"Locked Rotor Current" also called LRA which stands for Locked Rotor Amps, is commonly found on electric motor nameplates. Locked Rotor essentially means the motor is not turning. The current or amps in this case have to do with the amount of electrical energy required to start the motor. At the ins…

The 'unit' is a measurement of energy used in the
UK for the purpose of billing consumers, and is short for 'Board of
Trade Unit'. An 'unit' is exactly equivalent to the kilowatt hour,
a power of one kilowatt running for one hour. You cannot equate the
unit (energy) with the watt (power).

Connectors- used to attach metallic or non-metallic conduit to the junction or utility boxes. sana makatulong :D
The only time a motor should go into a locked rotor condition is if the motors connected load jams causing the motor to stop turning. At this point if the motor control circuitry is sized to the motor's full load amperage, the high rise in current will trip the motor off line.
On an existing installation make sure that the circuit that you are working on is not energized.

Normally the neutral wire of every circuit is connected to the neutral bus bar in the main breaker panel. Because the neutral bus bar is always connected to ground you should never be able to measure any voltage between the neutral wire and ground. So, if you are measuring 45 to 60 VAC between the…
