Frequently asked questions about EPSS Acceptance

What do Level, Type and Class mean in NFPA 110?

Level reflects the consequence of failure (Level 1 where failure could result in loss of life or serious injury), Type is the maximum time to restore power (Type 10 = 10 seconds), and Class is the minimum run time without refueling (Class 2 = 2 hours). The acceptance test proves the installed system meets its designation.

What does the NFPA 110 acceptance test include?

A simulated primary power failure with verification of start and transfer within the Type time, a cool-down of at least 5 minutes, and a 2-hour full-load test at 100% of nameplate rating using building load supplemented by a load bank as needed.

How is this different from the electrical installation certificate?

The NEC electrical installation (wiring, transfer switch, grounding) is documented on the generator and transfer switch installation certificate. This report covers the mechanical installation and the NFPA 110 acceptance test.
