Many visitors came to this blog looking for a schematic diagram for a simple house wiring. The original post, House electrical wiring, symbols and checking, is too long. Many readers clicked away. My guess is that they cannot find the schematic drawing. So I decided to separate it into a small article, here. ====== RELATED ARTICLES: | House electrical symbols | Simple house electrical layout |

If you are looking for a simple list of house electrical symbols, below is one. If you are surprised at how short the list it, then please know that this list of electrical symbols has been used in this country for thirty or maybe forty years.
