Electrical System Warning Signs That Insurance Inspectors Take Seriously

In 2023, over $1.2 billion in insurance claims were caused by power shortages due to lightning. When an electrical system is overloaded or a surge lacks proper protection, it can and will cause severe damage to appliances, inventory, and infrastructure, and pose a risk to people in the building.

To help reduce these issues, insurance companies often require forensic investigations after an event or preventative electrical system evaluations. These professionals walk around your commercial, industrial, or residential space under the mindset that everything will fail. They’re not there to assume a disaster, but to identify any preventable risks before they become an extreme expense.

At Dreiym Engineering, we help identify these same issues while also providing guidance and actionable steps for managing arc-flash risk, proper grounding, and other common problems. Here are some of the electrical dangers your insurance inspector will consider.

Why Insurance Inspectors Focus on Electrical Risk First

Not every insurance provider will issue an inspection. However, when they do require such processes, it almost always begins with an electrical risk assessment. The reason for this prioritization is simple: electrical failures are often catastrophic. They occur in unpredictable circumstances, and once they start, they frequently escalate quickly, making it difficult to determine the cause.

Unlike minor plumbing problems or occasional cosmetic damage to a building, electrical issues tend to result in complete shutdowns. You might experience a surge that knocks out power to your garage, or a business could face injury claims and significant property damage.

The more interconnected your electrical system, the higher the risk of one electrical fault spreading throughout the rest of your building. That is even more the case with automated systems, refrigeration, medical equipment, or data operations. A good insurance inspector wants to know if your facility or residential space has control over such an electrical environment.

The Most Common Electrical Warning Signs That Trigger Concern

Insurance inspectors want the reassurance that you fully understand the risk profile of your business or residential space. They will discuss the risks you currently face, what needs maintenance, what should be upgraded, and whether you need to document any preventive measures for the future.

In many cases, when we get hired at Dreiym, companies are looking for a proactive electrical safety inspection before an insurance inspector shows up. While many red flags could end up in a report, some of the more common warning signs insurance inspectors point out include:

• Repeated or recurring breaker trips, especially in the same zones or when they are unexplained
• Frequent flickering lights across all areas of a space, including production, warehouse, or offices
• If any panels are buzzing or too warm, and they smell odors from overheated insulation
• Visible corrosion or moisture intrusion near anything that is part of the electrical infrastructure
• When legacy panels operate well beyond the original load capacity
• Equipment behaving inconsistently, especially after a power surge or disturbance
• Anything that may be at risk during extreme weather or full load stress
• Outdated wiring (like knob-and-tube), fuse boxes, lack of GFCIs, and overloaded breakers

All these systems represent clear issues with electrical system stability. It means the load behavior of your building or the protection coordination of your residential space is at risk and poses a financial problem for the insurance provider.

Grounding Issues Inspectors Flag Immediately

Grounding is something we should discuss for a little while. This red flag crops up a lot with insurance inspectors because it is easy to verify and significantly increases the risk of damage down the road.

Proper ground testing will tell you if there is direct liability exposure. Grounding affects fault clearing, shock protection, and system stability. Whenever these systems degrade, the fault current may not return to its source through a safe route. That leads to protective processes not working when needed or to voltage hazards that workers, pets, or kids can touch by accident.

The greater the risk your electrical system poses, the more it costs to insure. By getting an electrical system evaluation ahead of any insurance inspection, you reduce your monthly expense because the provider doesn’t see as much risk. After all, insurance is a number game, and the provider wants to win.

Commercial spaces receive much more scrutiny from an insurance inspector than residential spaces do. They are not interested in whether the system “works.” They want to know what will happen if it operates under full or increased stress. That can be anything from a lightning strike to a storm outage to a neighboring building siphoning off electricity through a bunch of extension cords.

In these commercial spaces, inspectors look for overloaded conductors, poor load distribution, improper modifications during and after renovations, electrical room conditions, and fire risk. Even the dust building up on electrical panels is being considered by an experienced, detail-oriented inspector.

Equipment and Documentation Failures That Create Insurance Exposure

One other point to mention about commercial spaces and insurance inspectors is documentation. Compliance issues are serious and should never be taken lightly. Between 2011 and 2021, there were 1,201 workplace fatalities involving electrical issues reported by OSHA. Insurance inspectors know this and do everything possible to avoid their company having to pay for a death, injury, or loss of assets.

To ensure the people and places being insured comply with regulatory codes, documentation is required. When an insurance inspector arrives at a commercial space, they will often request all previous records, drawings, and diagrams.

Any missing documentation will quickly signal you have unmanaged exposure or hidden risk that complicates post-incident accountability. Without records on maintenance, testing, and follow-up, you increase the chances of a much higher monthly insurance bill. Documentation is risk management, and doing your due diligence reduces uncertainty in claims.

Practical Steps Facilities Can Take Before an Insurance Inspection

If you’re worried about your home, commercial, or industrial space getting “hit” during an insurance inspection, there are some proactive things you can do to reduce issues later. That might include:

• Do an electrical walkthrough of your entire system before any inspection
• Confirm all wires are properly insulated, secured, and grounded
• Review any load changes before, during, and after renovations, expansions, or upgrades
• Make sure there is plenty of clearance around any electrical panels or zones
• Update all your documentation and compliance packages
• Demonstrate that you have investigated any red flags and have taken steps to address them

Inspectors aren’t looking to “catch” you in a lie. They are simply addressing risk. If you can show that you recognize the risk and are willing to take steps to reduce it, they will be happy to work with you. It comes down to lowering financial responsibility and making their job easier.

Address Electrical Risk Before Inspectors Arrive

Insurance inspectors will focus on your electrical systems. They want to reduce the risk of fire, operational shutdowns, and property and personal injury. During an inspection, these professionals will unearth any costly or dangerous risks and put them into a report that directly impacts your monthly premiums and regulatory compliance.

Take the time to do as many of these inspections ahead of time. You can cover a lot of ground by stress testing your electrical system and visually inspecting all associated devices, wires, panels, and protection equipment.

A good first step is to hire an experienced team like ours for electrical system evaluations and ground testing. For more than 30 years, we have worked with residential, commercial, and industrial clients, helping to ensure a safe and operable electrical system long before an incident occurs. We can help identify the problems you need to address so that when the insurance inspector arrives, there are few to no red flags.
