Residential Electrical Inspection Checklist
As a homeowner, you must ensure the safety of your electrical system, before even consulting an expert for inspection purposes.
While it is best to trust in the hands of professional electricians, you can still perform basic residential electrical maintenance to identify any immediate concerns for your electrical system.
Here are the key areas to assess:
Wires and Outlets:
- Are all wires properly covered to prevent exposed wiring?
- Do all outlets and light switches function properly, with no buzzing/crackling noises, broken covers, or discoloration?
- Do the outlets feel cool to the touch?
- Are all wires free of damage, such as frayed or broken parts?
- Are there any cords that could be pinched by doors, windows, or furniture?
- Are the cords free of nails or staples?
- Do you use surge protectors to safeguard electronic devices?
- Do all lightbulbs have the appropriate wattage for each fixture?
- Is there a safe gap between lamps/light fixtures and combustible objects?
- Is there a problem with lights dimming or flickering frequently?
- Have the light fixtures been replaced or upgraded as needed?
- Is the electrical panel up to date?
- Is the electrical panel’s cover cool to the touch?
- Are there any tripped circuits?
- Is surge suppression implemented throughout the home to protect against power surges?
- Are unused appliances unplugged to avoid wasting electricity?
- Are all appliances in good functioning order?
- Are major appliances (such as the refrigerator or stove) plugged directly into wall outlets?
- Is at least one multi-purpose fire extinguisher readily available inside the house?
- Are all smoke detectors and carbon monoxide alarms working properly?

- If there is electrical equipment near water (e.g., swimming pool or hot tub), is it properly protected and plugged into Ground Fault Circuit Interrupter (GFCI) outlets?
Note that this checklist serves only as an initial assessment; to fully ensure the safety of your residential electrical system it is wise to seek professional services from a licensed electrician.
Commercial Electrical Inspection Checklist
Electrical inspections for commercial properties are essential in meeting the safety requirements outlined by the National Electrical Code (NEC).
Below are the main areas typically reviewed during a commercial electrical inspection:
- Are the installations up to NEC standards?
- Are installation instructions followed, and are materials and equipment appropriately labeled?
Current Ratings and Openings:
- Do the interrupting current and short-circuit current ratings meet acceptable levels for the installation’s conditions?
- Are all vacant spaces properly closed?
Contamination and Damage:
- Is there any contamination as a result of using foreign materials?
- Is there anything that needs to be repaired or replaced?
Mounting and Ventilation:
- Are electrical components appropriately installed and ventilated?
Terminations and Splices:
- Do terminations and splices have the required temperature, usage, and electrical ratings?
- Are there adequate enclosure markers and ratings in the surrounding environment?
Clearances and Directories:
- Is there sufficient headroom and operating clearance around the equipment?
- Are circuit directories for switchboards, panel boards, and other comparable equipment available?
In addition to these general areas, specific categories within the NEC may be included, such as:
- Wiring methods and devices
- Branch circuits
- Grounding and bonding
- Dwelling units
- Special occupancies
- Emergency standby systems
- Fire pumps
While these questions give a general framework for commercial electrical inspections, the specifics may vary depending on local legislation and the type of electrical installation in your business. It’s always a good idea to obtain professional advice to ensure that you’re following all local codes and regulations.
