Carla said. “If your meter reads a steady 50 A while running, that’s bad—the rotor is partly locked. If it reads 58 A for a split second and then drops to 11 A, that’s normal start-up.”

Sam tested the compressor. On start-up, he saw a spike for 0.2 seconds, then 11 A steady—but the unit still tripped. He checked the breaker. It was a standard 15 A breaker (not HACR-rated). That 58 A surge, even for a fraction of a second, pushed the magnetic trip in the standard breaker. lra to amps calculator

Carla said, wiping sweat from her brow, “LRA means Locked Rotor Amps. That’s the sudden surge of current the motor draws the instant it tries to start, but the rotor is stuck. RLA is Running Load Amps—what it uses once it’s spinning freely.” Carla said
