What Happens During a Residential Electrical Inspection?

Checking the Electrical Panel

Most inspections start at the main service panel. This box acts as the control center for the electrical system. After opening the cover, the inspector looks at the breakers, the wiring, and the grounding. They scan for rust, corrosion, and loose connections that can lead to heat buildup. They also verify that each breaker is sized correctly for the wire it serves. If a breaker has a rating that is too high, it may not trip during a fault, and that can lead to melted insulation or a fire. If the rating is too low, it could trip without a real issue. The inspector may also check how neat the wiring looks. A tidy layout reduces the chance of crossed circuits or short connections. If you recently upgraded anything or added a new appliance, they will confirm that the panel can handle the extra load. A home that’s been running on an older system may need a service upgrade to meet today’s demand for air conditioners, chargers, and entertainment systems.

Testing Outlets and Switches

Next, the inspector checks outlets and switches throughout the house. Bedrooms, kitchens, bathrooms, and outdoor areas are included in this part of the inspection. The electrician in Highlands Ranch uses a tester to see if each outlet is grounded and wired correctly. Sometimes the hot and neutral wires are placed on the wrong terminals. The outlet still delivers power, but the chance of electrical shock rises. In kitchens, bathrooms, and outdoor areas, the inspector confirms that GFCI outlets are installed. A GFCI cuts power right away if it detects a current leak. If a GFCI does not trip when tested, it should be replaced. Switches are also examined for proper grounding and smooth operation. Flickering, buzzing, or loose plates can point to trouble behind the wall. The inspector may also use a voltage tester to confirm that the circuit is carrying power safely.

Inspecting Wiring and Connections

Once outlets and switches are checked, attention turns to the wiring behind them. This step can reveal whether the home’s system was installed correctly or if past repairs were done safely. The inspector looks for exposed or damaged wires in basements, attics, and crawl spaces. Rodents, moisture, and age can all wear down insulation, leaving bare copper that poses a shock or fire risk. Older homes sometimes used aluminum wiring. It can relax at the terminals because it expands under heat, which may lead to loose connections. If needed, the inspector will recommend the correct connectors or a rewiring plan. They will also follow each visible junction box and confirm that all splices are enclosed with a cover. Open or hidden splices are a safety concern because they bypass protection and make future issues harder to catch. If the home has an addition or remodel, the inspector checks the wiring in both sections to make sure the gauge and style are the same. Mismatched wiring creates resistance and leads to uneven current flow.

Evaluating Fixtures and Grounding Systems

Every light fixture, ceiling fan, and appliance that connects to the system must be properly grounded and supported. The inspector checks that each fixture has a secure mount and that its wiring is intact. A loose connection can cause arcing, and that leads to heat and carbon buildup on the terminals. The inspector reviews outdoor lighting and looks at any garages or detached structures that have electrical service. Exterior wiring must run inside conduit and be sealed to protect it from moisture. A good electrical inspection checks that weatherproof covers and seals are in place. Grounding and bonding are another major focus. The inspector ensures that the main system connects to a grounding rod or water pipe and that all metal parts are bonded together. This connection allows fault currents to travel safely into the earth instead of through your home. If your home includes surge protection, that device will be tested as part of this process.

What the Report Includes

At the end of the visit, the inspector prepares a report that shows what they checked and what needs attention. The report includes photos, notes, and clear recommendations for electrical repair services or upgrades. You will see any safety concerns, code issues, or areas that could be improved. It also shows whether the panel has enough capacity, if outlets meet safety standards, and whether the grounding system is complete. Parts that are wearing out, like breakers or light fixtures, will be listed so you can plan ahead. The documentation is useful when planning renovations, selling a home, or working with insurance. It proves that your system was evaluated by a professional and that you took steps to maintain a safe electrical service.

When to Schedule an Inspection

Most homeowners schedule a full inspection before buying or selling property. It is also a good idea to schedule an inspection after a major renovation, an appliance upgrade, or a surge event like a lightning strike. If lights flicker, breakers trip again and again, or a wall near an outlet feels warm, call for help. Even newer homes benefit from periodic inspections. Construction errors can stay hidden for years when shortcuts are made behind drywall. An inspection gives you clear proof that everything is up to code. It also shows whether the system has enough capacity for new appliances or upgrades.
