Electrical Panel Inspection Checklist [FREE PDF]

Electrical panel inspections are required under NFPA 70 (National Electrical Code) and OSHA 29 CFR 1910.303 to ensure that distribution equipment is correctly installed, labeled, protected, and maintained in a safe condition. Defective or improperly maintained electrical panels are a leading cause of electrical fires, equipment damage, and fatal electrocutions in industrial and commercial facilities. Routine inspections verify breaker integrity, proper grounding, adequate working clearance, and

Industry: Facility Management
Frequency: Annually
Estimated Time: 30-45 minutes
Role: Electrician
Total Items: 38
Compliance: NFPA 70 NEC Article 110.26 (Working Space Requirements), NFPA 70 NEC Article 408 (Switchboards, Switchgear, and Panelboards), NFPA 70E-2021 Article 130.5 (Arc Flash Risk Assessment), OSHA 29 CFR 1910.303 (General Requirements for Electrical Installations), OSHA 29 CFR 1910.147 (Control of Hazardous Energy - LOTO)

Panel Identification & Documentation

Confirm that the panel is properly identified, documented, and has required labeling in place.

Is the panel clearly identified with a permanent label showing voltage, amperage, and panel designation?
Is a complete and accurate circuit directory posted inside the panel door with all circuits labeled?
Is an arc flash warning label affixed to the panel exterior meeting NFPA 70E and NEC 110.16 requirements?
Are the panel manufacturer, model number, and ampere rating visible on the nameplate?
Photograph the panel exterior and circuit directory for the inspection record.

Working Clearance & Physical Access

Verify that required electrical working clearances are maintained and the panel is accessible.

Is a minimum 36-inch working clearance maintained in front of the panel (or greater per voltage class)?
Is the working space in front of the panel free from stored materials, equipment, or obstructions?
Is the headroom clearance in the working space at least 6.5 feet or equal to the height of the equipment, whichever is greater?
Is the panel room or enclosure adequately illuminated for safe working conditions?
Is the panel room or enclosure secured against unauthorized access with a lock or access control?
What is the approximate measured working clearance in front of the panel?

Panel Enclosure Physical Condition

Inspect the panel enclosure for physical damage, moisture, corrosion, and integrity of covers.

Is the panel enclosure free from physical damage, dents, corrosion, rust, or unauthorized modifications?
Is the panel cover / door fully intact, properly hinged, and does it close securely with no missing knockouts?
Is there any evidence of moisture, condensation, or water infiltration inside the panel?
Is the panel free from evidence of overheating, scorch marks, or burn discoloration on interior surfaces or conductors?
Photograph the panel interior, documenting any deficiencies found.

Circuit Breakers & Overcurrent Protection

Evaluate the condition, rating, and proper installation of circuit breakers and fuses.

Are all circuit breakers of a type approved for use with the panelboard (listed and labeled by a NRTL)?
Are all circuit breakers properly rated and do none exceed the panelboard's ampere interrupting capacity (AIC) rating?
Are all breaker slots occupied with either an active breaker or a listed filler/blank plate (no open spaces)?
Are any double-tapped breakers (multiple conductors under a single terminal not rated for it) observed?
Do breakers that are in the ON position respond properly and show no signs of physical damage or failure to hold?
Is the main disconnect breaker or main breaker present, functional, and within the panel's ampacity rating?

Wiring, Conductors & Connections

Inspect conductor sizing, insulation, connection integrity, and wiring methods within the panel.

Are all conductors properly sized for their overcurrent protection device per NEC ampacity tables?
Is all conductor insulation inside the panel free from cracking, fraying, melting, abrasion, or physical damage?
Are all terminal connections tight with no evidence of loose wiring, arcing, or discoloration at terminations?
Is wiring neatly routed within the panel gutter space with conductors not exceeding the permitted fill?
Are conductors entering the panel protected by appropriate bushings or fittings at all knockouts?

Grounding & Bonding

Verify that grounding and bonding connections are properly installed and intact within the panel.

Is the equipment grounding conductor (EGC) bus bar present, properly bonded, and all EGC connections secure?
In the service entrance panel only: is the neutral-to-ground bond (main bonding jumper) present and properly installed?
In sub-panels: are the neutral and ground buses separated with neutral isolated from the enclosure?
Is the grounding electrode conductor (GEC) visible, intact, and properly connected to the ground bus without splices?
Are all metallic conduits, raceways, and enclosures bonded to the panel grounding system?

LOTO & Safe Work Compliance

Confirm that lockout/tagout procedures and safe work practices are established for this panel.

Is a written lockout/tagout (LOTO) procedure specific to this panel available and posted or accessible to workers?
Does the panel main disconnect or individual breakers have hasp provisions for lockout?
Are lockout devices (hasps, breaker lockouts, tags) stored and accessible near or at the panel?
Has the responsible maintenance supervisor reviewed and signed off on this panel inspection?
List all deficiencies identified during this inspection, corrective actions required, and target completion dates.
Photograph any deficiencies identified that require corrective action.
