Before and After Pictures from Seneca County
Electrical Panel Upgrade in Willard, NY

Electrical Panel Upgrade in Willard, NY

Before After
Electrical Panel Upgrade in Willard, NY Electrical Panel Upgrade in Willard, NY

This Willard, NY customer needed a line ran from her electrical panel to her new electric dryer, so she contacted Halco for assistance. Because the customer's existing panel was full, Halco technicians gave her the option of installing a new box or adding a sub panel. Installing a sub panel would require tandem breakers and because the customer had a significant amount of tandem breakers already, this was not the best option. The customer chose to have us upgrade her panel to a new, 30 space 100 amp panel and now she is fully functioning and up to code!
