Building a new home or commercial property in Pennsylvania is an exciting process, but ensuring the safety and functionality of the electrical system can feel overwhelming. At Thomas Edison Electric, we know that proper electrical inspection is essential to protect your property and meet local code requirements. Whether you’re a homeowner, builder, or property manager, our electrical inspection checklist is designed to help you understand what to expect and how to prepare for a successful inspection.

1. Verify Electrical Panel Installation

The heart of your electrical system, the main electrical panel, must be installed correctly and meet all code requirements. Inspectors will check:

• Proper mounting of the panel.

• Correct labeling of circuits for clarity and compliance.

• Grounding and bonding connections.

• Clearance around the panel for accessibility (minimum 3 feet in front and 30 inches wide).

2. Confirm Proper Wiring Installation

Wiring must be done with precision to ensure safety and efficiency. Inspectors will assess:

• Correct gauge and type of wires are based on the circuit’s amperage.

• Secure anchoring of wires and cables to prevent damage or looseness.

• No signs of frayed, exposed, or improperly connected wires.

• Compliance with National Electrical Code (NEC) standards for wire placement and protection.

3. Check Grounding and Bonding

Grounding protects your electrical system from surges and shocks, while bonding ensures electrical continuity. Ensure that:

• A grounding rod is correctly installed and connected to the main panel.

• Ground fault circuit interrupters (GFCIs) are installed in required areas like kitchens, bathrooms, garages, and outdoor outlets.

• Metal pipes and systems are bonded for safety.

4. Inspect Circuit Breakers and Fuses

Circuit breakers and fuses safeguard your property from electrical overload. The inspection will verify:

• Appropriate amperage ratings for each breaker or fuse.

• Proper installation and functionality of arc fault circuit interrupters (AFCIs) in living spaces.

• The absence of double-tapped breakers unless rated for such use.

5. Test Outlets and Switches

All outlets and switches should be installed correctly and function properly. Inspectors will ensure:

• Outlets are placed according to code (e.g., within 12 feet in living areas and 6 feet of countertops in kitchens).

• Outlets and switches are securely mounted, with no exposed wires.

• GFCI and AFCI outlets operate as intended.

• Outlets are tamper-resistant, particularly in homes.

6. Examine Lighting Fixtures

Lighting installation plays a significant role in safety and functionality. Key areas of focus include:

• Secure mounting of light fixtures.

• Proper connection of wires and insulation within junction boxes.

• Use of the correct bulbs and wattage ratings for each fixture.

• Installation of recessed lighting in compliance with fire safety requirements.

7. Assess HVAC and Appliance Wiring

New construction often includes wiring for HVAC systems, major appliances, and specialty equipment. Inspectors will check:

• Dedicated circuits for heavy appliances like stoves, dryers, and HVAC units.

• Proper connection and labeling of appliance wiring.

• Compliance with manufacturer guidelines for installation.

8. Evaluate Exterior Electrical Components

Outdoor electrical elements must be weatherproof and safe. This includes:

• Installation of weather-resistant outlets with covers.

• Adequate lighting for outdoor areas, stairs, and pathways.

• Properly grounded pool, hot tub, or spa wiring if applicable.

9. Inspect Smoke and Carbon Monoxide Detectors

Safety systems are an essential part of any electrical inspection. Ensure:

• Smoke and carbon monoxide detectors are installed as per code (e.g., one on every floor, in each bedroom, and near sleeping areas).

• Detectors are hardwired with battery backup for reliability.

10. Ensure Compliance with Local Codes and Permits

Each municipality in Pennsylvania may have specific electrical code requirements. It’s essential to:

• Obtain and display all necessary permits before inspection.

• Verify compliance with local codes as well as NEC standards.
