Electrical Inspection Checklist for Service Businesses [Free Download]

What is an electrical inspection checklist?

An electrical inspection checklist is a list of tasks and checkpoints that electricians use to examine electrical systems, such as:

• Electrical appliances
• Electrical panels
• Lighting fixtures
• Outdoor electrical components
• Electrical wiring and outlets

The main purpose of a checklist is to confirm that all components of an electrical system are working correctly and safely, and comply with local electrical codes. It helps you identify and address electrical hazards before they become serious issues, improving safety for both the property owner and you and your workers.

Using an inspection checklist helps you maintain high standards, prevent hazards, and ensure your work meets regulatory and quality requirements within the electrical industry. 

Rather than “winging it,” you’ll have a step-by-step guide to perform thorough inspections of residential and commercial properties without missing critical details.

By consistently using a checklist, your electrical business can enhance its reputation by delivering reliable, compliant services.

Benefits of using an inspection checklist

An electrical inspection checklist offers many advantages for you and your clients. Here are some of the benefits:

• Comprehensive inspection: A checklist helps you stay organized, so you don’t overlook any critical areas during an inspection.
• Improves safety: By identifying potential electrical safety risks, a checklist protects both the technician and the people using the system.
• Reduces liability risks: An inspection documented with a thorough checklist can help minimize liability, showing that you followed all necessary procedures.
• Enhances customer trust: Using a structured approach demonstrates your commitment to high standards, building confidence with clients.
• Identifies potential issues before they become major problems: A checklist makes it easier to spot early warning signs, preventing dangerous situations down the road.

Pro Tip: Use job forms in Jobber to create electrical site inspection checklists. When the job is finished, you can share the completed checklist with your customers, so they can see which services were completed during your visit.

When to use an inspection checklist

An inspection checklist can be used in many situations to check that electrical equipment is safe, functional, and compliant. Here are some situations where you should rely on one:

• During initial installations: Whether installing new electrical equipment like lighting systems, outlets, or panels, a checklist ensures all components are properly connected, grounded, and compliant with codes.
• For routine maintenance inspections: Regular maintenance keeps electrical equipment in safe and efficient working condition. A checklist helps you identify wear, damage, or potential hazards like loose connections or overloaded circuits.
• When troubleshooting electrical issues: Flickering lights or outlets that don’t work can be frustrating for clients. Using a checklist allows you to systematically diagnose and fix the issue without overlooking anything.
• Before buying a property: Clients buying a home or commercial space often need a professional inspection to evaluate the condition of the electrical system. A thorough review shows buyers what they’re getting into.
• After renovations or major electrical work: Renovations often involve upgrades or changes to the electrical system. A checklist helps you confirm that all new installations are up to code and function properly.
• In preparation for safety audits: Commercial clients may need an inspection to meet regulatory requirements. A checklist helps their systems pass inspections and remain compliant with safety regulations.

Now that you know the purpose and benefits of using a checklist for residential and commercial properties, it’s time to explore what to include.

What to include in your residential inspection checklist

When performing an electrical inspection in a home, it’s important to focus on everything from general safety standards to specific components like wiring, outlets, and appliances. Below, we’ll break down what to include in a residential checklist you and your workers can use:

General safety and compliance

• Technicians are wearing insulated gloves, flame-resistant clothing, and safety glasses.
• PPE is in good condition and rated for the voltage at hand.
• Hard hats and hearing protection are worn in the appropriate environment.
• Technicians are trained in arc flash safety protocols and proper signage is displayed.
• Technicians are using arc-rated PPE and tools when working near energized components.
• Outlets, panels, and wiring follow National Electrical Code (NEC) guidelines for electrical installation and safety.
• Circuits are properly labeled, and systems are grounded according to NEC standards.
• Circuit breakers and fuses are appropriately rated for the connected loads.
• Inspection reports are complete, accurate, and stored securely for future reference.
• All necessary permits and compliance documents are available and up to date.
• Any repairs, upgrades, or deviations from standard procedures are noted.

Pro Tip: Join the National Electrical Contractors Association (NECA) and find your local chapter. Get safety training and resources to provide better customer service and maintain a safe work environment.

Wires and outlets

• Cords are routed away from walkways to prevent tripping hazards.
• Wires have intact insulation and no exposed conductors.
• Wires are housed in conduits or raceways where necessary to prevent damage.
• Outlets and switches operate correctly and supply power as expected.
• Use a circuit tester to identify issues like reversed polarity or open grounds.
• Feel outlets for excessive heat, which could indicate loose connections or overloading.
• Check for GFCI (Ground Fault Circuit Interrupter) protection in wet areas like kitchens and bathrooms.
• There are no burn marks, cracks, or discoloration on outlets and switches.
• There are no loose connections or missing screws on outlet plates.
• Cords aren’t frayed or pinched, 
• No cords are running under carpets or rugs.
• Cords are routed away from walkways to prevent tripping hazards.

Lighting

• Bulbs match the recommended wattage for each fixture to avoid overheating.
• Non-IC-rated fixtures are kept clear of insulation.
• Dimmer switches operate smoothly without the lights buzzing or flickering.
• There are no loose or faulty connections that may cause flickering.
• Light fixtures have no damage, rust, or loose components.
• Suggest LED upgrades for improved energy efficiency and longevity.

Electrical panel

• The panel is labeled, including an accurate circuit directory.
• There are no signs of corrosion, damage, or rust on the panel.
• Check the panel temperature to detect overheating or potential overloads.
• Test each circuit breaker to confirm it trips properly and resets without any issues.
• Look for breakers that frequently trip or show signs of wear.
• If double-tapped breakers are present, those need to be removed as they’re often not permitted in homes.
• There’s a whole-house surge protector or point-of-use protector. Recommend adding surge protection if none is present.
• Compare the panel’s rated capacity to the current electrical load to avoid overloading.
• Identify panels nearing their limit and recommend upgrades.

Appliances

• High-power appliances use heavy-duty plugs.
• Appliances operate properly. 
• Appliances don’t have any damaged cords or components.
• There are no signs of overheating, such as scorch marks near plugs.
• Major appliances like air conditioners are plugged directly into an outlet rather than into an extension cord. Some appliances (like refrigerators) may, however, use a special appliance extension cord.
• Remind homeowners not to yank cords from the outlets, but instead hold on to the plugs directly.

Electrical fire prevention

• A class C fire extinguisher rated for electrical fires is easily accessible.
• Test all detectors to confirm they sound an alarm. Replace batteries if needed.
• Detectors are installed in key areas like hallways and kitchens.
• Flammable items are stored away from appliances and outlets.
• Check for AFCI (Arc Fault Circuit Interrupter) protection, which is required in many areas of modern homes for fire prevention.
