Pre-Power Panel and Incoming Supply Check

When to use: Before first energization of a control panel, machine electrical system, or incoming supply connection.

Incoming supply review

  • Confirm the intended supply type, voltage, frequency, and phase arrangement
  • Measure incoming voltage and verify it is appropriate for the equipment basis
  • Check for obvious abnormal phase imbalance or upstream wiring irregularity
  • Confirm phase sequence where rotation-sensitive equipment is involved

Upstream protection review

  • Confirm feeder breaker or upstream protective device basis
  • Confirm disconnect suitability for the application
  • Confirm conductor and protection basis have been reviewed together
  • Confirm SCCR context has been reviewed where applicable

Panel inspection before power

  • Perform visual inspection for loose conductors, damaged insulation, or unlanded terminals
  • Confirm major terminations and lugs have been checked against the intended torque basis
  • Confirm no obvious foreign objects, debris, or shipping restraints remain in the enclosure

Grounding and bonding review

  • Confirm the panel frame is bonded as intended
  • Confirm the equipment grounding path is continuous to the facility grounding system
  • Confirm grounding and bonding conductors are landed and identified as intended

Control power and staged energization

  • Confirm the planned first-power sequence before energization
  • Isolate or stage control power where the startup method depends on controlled bring-up
  • Confirm drives, power converters, or sensitive electronics are not enabled prematurely

Stored-energy and insulation awareness

  • Identify whether the system includes VFDs, DC buses, filters, or other stored-energy devices
  • Follow OEM guidance for discharge waiting time and safe verification before contact
  • Review whether insulation-resistance testing is appropriate for the connected equipment before performing it

This checklist does not replace OEM commissioning instructions, site LOTO and electrical safety process, or approved startup method statements.

Trust Boundary — Engineering Judgment Required

This site is an independent educational reference for industrial automation standards. It paraphrases and organizes guidance in original language; it is not a substitute for the official published standards, professional engineering judgment, or legal review, and content has not been independently verified against current published editions.

Items marked Review pending await technical review against the identified edition. Items marked Planned have no reviewed source material behind them. Do not rely on this site for compliance determinations, safety-critical design decisions, or legal interpretation.
