Abstract
The history and development of the permission granted in the National Electrical Code to group motors on a single branch circuit is reviewed. The interpretation placed on the pertinent sections by code-making authorities and the testing of controls for such use is discussed, and several needed improvements are suggested if this installation practice is to continue to be expanded.
