What a Home Electrical Inspection Includes

A home’s electrical system is its silent, hidden nervous system. It is responsible for powering everything, from the refrigerator to the furnace that keeps you warm during an Idaho winter. Unlike plumbing or roofing issues, electrical problems are often hidden behind walls and inside panel boxes, remaining undetected until a catastrophic failure occurs. A flickering light, a warm outlet, or a buzzing sound from the breaker box are all signs that an unseen danger may be lurking. An electrical inspection is the only way to get a professional, comprehensive look at the health and safety of this critical system.

Many homeowners only consider an electrical inspection when buying or selling a home, but it is a necessary preventative measure for any property over twenty years old or one planning a major remodel. The demands placed on a home’s wiring have changed drastically over the decades. What was once a safe system can quickly become an overloaded hazard with the addition of modern appliances, computers, and high efficiency HVAC units.

A professional electrical inspection is an investment in safety. It serves as a shield against potential fires, shock hazards, and expensive, unexpected system failures. It is a detailed assessment designed to check compliance with the National Electrical Code and identify outdated wiring, improper installation techniques, and capacity issues. Understanding what this inspection includes highlights its value as a tool for proactive home management in Idaho Falls.

A Deep Dive into the Electrical Panel

The electrical panel, often called the breaker box, is the absolute heart of your home’s electrical system. It is the first and most critical component inspected by an electrician. The inspector opens the panel, safely turning off power to remove the dead front cover, to visually examine the internal components. This process requires a licensed professional due to the high voltage present.

The first step is checking the circuit breakers. The electrician verifies that every breaker is properly sized for the wiring it protects. A breaker that is too large will fail to trip when a fault occurs, allowing the wire to overheat and cause a fire. The panel is checked for hazardous conditions like “double taps,” where two separate wires are improperly connected to a single breaker terminal. This is a common and dangerous shortcut that leads to loose connections and arcing.

Furthermore, the electrician assesses the panel’s overall condition. They look for signs of rust, corrosion, or water damage, which can lead to rapid failure. They also identify any outdated or recalled panel brands, such as Federal Pacific Electric or Zinsco panels, which are known to have failure rates that pose a significant fire risk. Finally, they verify the main service wires entering the panel are sized adequately for the property’s electrical needs, checking the amperage rating to ensure it can safely handle the home’s current and future electrical load.

Assessing the Wiring and Connections

The bulk of the electrical system is hidden inside the walls, but an electrician carefully inspects all accessible wiring in the basement, attic, crawlspace, and visible utility areas. This inspection focuses on the integrity of the wires and the safety of their connections. The professional looks for visible signs of damage, such as brittle or cracked insulation that could expose live wires, or signs of rodent damage in attics that may compromise the circuit.

The type of wiring is also assessed. If the home has aluminum branch circuit wiring, common in homes built between the mid 1960s and early 1970s, the inspector will verify that proper, specialized connections were used where the aluminum wire meets copper terminals. Without these proper connections, aluminum wiring can loosen and overheat, creating a significant fire hazard.

Accessible junction boxes are critical safety points that must be checked. A junction box is where electrical wires connect to split a circuit. The inspection ensures every junction box is properly covered with a secure plate. An open junction box is a code violation and poses a serious risk of accidental shock or fire, as sparking wires are exposed to combustible materials in the wall or ceiling. The electrician also checks that the wiring within these boxes is connected with the appropriate wire nuts and is securely tucked away.

Testing Outlets, Switches, and Fixtures

A large portion of the inspection involves testing the home’s interface devices: the receptacles (outlets) and switches. The electrician uses specialized equipment to test every representative outlet in the home for proper function. This includes checking for correct voltage, verifying the outlet is properly grounded, and ensuring correct polarity. Reversed polarity means the hot and neutral wires are swapped, which is a hidden shock hazard that can energize an appliance chassis, leading to a fatal shock.

Crucially, the inspection focuses on the safety devices required by modern electrical code: the Ground Fault Circuit Interrupters (GFCIs) and Arc Fault Circuit Interrupters (AFCIs). GFCIs are required in wet areas like bathrooms, kitchens, garages, and basements. The inspector manually tests these receptacles to ensure they trip immediately when a simulated fault occurs, verifying they will protect against severe electric shock. AFCIs are required in most living areas and are designed to prevent fires by detecting the unique electrical signature of a dangerous arc fault in the wiring. The electrician tests these devices to confirm they are functional and installed where required.

Furthermore, the condition of the switches and receptacles is assessed. Loose outlets that wiggle when a plug is inserted are noted. This looseness can cause arcing and eventual heat buildup. Light switches are checked for proper function and examined for signs of overheating, such as discoloration or a clicking sound, which can indicate a failing switch component.

Identifying Code Compliance Issues and Hazards

An electrical inspection is primarily a measure of compliance against current safety standards. Even if a home was built to code fifty years ago, that code has evolved dramatically. The inspector identifies elements that are no longer considered safe or compliant.

One of the most immediate hazards is the presence of outdated wiring, such as “knob and tube” wiring, which lacks a ground wire and has insulation that can become extremely brittle and hazardous. The inspector also checks for improper modifications or do it yourself mistakes, such as using improper wire gauge for a circuit, relying on fragile “backstab” connections instead of secured screw terminals, or running extension cords through walls as permanent wiring. These amateur errors are frequent causes of electrical fires.

The inspection addresses safety clearances around the electrical panel. Code mandates a specific amount of clear space must be maintained in front of and around the panel to allow an electrician to safely access and service the box. Storing clutter, furniture, or flammable materials near the panel is a violation and a dangerous practice. The professional will also verify that smoke alarms and carbon monoxide detectors are present, functional, and correctly located according to the latest safety standards, ensuring the occupants are warned of a potential fire or gas leak.

Who Needs an Electrical Inspection and Why

The need for a professional electrical inspection extends beyond the real estate transaction. Every responsible Idaho Falls homeowner should consider one for specific situations.

Any home built prior to 1980, before many of today’s modern safety codes were implemented, should have an inspection. Older panels, aluminum wiring, and lack of GFCI/AFCI protection pose inherent risks that only an inspection can reveal. Before undertaking any major remodel, such as a kitchen overhaul or a room addition, an inspection is mandatory. This ensures the existing electrical service has enough capacity to handle the new load safely, preventing the dangerous overload of an existing panel.

Installing any major new electrical load, such as an electric vehicle charger, a new central air conditioner, or a hot tub, requires an electrical assessment to verify the panel and circuits can handle the increased demand. Finally, if you are experiencing persistent electrical issues that you cannot explain, such as constantly tripping breakers, buzzing from the walls, or unexplained power outages, an inspection is required to diagnose the root cause of the problem.
