What does a Professional Electrical Safety Inspection Include?

A professional electrical safety inspection for older homes is a systematic and methodical process that typically takes between one and three hours to complete.

During this evaluation, a licensed electrician performs the following checks:

• Service Entrance Examination: An exterior visual check of the service mast, weatherhead, and meter enclosure to ensure they are secure, sealed, and free of corrosion.
• Interior Panel Inspection: The panel cover is removed to check breaker conditions, wire terminations, and signs of overheating, pitting, or “double-tapped” connections.
• System Testing: Testing of all accessible outlets and switches for correct grounding, polarity, and GFCI protection. It also includes testing all GFCI and AFCI devices in areas like kitchens, bathrooms, and garages.
• Load Calculation: A check to verify that the electrical panel’s capacity can safely handle the household’s actual electrical demand.
• Grounding and Bonding Assessment: A thorough scrutiny of the main grounding system, including the ground rod connection and water pipe bond.
• Advanced Diagnostic Tools: Use of specialized equipment such as thermal imaging cameras to identify overheating components, multimeters, and insulation testers.
• Wiring Evaluation: Specifically looking for outdated systems like knob-and-tube wiring, aluminum branch circuits, or deteriorated insulation that may pose fire or shock hazards.
