As in the past, utility distributors, which tend to have fewer customers and employees than full-line electrical distributors, dominate the list of distributors as ranked by sales-per-employee. The companies here were among those respondents that provided both a 2010 sales number and an employee count in this year's listing. The average sales-per-employee for the 132 companies that provided data for both 2010 sales and number of employees was $624,204.
