When Should You Perform an Electrical Inspection?

While some people may choose to perform DIY inspections, it is always recommended to hire a licensed electrician to conduct thorough inspections. However, as a homeowner or business owner, you should still know when to schedule a professional inspection. Here are some key instances when an electrical inspection is needed:

1. Before Purchasing a Property

If you are considering buying a new home or commercial building, it is important to have the electrical system inspected before finalizing the purchase. This will help identify any hidden electrical issues that could become expensive to repair later. A pre-purchase inspection gives you peace of mind knowing that the electrical system is safe and up to code.

2. When You Notice Flickering Lights or Frequent Breaker Trips

Flickering lights, frequent circuit breaker trips, or light bulbs burning out too quickly are signs of electrical issues. These problems could be a sign of overloading circuits, faulty wiring, or problems with the electrical panel. An inspection can help diagnose and resolve these issues before they worsen.

3. After Renovating or Adding Electrical Components

Any time you renovate your home or business, adding new electrical components, outlets, or appliances, it’s important to inspect the entire system. Renovations can often result in improperly installed wiring or overloaded circuits. A post-renovation inspection will ensure that your electrical system is functioning correctly and that new components are properly integrated into the existing system.

4. If Your Home Is Over 25 Years Old

Older homes, especially those built before the 1970s, may have outdated wiring and electrical systems. Inspections are particularly important for older homes, as they may have wiring that no longer meets modern standards. If you live in an older house, schedule an electrical inspection every few years to check for wear and tear or other hazards.

5. When You Experience Power Surges or Equipment Malfunctions

Power surges or malfunctioning equipment can indicate an underlying electrical problem. Frequent electrical surges or faulty appliances could be the result of problems in the wiring, circuit board, or grounding system. A professional inspection can help pinpoint the cause of these surges and prevent further damage.

How to Perform a Regular Electrical Inspection

Performing a regular electrical inspection involves evaluating various components of the electrical system in your home or business. While certain aspects of an electrical inspection should only be performed by a licensed electrician, there are steps you can take to monitor the health of your system.

1. Examine the Electrical Panel

The electrical panel (also called the breaker box) is the heart of your electrical system. It distributes electrical power to various circuits throughout the building. Checking your electrical panel should be one of the first steps in any inspection.

Look for Overloaded Circuits: Each breaker should correspond to a specific circuit, and no breaker should be overloaded. If a breaker trips frequently, it may indicate that the circuit is overloaded or there is a fault in the wiring.
Inspect for Rust or Moisture: Rust or moisture in the panel can be a serious concern. Moisture could indicate water intrusion, which could lead to electrical shorts or fires. If you notice rust or water, consult a professional electrician immediately.
Check for Labeling and Properly Sized Breakers: Ensure that the breakers are properly labeled, and verify that each breaker is the correct size for the circuit it protects. Incorrectly sized breakers can be a fire hazard.

2. Inspect Wiring for Damage or Wear

Worn or damaged wiring is one of the most common causes of electrical hazards. Over time, insulation can deteriorate, and wires can become frayed or exposed. Look for signs of wear, such as:

Exposed Wires: Wires should be properly insulated. If any exposed wires are visible, they should be repaired or replaced immediately.
Frayed or Damaged Wiring: Inspect visible wiring for fraying, nicks, or cuts. If you find any damaged wires, they need to be replaced to prevent short circuits or electrical fires.
Burn Marks: Discoloration or burn marks on the wiring or outlets are a sign of overheating. This could be caused by faulty wiring, an overloaded circuit, or a malfunctioning appliance. If you see burn marks, turn off the power and contact an electrician to assess the situation.

3. Check Outlets and Switches

Outlets and switches should be checked to ensure they are in good working order. Here’s what to look for:

Loose or Flickering Outlets: If you notice outlets or switches that are loose, flickering, or sparking when used, this is a sign of a problem that should be addressed immediately.
Test GFCIs (Ground Fault Circuit Interrupters): GFCIs are designed to protect against electrical shock in damp or wet areas like bathrooms, kitchens, and outdoor spaces. Test each GFCI outlet to ensure it trips when the test button is pressed. If it doesn’t, the outlet may need to be replaced.
Check for Overcrowding: Too many plugs or extension cords plugged into one outlet can cause an overload. Overloading can lead to overheating and potential fires, so be sure to distribute electrical loads properly.

4. Evaluate Appliances and Electrical Equipment

Inspecting the condition of your appliances and electrical equipment can help you identify potential hazards:

Look for Overheating: Appliances that overheat could indicate a malfunction or excessive power draw. If you notice an appliance overheating, unplug it and consult a professional.
