    Residential calculation

    I am trying to learn how to do residential calculations and how or why to use optional method. Does any one know of a free website to learn how to do this.

    Use the examples in annex D in the back of your code book. They are the best reference that I know of for this.

    Thank you for the link. Is these some where that gives practice load test calculations. Like if I wanted to work one out by hand and be able to check if I am right.

    Mike holts website has a free spreadsheet for download for residential calculations. I haven't used it in a while so I couldn't tell you what limitations it has (no optional calc, auto-derate of neutral, no commercial consideration), but it's great to check your answers to when doing the calcs by hand.
