the nameplate on the motor. The FLA or full load amperage is the required start up current and is typically 125-150 % higher than the running load amperage (RLA). So a current draw of 39.5 while starting would be normal for a motor drawing 25 A in run mode.You don't need any calculations. If the stated RLA is close to 25 A and you're drawing 25 A then the motor is fine. As long as you're supplying the correct full voltage required by the motor, it will operate at "full capacity". There are numerous formulas for motors. I would need to know the motor's horsepower, voltage, whether it's single or three phase and its stated efficiency (EFF on the nameplate), the FLA and RLA to tell you if the motor is running properly or if it's going bad.
