Compressor locked rotor amps are measured with an amp-probe or clip on ampmeter. Lock rotor amps are amps with the rotor not turning/moving, and the winding at ambient temperature. locked rotor amps are X4.5 to X5 times the FLA of motor name plate.

What does LRA stand for on compressors?
LRA stands for Lock Rotor Ampere on compressor and means that it is a high inrush current during starting period of the compressor. Ercona...
What is the average wattage a freezer uses?
Voltage X amps = wats 120 volt freezer drawing 2 amps is 240 watts running note it can take up to 3 to 4 times that to start. you have rla run load amps then you have LRA Lock rotor amps (what it takes to start)
Removing a 1986 celebrity steering wheel lock plate?
To take the lock plate off requires a lock plate spring compressor. With the spring compressor in place and the spring slightly compressed remove the circlip that holds the lock plate on. Then release the spring compressor and the lock plate simply slides off.
Can the bearings in car ac make the engine lock up?

What causes compressor to lock out ina home ac?
what causes compressor lockout in voager rooftop unit.
What does fia stand for in air conditioners?
I think you mean FLA. Sometimes the data plate is worn out or sun faded so it is hard to see. This stands for Full Load Amps ("Full Lock Amp") in refrence to motor/ compressor you are checking.
How do you remove a 1986 celebrity steering wheel lock plate?
Use a spring compressor to push the lock plate down slightly, then remove the circlip that keeps the plate on. Release the spring compressor and the lock plate will come off. Reverse the procedure to reinstall.
Will a heat pump compressor burn out if the circulation fan does not work?
If the fan outside is not running the compressor will overheat and if the fan inside the house is not running the compressor will get liquid refrigerant back to it and lock up! Neither is good for the compressor.
Phase imbalance on three phase compressor Can a phase imbalance cause a compressor to lock up mechanically even if power restored to unit?
yes
What is the ratio between locked rotor current and full load current?
Each motor has a published manufacturer Lock Rotor Amperage (LRA) rating that is used to obtain this ratio. If a manufacturer otained a reading of 100A while bench testing their motor (equipment) at full load, if the motor FLA (Full Load Anps) is 50 amps, the raito LRA to FLA is 2 to 1 or 200%.
What would cause your brake caliber to lock onto your rotor?
Either caliber is bad. or break line is clogged.
