[Part 1 begins a look at how to interface with some common robotics-type sensors and actuators, and how these can be tied into an example system (in this case, the author's E-2 Autonomous Submarine ...

Isolating problems in the control circuitIn Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic ...

Load switches with controlled limited turn-on times, launched from several peer points on two wires, can significantly save energy. Such switches can be used at the entrance to the premises, passage ...

All questions and answers are based on the 2011 NEC. Q. What is the Code rule for motor control circuit overcurrent protection? A. Motor control conductors that aren’t tapped from the branch circuit ...
