About Us

Mission Electric Supply was founded in 1975 and operates two locations:  Corporate office and a warehouse in Temecula, CA plus a second location near the coastline in Carlsbad, CA. These two locations uniquely position Mission Electric Supply to support the greater Southern California basin from San Diego to Los Angeles and points beyond. For over 37 years Mission Electric Supply has been supporting small to medium sized businesses and contractors with quality electrical components and value-added consulting services. While anyone can sell something to a customer, Mission takes great pride in assisting the customer with product selection decisions. Don't know what you need? Great! Tell us the operating parameters and we'll take it from there. 

With over a million dollars worth of inventory in stock, Mission has the ability to fulfill most customer needs immediately.
