Electrical Load Classification and Types

[elec master]

Electrical Load Definition:

the Electrical Load is The part or component in a circuit that converts electricity into light, heat, or mechanical motion. Examples of loads are a light bulb, resistor, or motor.

another definition:

If an electric circuit has a well-defined output terminal, the circuit connected to this terminal (or its input impedance) is the load.(see fig.1)

Electrical Load Classification and Types:

the electrical loads can be classified into various categories according to various factors as follows:

1- According To Load Nature-1

Resistive Electrical Loads.
Capacitive Electrical Loads.
Inductive Electrical Loads.
Combination Electrical Loads.

2- According To Load Nature-2

Linear Electrical Load.
None-Linear Electrical Load.

3- According To Load Function

Lighting Load.
Receptacles / General / Small Appliances Load.
Power Loads.

4- According To Load Consumer Category

Residential Electrical Loads (Dwelling Loads).
Commercial Electrical Loads.
Industrial Electrical Loads.
Municipal / Governmental Electrical Loads (Street Lighting, Power Required For Water Supply and Drainage Purposes, Irrigation Loads And Traction Loads).

5- According To Load Grouping

Individual Loads (Single Load).
Load Centers (Area Loads).

6- According To Load Planning

Existing Electrical Loads.

Thanks for sharing. I would like to add that over the years, electrical utilities have built classifications of home loads into a small number of representative classes.
