Granite State Electricians did an excellent job! The electricians installed a new breaker panel and special circuits with twist lock and quad outlets for my workshop, installed a GFCI breaker for an outlet in one of my bathrooms and connected the outlets in my kitchen to a GFCI outlet as well. They also converted my three-prong dryer plug to four prong and fixed an open wire in my garage. They were professional, efficient and everything works great 🙂
