A chart of modern electrical symbols

Here’s some modern electrical symbols used frequently by any electrical contractor and homeowners that want to save money by doing their own electrical labor. These include some of the more involved applications that aren’t used in normal residential wiring, but for the most part the symbols listed here are used a lot in electrical home wiring.

Low-voltage and data port network outlets like phone jacks and TV cable jacks are different and so they go in a category called “communications”. You can find the low-voltage symbols

Architects like to put all the blueprint symbols in to make the plans more descriptive. The charts below will help you decipher the outlets as they can be quite difficult to understand sometimes.

If you are planning your own home blueprint, you can use these symbols to indicate what goes where.




***Electrical symbols for outlets***

Most of these outlets are common in residential wiring. There are dedicated outlets for single appliances like clothes dryers and ovens that have their own specific outlets.

Remember, things like water heaters and HVAC systems are hard-wired meaning they don’t have outlets, but are wired directly into the appliance and are usually encased in a protective shielding as it comes out of the wall.

It’s important to note that this list is not exhaustive by any means. There are many newer symbols that are used because of newer types of electronic and electrical devices. Always check with your local Electrical inspector to get the most current plans and codes in your area.

I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.

Thank you,

I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
