Electrical Visual Inspection​

Schedule an Evaluation
Electrical Visual Inspection

Electrical systems are the backbone of any facility, powering essential operations across industries. However, faulty wiring, loose connections, and equipment wear and tear can pose serious safety hazards, leading to electrical failures, fires, and costly downtime. 

Regular Electrical Visual Inspections help identify potential risks before they become critical issues, ensuring compliance with safety standards and maintaining the integrity of your electrical infrastructure. 

At C&H Electric, we provide comprehensive Electrical Visual Inspection services to help businesses stay compliant, prevent hazards, and keep their systems running safely and efficiently. 

Why is Electrical Visual Inspection Important?

Regular Electrical Visual Inspections are crucial for:

Preventing Electrical Hazards

Identifies risks such as faulty wiring, overheating, and loose connections before they lead to system failures or fires.

Enhancing Equipment Lifespan

Detects early signs of wear and tear, allowing for proactive maintenance and reducing costly repairs.

Ensuring Compliance

Meets electrical safety standards such as NFPA 70E, and OSHA 1910 avoiding regulatory fines and legal issues.

Minimizing Downtime

Prevents unexpected failures, keeping operations running smoothly without unplanned outages.

Reducing Maintenance Costs

Helps organizations implement predictive maintenance instead of expensive emergency repairs.

Why is It Important?

Our Electrical Visual Inspection process follows a structured approach to assess your facility’s electrical safety and performance:

Step 1: Initial Assessment

  • Review of electrical documentation and previous maintenance records.
  • Discussion of known issues and operational concerns.

Step 2: Physical Inspection of Electrical Systems

  • Examination of wiring, panels, circuit breakers, and grounding systems.
  • Identification of loose connections, overheating, corrosion, and damaged insulation.

Step 3: Documentation & Reporting

  • Detailed inspection report with findings, risk levels, and recommended corrective actions.
  • Compliance verification with NFPA, and OSHA standards.

Step 4: Action Plan for Maintenance & Repairs

• Prioritization of issues based on risk severity.
• Recommendations for repairs, upgrades, or additional testing (e.g., Infrared or Ultrasonic Testing).

Visual Inspection vs. Other Inspection Methods

For comprehensive electrical testing, Visual Inspection and Other Predictive Inspection Methods should be used together to provide a complete assessment of your electrical system’s health.

FeatureVisual InspectionInfrared ThermographyUltrasonic TestingVoltage & Current Analysis
Primary FunctionDetects physical defects, corrosion, insulation wear, Code violationsDetects heat emissions from electrical faults Detects sound emissions from electrical defectsMonitors electrical loads and power quality
Best for DetectingVisible faults like damaged wiring, and grounding issues, and Compliance Issues. Overheating components and load imbalancesArcing, tracking, loose connections, and insulation breakdownsPower fluctuations, harmonics, load imbalances
Detection RangeIdentifies surface-level issues that are visible to the naked eyePrimarily detects surface-level temperature variationsCan detect hidden defects inside switchgear, cables, and panelsMeasures voltage, current flow, and system efficiency
Environmental ImpactWorks in all conditions but limited to visible issuesWorks effectively even in no-contact scenariosWorks effectively even in noisy or enclosed spacesRequires live monitoring for accurate analysis
Equipment RequiredNo special equipment requiredThermal imaging camerasUltrasonic detection toolsPower meters, oscilloscopes
LimitationsCannot detect hidden internal faults or temperature issuesCannot detect electrical discharge faultsCannot detect overheating componentsCannot detect physical defects or insulation wear
Industry Use CasesIdeal for routine safety checks, and compliance auditsBest for identifying already existing temperature issuesIdeal for early fault detection before heat buildup occursBest for identifying harmonics from non-linear loads 

Key Electrical Items you can inspect visually

  • Look for burn marks, discoloration, or corrosion indicating overheating or moisture exposure.
  • Ensure all panel covers are securely in place.
  • Identify loose or exposed wiring that could cause electrical faults.
  • Check for tripped breakers or blown fuses, which may signal overloads or short circuits.
  • Ensure breakers are properly labeled and not obstructed.
  • Look for cracked or damaged breaker casings that could lead to malfunctions.
  • Inspect for frayed, cracked, or exposed insulation, which can lead to short circuits or fires.
  • Look for wire discoloration or burning that may indicate overheating.
  • Check if wires are securely fastened and not excessively bent or pinched
  • Ensure enclosures are properly sealed to prevent dust, moisture, or pest intrusion.
  • Look for rust, corrosion, or physical damage that could compromise electrical safety.
  • Verify that all access covers are securely closed.
  • Check that grounding wires are securely connected and free from corrosion.
  • Ensure grounding rods and bonding jumpers are intact and properly installed.
  • Look for any loose or disconnected grounding conductors that could pose a shock hazard.
  • Ensure outlets and switches are not loose or damaged.
  • Test Ground Fault Circuit Interrupters (GFCIs) to confirm they trip properly.
  • Look for scorch marks or discoloration, which may indicate overheating or arcing.
  • Inspect for burnt-out bulbs, flickering lights, or faulty ballasts.
  • Ensure emergency lighting is operational and properly maintained.
  • Look for exposed wiring or improperly installed fixtures.
  • Check for cuts, frays, or exposed wires that could pose an electrical hazard.
  • Ensure cords are not overloaded or running under carpets, doors, or heavy equipment.
  • Avoid daisy-chaining extension cords, which can lead to overheating.
  • Look for oil leaks, rust, or overheating signs on transformers.
  • Ensure motor housings are clean and free from dust accumulation that can cause overheating.
  • Check for unusual vibrations or sounds, which may indicate internal mechanical or electrical issues.
  • Inspect charging cables for damage, wear, or improper connections.
  • Ensure power supply units are securely mounted and functioning properly.
  • Look for loose connectors or overheating signs at charging ports.

Compliance and Safety Standards

Electrical Visual Inspections are critical for meeting industry safety regulations and avoiding non-compliance penalties.

Key standards include:

NFPA 70E

Electrical safety in the workplace, requiring regular maintenance and hazard assessment.

OSHA 1910

Workplace electrical safety standards, ensuring compliance for key facilities.

At C&H Electric, we ensure full compliance with these standards, keeping your facility safe and regulation ready.
