    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.

    Non-Continuous Electrical Loads.
    Duty, Intermittent Electrical Loads.
    Duty, Periodic Electrical Loads.
    Duty, Short-Time Electrical Loads.
    Duty, Varying Electrical Loads.

    8- According To Load Importance

    Vital Electrical Loads (Life Safety Electrical Loads).
    Essential Electrical Loads (Emergency Electrical Loads).
    Non-Essential Electrical Loads (Normal Electrical Loads).

    9- According To Load /phase distribution

    Balanced Electrical Loads.
    Non-Balanced Electrical Loads.
    Neutral load.
    Line to neutral load.

    10- According to number of Electrical Loads phases

    Single phase Electrical Loads.
    Three phase Electrical Loads.

    11- According to actual Electrical Loads value

    Nameplate load.
    Full load.
    Percent of full load.
    No load (Open Circuit).

    12- According to Electrical Loads unit

    Electrical Loads in KVA.
    Electrical Loads in KW.
    Electrical Loads in HP.

    13- According to Electrical Loads diversity (simultaneous and non- simultaneous operation)

    Connected Load.
    Demand Load.

    14- According To Unity Electrical Load Units

    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.
