To gain information about the electrical load characteristics of farms, a sample of 36 farms was selected for study. Farms were chosen from those making considerable use of electrical energy outside the home and using at least 8,000 kwh of electricity per year. These farms and nine of the homes were metered continuously with recording demand meters for a period of 1 year beginning in July 1954. Records of the current used by some of the farm production appliances were obtained with recording ammeters.

Data from the recording meters were analyzed to show the average load characteristics of individual farms and homes, demand patterns of appliances used in production, coincident demands of farms and estimations of future farm load characteristics.
