Backup Generator FAQ
+Do I need an electrician AND a generator dealer in Centennial, Colorado?
Often one firm handles both, but the electrical side (ATS, panel, grounding, permit) must be performed by a licensed electrician in Centennial, Colorado. Many dealers sub the gas plumbing separately.
+Service-rated vs non-service-rated ATS in Centennial, Colorado — which?
Service-rated ATS lets you eliminate the main breaker and is preferred for whole-home installs in Centennial, Colorado. Non-service-rated is fine for sub-panel / essentials configurations.
+How long does a backup generator install take in Centennial, Colorado?
Permit + utility coordination is usually 2–4 weeks. On-site install in Centennial, Colorado is typically 1–2 days for the pad, gas, ATS, and panel work, plus a commissioning visit.
+Do I need a permit for a standby generator in Centennial, Colorado?
Yes — Centennial, Colorado jurisdictions require electrical (and usually gas / mechanical) permits for any permanent standby. Your installer pulls them and coordinates inspection.
