Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a ...

Group motor protection as described in NFPA 70, the U. S. National Electrical Code (NEC) Article 430.53 lets two or more motors be protected by the same overcurrent device as long as the installation ...

When an overload device sized in accordance with 430.32(A)(1) and (B)(1) is not sufficient to start the motor, higher size sensing elements shall be permitted if the trip current does not exceed ____% ...

Enhancing motor-drive apps with added safety, the ACPL-785J isolation amplifiers include both short-circuit and overload detection and allow direct measurement of motor phase currents in power ...

Circuit protection has proven useful, but meeting the increasingly sophisticated industrial and commercial requirements can be a challenge. An overload or short circuit in a fuse or mini circuit ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...

Overloading electrical circuits is easier than you may think, especially around the holidays. At best, overloading the circuit is inconvenient, but it can also be dangerous. So, if you see the warning ...
