Electrical Safety Test Load with dielectric and safety tester connected load of 1.75 kW: a worked example in hospital equipment & clinical furniture

Suppose dielectric and safety tester connected load falls to 1.75 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the energy cost of running electrical safety tests on hospital equipment per shift, including ground continuity, leakage current, and dielectric withstand tests required by IEC 60601-1 or NFPA 99.

The inputs for this scenario

  • Dielectric/safety tester connected load: 1.75 kW (the input this scenario stresses; the baseline uses 3.5)
  • Test bench runtime per shift: 6 hr (held at the documented default)
  • Facility electricity rate: 0.12 $ / kWh (held at the documented default)
  • Devices safety-tested per shift: 40 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total test energy used = test station connected load × runtime per shift (kWh).
  • Total test energy used per shift works out to 10.5 kWh at these inputs, and this is the headline figure for the scenario.
  • Total test energy cost per shift works out to 1.26 $ at these inputs.
  • Energy cost per unit tested works out to 0.03 $ / piece at these inputs.
  • Test station hourly energy cost works out to 0.21 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where dielectric and safety tester connected load sits at 3.5 kW and the headline result is 21 kWh, this scenario comes in 50% below the baseline at 10.5 kWh.
  • It computes test-bench energy consumed per shift in kWh, the dollar cost of that energy, and how much of it is attributable to each device safety-tested. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total test energy used per shift: 10.5 kWh (headline result)
