The specifics of this are found in Article 430 of the National Electrical Code.
Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.
Call the police. Patrol cars carry equipment to open locked doors.
Locked rotor current is the current drawn by a motor when the rotor is prevented from turning, usually occurring during a fault condition. Starting current, on the other hand, is the initial surge of current required to start the motor and overcome inertia. Locked rotor current is typically higher than starting current.
"Full locked amperage" or "Full locked start-up Amperage" is what I was taught.
Running current. The locked rotor amps are only seen at initial start up which only lasts a fraction of a second to one or two seconds.
consults with authorized workers and appropriate points of contact to ensure that the machinery and equipment can and will be locked out and tagged out properly
You need to first know the wattage of the motor and locked rotor current can be tested at a lab only
This is the removal and installation of a rear shock in a Camaro there might be some differences
"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 instant the motor is switched on, it is not turning, and draws the maximum current. As the motor starts to turn, the current goes down. This required energy is much greater than the Full Load Amps or Running Amps, which is the current drawn when the motor is running at normal speed under full load. The current required to start the motor will depend on the type of motor as well as the specified design voltage required for the motor, typically the higher the voltage, the lower the required amperage or current. The term also applies to equipment such as Air Conditioners which have an enclosed motor inside the compressor, as well as the condenser fan(s) etc. Depending on the type of motor, LR current can be anywhere from 3 to 8 times the normal running current, also called RLA, or running load amps.
yes
an acceptable method of communicating to affected persons when (date, time of shutdown) the machinery and equipment is to be locked out and tagged out and again when the machinery and equipment is to be returned to service.
