Electrical Switchgear Inspection Checklist [FREE PDF]

Electrical switchgear inspections are mandated under OSHA 29 CFR 1910.269 and NFPA 70E to protect workers from arc flash, shock, and equipment failure in high-voltage environments. NERC CIP-014 further requires utilities to assess and protect critical transmission infrastructure, including switchgear assets. Regular documented inspections reduce unplanned outages, extend equipment life, and demonstrate compliance during FERC and state regulatory audits.

Pre-Inspection Safety & PPE Verification

Confirm all safety prerequisites and personal protective equipment are in place before approaching energized switchgear.

Has a job hazard analysis (JHA) been completed and reviewed by all personnel?
Are all personnel wearing appropriate arc-flash rated PPE for the incident energy level?
Has an energized electrical work permit been issued and signed where required?
Are appropriate lockout/tagout (LOTO) procedures applied for de-energized components?
Is a safety observer or standby personnel present for this inspection?

Enclosure & Exterior Condition

Evaluate the physical integrity of the switchgear enclosure, doors, gaskets, and external hardware.

Is the switchgear enclosure free of physical damage, dents, corrosion, or unauthorized openings?
Are all doors, panels, and covers securely latched or bolted and showing no signs of warping?
Are door gaskets and seals intact with no signs of deterioration or gaps?
Are arc flash and high-voltage warning labels legible and properly affixed to all compartments?
Is the area around the switchgear clear of combustible materials, debris, and standing water?
Please upload a photo of the switchgear enclosure exterior?

Bus Bar & Connection Integrity

Inspect bus bars, insulators, and electrical connections for signs of overheating, oxidation, or mechanical looseness.

Are bus bars free of discoloration, hotspots, or signs of overheating from previous events?
Are all bus bar connections and bolted joints torqued to manufacturer specifications?
Are phase bus insulators free of cracks, tracking marks, or carbon deposits?
Has thermal infrared scanning been performed on bus connections within the past 12 months?
What is the measured ambient temperature inside the switchgear enclosure?

Circuit Breakers & Switching Devices

Assess the operational condition, mechanical integrity, and trip mechanism function of all breakers and switches.

Are all circuit breakers operating smoothly with no evidence of binding or mechanical resistance?
Have breaker trip mechanisms and close/open operations been tested per the maintenance schedule?
Are breaker contact wear indicators within acceptable limits per manufacturer specifications?
Are arc chutes and arc flash barriers intact with no cracking, chips, or carbon deposits?
Are position indicators and status lights on all breakers functioning correctly?
How many breakers in this section are currently flagged for maintenance or replacement?

Protective Relays & Control Systems

Verify proper calibration, wiring, and functional status of protective relays and associated control circuitry.

Are all protective relays displaying correct status indications with no fault or alarm flags?
Are relay calibration dates current and within the required testing interval?
Are control wiring and terminal blocks free of fraying, loose connections, or insulation damage?
Is the battery backup / DC control power supply voltage within the required operating range?
Are SCADA and remote monitoring communications for this switchgear section functioning correctly?

Grounding & Bonding Systems

Confirm the integrity of equipment grounding conductors, ground buses, and bonding connections throughout the switchgear assembly.

Is the main ground bus conductor securely attached and free of corrosion or mechanical damage?
Are all equipment bonding jumpers continuous, properly sized, and securely connected?
Has ground resistance testing been performed and are values within acceptable thresholds?
Are temporary protective grounds (TPGs) available and in serviceable condition at this location?

Ventilation, Cooling & Environmental Controls

Inspect switchgear room environmental conditions, ventilation systems, and SF6 gas monitoring where applicable.

Is the switchgear room ventilation system operating effectively with no blocked vents or failed fans?
For SF6-insulated switchgear, is the gas pressure within the manufacturer's rated operating range?
Are SF6 gas leak detectors functional and displaying no alarm conditions?
Is the switchgear room free of moisture infiltration, water staining, or condensation on equipment?
Are fire suppression systems in the switchgear room operational and current on inspection tags?

Documentation & Corrective Actions

Record findings, deficiencies identified, and required follow-up actions for regulatory documentation and asset management.

Have all deficiencies identified during this inspection been documented with asset tags and descriptions?
Have corrective maintenance work orders been generated for all identified deficiencies?
What is the overall condition rating of this switchgear unit?
Please provide any additional observations or notes not captured in the checklist above?
Please upload a photo of the completed inspection tag or logbook entry?
