Commercial Generator Service and Maintenance
Monthly exercise and inspection, annual service, transfer switch testing, load bank coordination and storm-season readiness for standby generators at commercial and multifamily buildings in Nassau and Suffolk.
A standby generator that has not been exercised, serviced and tested under load is a guess, not a backup. NFPA 110 sets out a schedule of weekly inspections, monthly tests under load and annual service that keeps the guess out of it. No Shorts Electric maintains commercial generators and transfer switches across Nassau and western Suffolk and installs new units where a building needs one.
What the service covers
- Monthly exercise and inspection: start, run under building load where the transfer switch allows, check fluids, battery, charger, block heater and alarms, and log the result.
- Annual service: oil and filter, coolant, fuel system, belts and hoses, battery load test and a full control panel check.
- Automatic transfer switch inspection and testing, including the transfer and retransfer sequence.
- Load bank testing arranged when the monthly test cannot reach the load the standard requires.
- Storm-season readiness check before the fall, so the unit is ready when Long Island loses power.
- Commercial generator installation and replacement, with permits, PSEG coordination and inspection.
Records
Every test and service visit produces a written record kept for the building and sent to you. Healthcare facilities and buildings with life-safety loads need these records for inspections and surveys; everyone else needs them the first time the unit fails.
