Q:

What is a three-phase electrical wiring diagram?

A:

A three-phase electrical wiring diagram is a clear, visual representation of a common method of power generation and distribution. Three-phase electrical wiring is the most common means of distributing alternating-current power on power grids world-wide.

A pictorial diagram is a simplified graphical representation of the components of the circuit, and a schematic diagram uses standardized symbols. Both types of diagrams depict the connections and parts of the circuit such as wires, power source and signal connections, but do not show the components' specific layout. Circuit diagrams are used for the design, construction and maintenance of electrical equipment. Though the symbols for electrical components have gone through many iterations over time, they are now largely standardized internationally.

    Why is electrical grounding important?

    A:

    Electrical grounding reduces the risk of severe electrical shock from uninsulated metal components inside of electrical devices, appliances and power tools. When a grounded system is secured properly, the leaking current, known as the fault current, is transferred harmlessly. This type of grounding is common in the manufacturing industry and prevents hazardous static charges from accumulating.
