    The images below show some of the pages within the download. There are formulas for calculating voltages and wattage which are important for large appliances if you need to calculate current for breakers.

    Most of the brain work for calculating cable sizes and breaker sizes has already been done though. That is what the local codes are for. Electrical inspectors will help you make sure that you have all the right components in place before they turn the power on.
