Welcome! You have arrived at the web's most complete electrical design resource site. This site has been designed for electrical engineers, electricians, students and anyone else that is interested in learning about how to design electrical engineering systems. Here you will find numerous resources involved in the electrical design process. The best part is that it is all free for you to read and download.

New! Due to the large number of requests, I am offering electrical design consulting services.Click here to learn more.

If you are a student this site will serve as a foundation to grow your understanding of how electricity has been harnessed to power the world we live in. For background on the history of electricity, click here to jump to that page. Or, check out the Ohm's Law and Circuits sections. These will help you understand the basics of how electrical systems are designed.



If you happen to be an electrician or electrical engineer, this site will serve to assist you in the design process. The sample electrical riser diagrams and electrical panel schedules can give you guidance when calculating equipment loads and sizing the distribution.





Is the local AHJ requiring a voltage drop calculation? Click here to jump to the Voltage Drop Calculator which is based on the National Electrical Code and can be easily printed for submission. Or are you looking for a handy guide to sizing conductors that can be taken to a jobsite for reference? Go to the Conductor Sizes page for a table that thoroughly details sizes required by NEC for amperages as low as 20A to as high as 1600A.





The philosophy of this site is to empower you with both real world knowledge and theory of electrical engineering which can be used during both design and construction of a project.
