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 hazards. NERC CIP-014 further requires utilities to assess and protect critical transmission infrastructure, including high-voltage switchgear assets. Regular documented inspections reduce unplanned outages, satisfy FERC reliability standards, and extend asset service life.

Industry: Electric Utilities
Frequency: Monthly
Estimated Time: 45-60 minutes
Role: Utility Engineer
Total Items: 36
Compliance: OSHA 29 CFR 1910.269, NFPA 70E-2021 Article 130, NERC CIP-014-3, FERC Order No. 693, DOE Safety Order DOE-O-420.2C

Pre-Inspection Safety & PPE Verification

Confirm all lockout/tagout, arc flash PPE, and work authorization requirements are met before beginning physical inspection.

Has a valid Energized Electrical Work Permit been issued for this inspection?
Is appropriate arc flash PPE selected based on the incident energy analysis for this switchgear?
Have all LOTO procedures been applied per the site energy control plan?
Is the arc flash hazard label present, legible, and current on this switchgear?
Has the inspector confirmed they are a qualified electrical person authorized for this voltage class?

Enclosure & Structural Integrity

Assess the physical condition of the switchgear enclosure, doors, panels, and mounting structures for damage, corrosion, or unauthorized access.

Is the switchgear enclosure free from physical damage, dents, or deformation?
Are all enclosure doors, panels, and covers securely fastened and properly aligned?
Is the enclosure free from corrosion, rust, or moisture ingress?
Are all nameplates, ratings plates, and warning signs intact and legible?
Is the enclosure grounding and bonding connection visually intact with no loose conductors?
Capture a photograph of the switchgear enclosure exterior condition?

Circuit Breaker & Disconnect Switch Condition

Inspect circuit breakers, disconnect switches, and operating mechanisms for proper function, wear, and contamination.

Do all circuit breakers operate smoothly through open and close cycles without binding?
Are breaker trip indicators and position indicators reading correctly and consistently with actual switch state?
Are the breaker contacts and arc chutes free from excessive wear, pitting, or carbon deposits?
Is the SF6 gas pressure (if applicable) within the manufacturer's specified operating range?
Are all racking mechanisms and draw-out rails for withdrawable breakers free from damage and properly lubricated?

Busbar & Insulation Assessment

Evaluate busbars, insulators, and cable terminations for thermal damage, tracking, contamination, and insulation breakdown indicators.

Are busbars free from visible discoloration, heat damage, or signs of arcing?
Are all bus insulators free from cracks, chips, tracking, or contamination?
Are cable terminations and lug connections tight, properly torqued, and free from corrosion?
Have infrared thermography readings been taken and do they show no anomalous hot spots (>10°C delta above ambient)?
Record the maximum temperature reading observed during thermography scan?

Protective Relaying & Control Systems

Verify the condition and operational status of protective relays, control wiring, and SCADA interface equipment.

Are all protective relay status indicators showing normal operation with no fault or alarm flags?
Is control wiring free from chafing, damage, improper terminations, or missing insulation?
Are all relay settings verified against the current approved protection coordination study?
Is the battery backup system for control power showing correct float voltage and no low battery alarms?
Are SCADA communication links and RTU interfaces operational with current data being transmitted?

Environmental Conditions & Housekeeping

Assess switchgear room environment, ventilation, cleanliness, and fire suppression readiness.

Is the switchgear room temperature within the equipment manufacturer's specified operating range?
Is the switchgear area free from combustible materials, debris, and unauthorized stored items?
Is ventilation adequate with air flow unobstructed and cooling fans (if present) operational?
Are fire suppression systems or portable extinguishers present, charged, and within inspection date?
Is access to the switchgear room controlled and logged per the site security plan?

Deficiencies, Corrective Actions & Sign-Off

Document any deficiencies found, corrective actions initiated, and obtain authorized sign-off to close the inspection record.

Were any deficiencies or non-conformances identified during this inspection?
Describe all deficiencies identified and their severity (Minor / Moderate / Critical)?
Have corrective action work orders been created in the CMMS for all identified deficiencies?
Is this switchgear cleared as SAFE TO OPERATE following inspection completion?
Next scheduled inspection date and any special monitoring requirements?
