A commercial warehouse has a 1 phase, 3 wire 120V-240V overhead service connection from the utility to the service panel. The client would like to add a sub panel in the same building for additional circuits. Which diagram below depicts the proper grounding and bonding per the NEC.

A single-phase rectifier circuit has a variable inductance L connected in series with a resistor and an ideal diode as shown below. When L is set to 0 the output current wave form is depicted below. If L is increased, what would the current output waveform look like? Answer located in upcoming Volume II of […]
