Electrical panel inspections are the frontline defense against facility fires, equipment damage, and costly
downtime. With electrical failures causing over 50,000 industrial fires annually and accounting for $1.8 billion
in property damage, systematic panel inspections aren't optional—they're essential. Yet studies reveal that 60%
of facilities lack formal electrical inspection programs, leaving critical infrastructure vulnerable to
preventable failures. OXmaint's maintenance management software streamlines electrical inspection workflows with
automated scheduling, digital checklists, and instant work order generation—start your free trial today to protect your facility.

Common Electrical Panel Problems and Warning Signs
Recognizing early warning signs prevents minor issues from becoming catastrophic failures. Train your maintenance
team to identify these common problems during routine inspections. Early detection can prevent 85% of electrical
failures and associated downtime.
Critical
Burning Smell or Smoke
Indicates active arcing or overheating. Immediate shutdown required. Do
not re-energize until inspected.
Action: De-energize immediately, evacuate area
Critical
Visible Arcing or Sparks
Active electrical fault presenting immediate fire and shock hazard. Arc
flash incident risk is high.
Action: Emergency shutdown, qualified repair only
High
Discolored Components
Brown/black discoloration on breakers, bus bars, or wiring indicates
past or ongoing overheating events.
Action: Schedule immediate repair, monitor closely
High
Frequent Breaker Trips
Indicates overloaded circuits, failing breakers, or downstream faults
requiring investigation.
Action: Load analysis and circuit evaluation
Moderate
Missing/Illegible Labels
Creates safety hazards and code violations. Impedes troubleshooting and
emergency response.
Action: Update panel directory, verify circuits
Moderate
Corrosion/Moisture
Reduces connection integrity and insulation effectiveness. Can lead to
ground faults and arcing.
Action: Identify source, clean, apply protection
OXmaint's inspection module includes severity-based escalation workflows. When technicians identify critical
issues, the system automatically alerts supervisors and generates priority work orders. Schedule a demo to see how
automated escalation protects your facility.
Turn Inspections Into Immediate Action
OXmaint automatically converts inspection findings into prioritized work
orders with full documentation, photos, and repair guidance.
Thermal Imaging Best Practices
Infrared thermography is the most effective predictive maintenance tool for electrical systems. Thermal imaging
detects hot spots from loose connections, overloaded circuits, and failing components before they cause
failures. Follow these guidelines for accurate, actionable thermal inspections.
Before Scanning
Ensure minimum 40% load on circuits
Allow 2+ hours under load before scan
Remove panel covers safely (de-energized or qualified personnel)
Calibrate camera to ambient temperature
Document baseline readings
During Scanning
Scan all connections systematically
Compare similar components (phase-to-phase)
Document all anomalies with photos
Note ambient and reference temperatures
Record load conditions during scan
Severity Classification
1-10°C above ref: Monitor closely
11-20°C above ref: Schedule repair
21-40°C above ref: Repair ASAP
>40°C above ref: Immediate action
NFPA 70B Compliance Requirements

Frequently Asked Questions
How often should electrical panels be inspected?
NFPA 70B recommends annual comprehensive inspections at minimum, with quarterly
thermal imaging and monthly visual checks for critical panels. High-demand environments may require more
frequent inspections. OXmaint helps you establish and maintain appropriate inspection schedules—
start your free trial to automate
scheduling.
Who is qualified to inspect electrical panels?
Electrical panel inspections must be performed by qualified electrical workers
with training in electrical safety, arc flash hazards, and proper PPE usage. NFPA 70E and OSHA require
documentation of qualification.
Talk to our team about building qualification tracking into your
inspection program.
What PPE is required for electrical panel inspection?
PPE requirements depend on the arc flash hazard level determined by an arc
flash study. Typical requirements include arc-rated clothing, safety glasses, insulated gloves rated for
the voltage level, and face shields for higher hazard categories. Never open energized panels without
proper PPE.
Can thermal imaging be done on energized panels?
Yes, thermal imaging is most effective on energized panels under load. However,
panel covers must often be removed, which requires proper PPE and safety procedures. Many facilities
install IR viewing windows to allow scanning without cover removal.
Schedule a demo to
learn how OXmaint tracks thermal findings.
How do I document electrical inspections for compliance?
Documentation should include inspection date, inspector name, all findings
(positive and negative), photos of issues, corrective actions taken, and follow-up verification.
OXmaint's digital checklists automatically capture all required information and store it for instant
retrieval during audits—
