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.
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
Receptacles / General / Small Appliances Load.
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.
Future Electrical Loads (Electrical Loads Growth).
New Electrical Loads (Additional Electrical Loads).
7- According To Load Operation Time
Continuous 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.
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
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)
14- According To Unity Electrical Load Units
Unity Electrical Load in VA/M2.
Unity Electrical Load in VA/Ft2.
Unity Electrical Load in VA/Linear Foot.
15- According To Electrical Loads Operation Coincidence
Non-Coincident Electrical Loads.
Coincident Electrical Loads.
16- According To Electrical Loads Usage Method
Fixed In Place Loads.
17- According To Method of Load Reduction / Control
Dimmed Electrical Load.
Shed Electrical Load.
Shifted Electrical Load.

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.
