Today, I will begin to explain the Electrical Load Classification and Types, this explanation will be as an introduction for beginners in electrical design to know all types of Electrical Loads and their general characteristics. so, other detailed topics will be posted but in Courses

**EE-2 "Basic Electrical design course – Level I "**and

**EE-3 "Basic Electrical design course – Level II"**for explaining design method and design calculations for each electrical load.

__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)

__17- According To Method of Load Reduction / Control__

- Dimmed Electrical Load.
- Shed Electrical Load.
- Shifted Electrical Load.

In the next Topic, I will explain all these

**types of****Electrical Loads**. so, please keep following.
This blog is awesome. It has everything that is required for electrical engineers. I have a question though.

ReplyDeleteI am beginning my career as a building services engineer and am using Dialux. I would like to know, after generating the output from a designed room how to check if the design is right or wrong. Hope you would be able to assist.

Blog Is really awesome with lots of info mainly for electrical engineers

ReplyDeleteThis is supeb . Thank for giving such a wonderfull information

ReplyDeletethanks alot for this information

ReplyDeleteVery useful, Thank you

ReplyDeleteIt's more than just.. Precisely discussed no scope for confusion.

ReplyDeleteThanks

This was really an awesome blog in which I get much information

ReplyDeleteWhat is an example of a VARYING DUTY motor application ? Does say a fountain pump used with a VFD to create special water displays count ? The NEC definition is so broad that it seems any Pump/Fan on a VFD could be classified as such.
