Load Bank Test Record Worksheet Chart
Use this worksheet after a load-testing or generator calculator result to record load-bank setup, step sequence, percent load, kW, voltage, current, frequency, runtime, temperature, alarms, and corrective action.
Quick reference table
A load bank test record worksheet is a step-by-step test log. It is narrower than a general load testing chart because it focuses on staged load-bank runs for generators, UPS systems, and standby equipment.
Load bank step record
| Step field | Record on worksheet | Review use |
|---|---|---|
| Setup | Equipment ID, load bank ID, cables, ventilation | Confirms test setup context |
| Step load | kW, percent load, duration | Separates warm-up, intermediate, and final steps |
| Electrical readings | Voltage, current, frequency, power factor if used | Checks stability under load |
| Condition readings | Temperature, fuel, alarms, vibration, noise | Captures equipment response |
| Closeout | Pass, retest, derate, repair, owner, next date | Turns readings into an action record |
Load bank handoff
| Related page | Use this worksheet for | Do not duplicate |
|---|---|---|
| Load testing chart | Staged load-bank sequence and readings | General equipment test summary |
| Generator sizing chart | Rated kW, step load, fuel and frequency notes | Generator sizing selection |
| UPS backup time chart | UPS load step, battery status, bypass or shutdown note | Runtime estimate alone |
How to use this chart
Prepare the setup record
Record equipment rating, load bank ID, cables, ventilation, safety controls, and test owner.
Log each step
Write kW, percent load, duration, voltage, current, frequency, temperature, and alarms for each interval.
Close the action
Assign pass, retest, repair, derate, maintenance, or next-test follow-up.
Formula basis
Percent load = applied load kW / rated equipment kW x 100.
- Applied load kW is the load-bank step used during the interval.
- Rated equipment kW is the generator, UPS, or equipment test basis.
- Runtime records how long each load step was held.
- Voltage, current, frequency, temperature, and alarms decide whether the step is acceptable for review.
Worked examples
Standby generator annual test
Record 25%, 50%, 75%, and 100% load steps, voltage, current, frequency, engine temperature, alarms, runtime, fuel note, and follow-up action.
UPS discharge and load-bank check
Keep UPS load step, battery age, bypass status, runtime, voltage, current, alarms, and maintenance owner in one test record.
