Standby Generator Inspection Logger
NFPA 110-style weekly/monthly genset checks — fluids, battery, block heater, transfer switch, fuel and exercise results; offline route log.
New generator set inspection
NFPA 110: weekly inspection, monthly exercise under load (30 min); diesel fuel testing annually.
Field guide: Standby Generator Inspection Logger
Standby generators fail to start for boring reasons in a predictable order: dead or under-floated batteries first (the leading cause in every failure survey), then fuel problems (water and microbial growth in stored diesel), then someone having left the control switch in OFF after a service visit. The NFPA 110 weekly walk this logger encodes is short precisely because it targets that order — switch in AUTO, charger floating, block warm, fluids up, tank full, no leaks.
The exercise field records what only a loaded run can prove: that the engine starts, takes load and holds it. Running unloaded ('exercise' that never touches the transfer switch) wet-stacks diesels and proves little — which is why the monthly NFPA 110 exercise wants 30 minutes under load. Per-site logs export to the compliance file that AHJs and insurers ask for after the outage that mattered.
Field tips
- Touch the block on every visit — a cold block in winter means the heater failed and the next start is in doubt regardless of everything else.
- Glance in the fuel filter bowl: visible water means the tank has more; schedule polishing before it becomes a mid-outage shutdown.
- After ANY service visit, verify AUTO before leaving site — 'left in OFF' is the most preventable failure in the genre.

Frequently asked questions
What does NFPA 110 actually require weekly vs monthly?+
Weekly: a documented inspection (fluids, battery/charger, fuel, switch position, general condition) — no run required. Monthly: exercise under available load for 30 minutes (Level 1 systems per the standard's tables). Annually and beyond: load bank tests where building load is insufficient, plus fuel testing for stored diesel.
Why do generator batteries fail so often?+
They sit at float charge in temperature swings doing nothing — ideal aging conditions — and the first deep demand in months is a cold-start crank. Survey after survey puts batteries at 35–45% of start failures. The fix is dated replacement cycles (3–5 years) and the charger checks this log captures weekly.
What goes wrong with stored diesel?+
Water condenses in tanks, microbes grow at the fuel/water interface, and modern ULSD oxidizes faster than legacy fuel. The results clog filters exactly when the engine first works hard. Annual fuel testing (per NFPA 110 8.3.8) and polishing programs exist for this; a wet filter bowl on rounds is the early field warning.
What is wet stacking?+
Diesels run lightly loaded don't reach full combustion temperature; unburnt fuel and soot accumulate in the exhaust ('wet stacking'), fouling injectors and turbo. Chronic unloaded exercising causes it — hence the standard's insistence on load. Black drips at exhaust joints in your walkdown are the visible symptom.
