"Ariel installed 50 amp inlet to my breaker box for portable generator. He completely cleaned up the breaker box. Separated rooms to different breakers so I can turn off rooms i don't use. He was extremely thorough in his work. Upon finishing installation, Ariel stayed on his own time and explained everything i needed to know about using generator and which breakers to use if i have a power outage. He was very knowledgeable and made sure i understood before he would leave. I highly recommend ACG based on my experience with his work ethic. Thank you Ariel!"
