Switchgear Assembly Hours at 12% setup, wiring, and test allowance: a worked example

Push setup, wiring, and test allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a switchgear lineup changes section count, build rate, or test allowance and you want to see the impact on assembly hours.

The inputs for this scenario

  • Switchgear sections to assemble: 120 sections (unchanged)
  • Assembly completion rate: 12 sections / hr (unchanged)
  • Setup, wiring, and test allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base switchgear assembly hours = switchgear sections to assemble รท assembly completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required switchgear assembly hours, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base switchgear assembly hours.
  • At this operating point the engine returns 12 % for setup, wiring, and test allowance applied.
  • At this operating point the engine returns 12 pieces / min for assembly completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, wiring, and test allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It computes required switchgear assembly hours by dividing sections by the assembly completion rate and then padding for setup, wiring, and test time. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required switchgear assembly hours: 11.2 hr (headline result)
  • Base switchgear assembly hours: 10 hr
  • Setup, wiring, and test allowance applied: 12 %
  • Assembly completion rate: 12 pieces / min
