Abstract :
A report of a committee of the Association of Edison Illuminating Companies presented in September, 1923, makes available information concerning the number of lamps and appliances in dwellings in the northeastern part of the country as ascertained through surveys conducted in 1921 and 1922. 1497 residences were surveyed in 1921 and 5015 were surveyed in 1922. The surveys were made in five cities in 1921 and in eight cities in 1922. In each year approximately 100 central station employes visited dwellings and inspected the electrical equipment for this purpose. In addition to noting the number, rating and condition of all lamps and appliances, these men, in conference with householders, estimated the hours use throughout the year for each lamp and appliance. In 1922 graphic meters were installed in more than 100 dwellings chosen as being representative of the whole number surveyed, and records were obtained showing the actual consumption by lamps and by each kind of electrical appliance in these residences during a week in May.
