New Builds: New homes should be inspected shortly after construction is completed, even though they are more likely to meet current safety codes. It’s essential to verify that everything was installed correctly.
Commercial Buildings: Businesses and industrial settings should have their electrical systems inspected at least once a year. This is especially important in workplaces with high electrical demands, machinery, or heavy equipment.
After Significant Events: Any time there is a significant event—such as a power surge, a storm with lightning, or a building renovation—an inspection should be conducted to ensure that no damage has occurred to the electrical system.

Key Components to Inspect in an Electrical System

Electrical systems are complex and involve several components that should be checked regularly. Here’s a breakdown of the major components to inspect during an electrical inspection.

1. Main Electrical Panel

The electrical panel, also known as the breaker panel or fuse box, is the heart of an electrical system. It distributes electricity to the various circuits in your home or business. When inspecting the electrical panel, check for the following:

Tripped Circuit Breakers: Breakers that trip regularly could indicate an overloaded circuit or a problem with the wiring. Ensure the breakers reset properly and don’t feel hot to the touch.
Rust or Corrosion: Corrosion or rust inside the panel could be a sign of moisture buildup, which may cause short circuits or even fires.
Signs of Overheating: If there’s discoloration, melted wires, or a burning smell coming from the panel, it may indicate overheating, which is a significant fire hazard.
Outdated Fuses or Breakers: Older panels may have fuses or outdated breakers that don’t meet modern safety standards. These should be replaced during an inspection.
Loose Connections: Loose connections can cause arcing, which can lead to electrical fires. Ensure all connections are secure.

2. Wiring

Wiring is one of the most crucial aspects of electrical safety. Faulty or outdated wiring can cause a variety of problems. When inspecting the wiring:

Check for Frayed or Exposed Wires: Exposed wires pose a serious risk of electric shock or fire. Replace or repair any damaged wires.
Inspect the Insulation: The insulation around the wires should be intact. If the insulation is brittle or cracked, the wires could be exposed to potential damage.
Proper Grounding: Ensure that all electrical circuits are properly grounded. Grounding protects against electrical shocks and prevents electrical surges.
Check for Overloaded Circuits: Each circuit should have a specific amperage limit. Overloading circuits can lead to overheating and fire. Ensure that no circuit is drawing more power than it’s rated to handle.

3. Outlets and Switches

Outlets and switches are the points of access for electricity. They should be checked regularly to ensure they’re functioning correctly. When inspecting:

Check for Loose or Warm Outlets: Loose outlets can cause poor connections and potentially lead to electrical fires. Warm outlets may indicate overloading or faulty wiring.
Ground Fault Circuit Interrupter (GFCI) Outlets: In areas where water is present (kitchens, bathrooms, basements), GFCI outlets should be installed. These outlets will automatically shut off power if they detect an imbalance in current, reducing the risk of electrical shock. Test GFCIs regularly to ensure they’re working.
Check for Exposed Wires in the Outlet Box: Exposed wires can create shock hazards or short circuits. Ensure that all wiring is properly secured and covered.
Test Switches: Switches should operate smoothly and should not feel hot to the touch. Flickering lights when using a switch could indicate wiring problems or a faulty switch.

4. Light Fixtures

Light fixtures should be inspected for safety and functionality. Look for:

Burnt Out Bulbs: Replace any burnt-out bulbs. This might sound simple, but if bulbs burn out repeatedly, it could indicate an issue with the fixture or the electrical circuit.
Excessive Heat: Light fixtures that become unusually hot could indicate improper installation or that the fixture is not compatible with the wattage of the light bulb.
Check for Loose Wiring: Ensure that the wiring in the light fixtures is secure and properly connected.

5. Extension Cords and Power Strips

Extension cords and power strips are often used to power multiple devices, but they can present significant safety hazards if not used correctly. During an inspection, check:

Overloaded Power Strips: Avoid overloading power strips, as they can easily overheat. Ensure that power strips are used within their rated capacity and that the circuit is not overloaded.
Damaged Cords: Check extension cords and power strips for damage, such as fraying or exposed wires. These can lead to electrical shocks or fires.
Proper Use: Extension cords and power strips should not be used as permanent solutions. They should only be used temporarily and never be daisy-chained (plugging one power strip into another).

6. Appliances

Electrical appliances, especially those with older components, should be inspected regularly to prevent malfunctions.

Check for Frayed or Exposed Wires: Any appliance with damaged wiring should be repaired or replaced immediately.
Proper Functioning: Appliances should work smoothly without any signs of overheating, excessive noise, or strange smells.
Ensure Correct Voltage: Ensure that appliances are being used with the correct voltage. Using appliances with the wrong voltage can damage the appliance or create a fire hazard.

7. Smoke Detectors and Carbon Monoxide Detectors

Although not strictly part of the electrical system, smoke detectors and carbon monoxide detectors are essential for safety. These devices should be inspected during any electrical inspection:

Test Detectors Regularly: Test smoke and carbon monoxide detectors at least once a month. Replace the batteries at least once a year and replace the entire unit every 10 years.
Ensure Proper Placement: Smoke detectors should be installed in every bedroom, hallway, and on every level of your home.
