"JJC Electric wired our new hot tub with a dedicated 50-amp GFCI circuit and installed the disconnect switch exactly where the inspector wanted it. Passed inspection first try. Professional and by the book."
"Had a whole-house Generac generator installed by JJC Electric. The crew handled everything — concrete pad, gas line coordination, transfer switch, and the final hookup. We lost power twice since then and the generator kicked on instantly both times."
