Frequently asked questions
What's the difference between 208Y/120 and 480Y/277 service? +
208Y/120 is common for smaller commercial spaces (bakeries, small restaurants). 480Y/277 powers larger facilities (industrial, big retail). Voltage supports larger motors and reduces wire costs for long-distance runs. We engineer the right service based on your equipment load.
How long does 3-phase service installation take? +
New 3-phase service from utility coordination to final inspection: 3–6 weeks (utility may take 2–4 weeks). Switchgear and feeder install: 1–2 days. We manage permitting and Georgia Power coordination so you don't have to.
Does Georgia Power charge more for 3-phase than single-phase? +
Usually no; 3-phase rates are often cheaper per kWh than single-phase for large users. Demand charges depend on peak load. We run a load study, show you the cost difference, and help you decide if upgrading to 3-phase saves money.
