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

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

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

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 testRecord 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 checkKeep UPS load step, battery age, bypass status, runtime, voltage, current, alarms, and maintenance owner in one test record.

Assumptions. Balanced load and line-to-line voltage assumptions behind this chart.

The worksheet assumes the load bank, cables, ventilation, controls, and safety plan are suitable for the equipment.
A load-bank step record supports review but does not by itself establish acceptance, maintenance compliance, or return to service.

Code and standard notes. Planning limits that should be checked before final equipment selection.

Use this chart as a maintenance log; verify manufacturer instructions, facility test procedure, OSHA controls, NFPA maintenance practices where adopted, NETA practices where applicable, AHJ expectations, and qualified-person review before acceptance or return to service.

How to use this chart

1Prepare the setup recordRecord equipment rating, load bank ID, cables, ventilation, safety controls, and test owner.

2Log each stepWrite kW, percent load, duration, voltage, current, frequency, temperature, and alarms for each interval.

3Close the actionAssign pass, retest, repair, derate, maintenance, or next-test follow-up.

Worksheet checklist. Record source basis, review gaps, and assumptions before using the chart result.

Capture baselineRecord equipment ID, rating, ambient condition, load-bank setup, and instruments.
Capture sequenceRecord load steps, duration, stabilization, readings, and alarms.
Capture closeoutDocument status, action owner, maintenance note, and next test date.

Common mistakes to avoid. Review these before turning chart current into an equipment decision.

Reporting only final percent load without the step sequence and runtime.
Leaving out voltage, frequency, temperature, or alarm data from the load-bank record.
Calling the test complete without owner, action, and next-date closeout.

Frequently asked questions

These answers explain how to use the chart without turning a quick reference into a final design decision.

How is this different from a load testing chart?

The load testing chart is general. This worksheet is for staged load-bank records with step load, runtime, electrical readings, condition readings, and closeout action.

Why record each load step separately?

A short partial-load step and a stabilized high-load step have different meaning. The sequence and duration need to stay with the result.
