Electric Load Center Costs

The home electric load center is where the circuit breakers are located. It can become necessary to upgrade the load center for more breaker spaces and a higher power rating. 

You will find that the cost to install an average load center upgrade depends upon the power and class ratings, number of breaker spaces, job preparation and special requirements, and the labor rate.

In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
