To read electrical system diagrams and schematics properly, the condition or state of each component must first be understood. For

To read and interpret electrical diagrams and schematics, the basic symbols and conventions used in the drawing must be understood.

Unlike the single-phase wiring scheme that must make a provision for a neutral leg and separate ground, the three-phase system

Unlike the single-phase wiring scheme that must make a provision for a neutral leg and separate ground, the three-phase system

The source of single-phase (1φ) power in all facilities is by generation from a single-phase generator or by utilization of

To understand electrical wiring schemes used in power distribution systems, you must be familiar with the following terms. Ampacity –

Within the two basic categories of motor controllers, there are three major types of AC acrossthe-line controllers in use today.

Motor controllers range from a simple toggle switch to a complex system using solenoids, relays, and timers. The basic functions

As we have discussed, circuit breakers may be remotely operated. In order to operate the breakers from a remote location,
