Charger Cabinet Assembly Time at 14% assembly support allowance: a worked example

This scenario runs the charger cabinet assembly time calculation on the strong side: 14% assembly support allowance, with every other input held at its documented default. a production manager needs to know whether charger cabinet assembly fits the available shift labor

The inputs for this scenario

  • Charger cabinets to assemble: 32 cabinets (unchanged)
  • Cabinet assembly rate: 4 cabinets / hr (unchanged)
  • Assembly support allowance: 14 % (raised for this scenario; the documented default is 12)

Working through the calculation

  • Applying the documented formula (Base cabinet assembly hours = charger cabinets to assemble รท cabinet assembly rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.12 hr for required charger cabinet assembly hours, the number this scenario is built around.
  • At this operating point the engine returns 8 hr for base cabinet assembly hours.
  • At this operating point the engine returns 14 % for assembly support allowance.
  • At this operating point the engine returns 4 cabinets / hr for cabinet assembly rate.

How this compares with the baseline

  • Against the tool's baseline example, where assembly support allowance sits at 12% and the headline result is 8.96 hr, this scenario comes in 1.79% above the baseline at 9.12 hr.
  • Use it when scheduling an EVSE build run, sizing the assembly crew, or quoting a delivery date for a batch of charger cabinets. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance
