Let me walk you through what happens when a fire marshal traces a house fire back to a junction box your crew wired 18 months ago.
The property owner calls their insurance company. Their insurance company pays the claim. Then their insurance company's subrogation attorney starts looking for someone to sue. The fire investigator's report says the fire originated at an electrical connection point in the attic. Your company's name is on the permit.
Now you have a lawsuit. The job was finished over a year ago. Your crew has moved on to dozens of other projects. But your liability did not leave when your van pulled out of the driveway.
This is the exposure that most electrical contractors either do not understand or do not think about until it shows up as a certified letter from a law firm. Here is how it works, what it costs when it goes wrong, and how the right insurance setup keeps it from ending your business.
According to the National Fire Protection Association (NFPA), U.S. fire departments responded to an average of 46,700 home fires involving electrical failure or malfunction per year from 2015 to 2019. Those fires caused an average of 390 deaths, 1,330 injuries, and $1.5 billion in direct property damage annually.
The U.S. Fire Administration (USFA) tracks similar data and reports 23,700 residential electrical malfunction fires in 2023 alone, causing 305 deaths, 800 injuries, and over $1.5 billion in property damage.
Electrical distribution, lighting, and power transfer equipment accounted for nearly half of all home fires involving electrical failure. That means wiring, panels, outlets, and connections - the work electrical contractors do every day.
Not every one of those fires traces back to a contractor's work. But when the fire investigation points to a wiring installation, a loose connection, or an improper splice, the contractor who did the work is the first name on the lawsuit.
Fire investigation is not guesswork. Investigators follow NFPA 921, the Guide for Fire and Explosion Investigations, using the scientific method to determine origin and cause.
Here is what they look at:
According to forensic engineering firm Rimkus, investigators can distinguish between arc damage that caused the fire and arc damage that resulted from the fire. A series arc fault in a loose connection can produce enough heat to ignite surrounding materials even at current levels below what a standard circuit breaker would trip on. That means the breaker did not fail. The connection your crew made did.
The fire marshal writes the report. The insurance company's forensic engineer confirms it. Your company name is on the permit. The timeline between your work and the fire is documented. That is the chain that connects you to a seven-figure claim.
Your commercial general liability (CGL) policy has two main zones of coverage for your work.
Ongoing operations covers claims for bodily injury or property damage that happen while your crew is on the job site, actively doing the work. A helper drops a panel on a homeowner's foot. A wire run damages existing drywall. That is ongoing operations.
Completed operations covers claims that arise after the work is finished and turned over to the property owner. The ISO CGL Coverage Form (CG 00 01) defines the products-completed operations hazard as bodily injury or property damage occurring away from premises you own or rent and arising out of your work, after that work has been completed.
For electricians, completed operations is where the real exposure lives. Here is why: the damage from faulty electrical work almost never shows up the day you finish the job. It shows up months or years later when a connection fails, an overloaded circuit finally degrades, or a splice in an attic junction box arcs and ignites insulation.
A few things to understand about how the coverage works:
These are the types of claims that come through on electrical contractor policies. They are not hypothetical.
The commercial building fire. An electrical contractor rewires a manufacturing plant. Two years later, an electrical fire destroys the building and all the equipment inside. The building owner sues for replacement cost of the structure, the machinery, and lost revenue during reconstruction. According to claims data compiled by ENCON Group, the settlement in one such case was $3.5 million.
The residential callback. A homeowner hires an electrician to upgrade a panel and add circuits for a kitchen remodel. Eight months later, a connection in the new panel overheats and starts a fire in the wall cavity. The fire does $280,000 in damage to the home before the fire department arrives. The homeowner's insurer pays the claim and subrogate against the electrician.
The arc flash on a service call. Two employees working for an electrical contractor were replacing wiring at a commercial building when one contacted 480 volts in a disconnect panel, causing an arc flash that hospitalized both workers with severe burns to their entire bodies. This was an OSHA-investigated incident from 2020. While this is a workers' compensation and ongoing operations scenario, it shows the severity of electrical injury claims.
The delayed discovery. Faulty wiring in a junction box sits behind drywall for three years before a connection fails and shorts. The short trips nothing because it is a series arc fault below the breaker threshold. The resulting fire guts an upstairs bedroom and causes smoke damage throughout the home. The electrician who did the original rough-in is named in the suit. Their work was inspected and passed. It does not matter. The claim still comes.

If a fire or injury traces back to work that violated the National Electrical Code (NEC), your legal position gets significantly harder to defend.
When states adopt the NEC into their building codes - and most do - a violation of the NEC becomes a violation of state law. Courts in multiple states have ruled that violating an adopted building code constitutes negligence per se. That means the plaintiff does not have to prove you were careless. The code violation itself establishes the breach of duty. They only need to prove the violation caused their damages.
In a Virginia case (Savoy Construction Co.), the court found that a contractor's failure to plug and seal cable conduit after installation violated the NEC as incorporated in the Virginia building code and constituted negligence per se.
For electricians, this means:
Some CGL policies for electrical contractors have gaps that do not become obvious until you file a claim.
Completed operations excluded or capped. Some carriers write completed operations at lower aggregate limits than your per-occurrence limit, or exclude it entirely for certain work types. High-voltage work, solar installations, EV charging systems, and generator work are common exclusion targets. If your completed operations aggregate is $1 million and you face a $3.5 million fire claim, you are personally on the hook for $2.5 million.
Policy lapsed between jobs. Completed operations coverage only responds if the damage occurs during an active policy period. If you cancel your GL policy in January and a fire from your October wiring job happens in March, there is no coverage. This is why maintaining continuous coverage matters, even during slow seasons.
No additional insured endorsement for the GC. General contractors on commercial projects require additional insured status on your policy, including for completed operations (typically via ISO endorsement CG 20 37). If you do not have this endorsement, you breach your subcontract, and the GC's claims against you have no coverage path through your policy.
This is the practical part. Here is what an electrician's insurance setup should look like to handle completed operations exposure.
Your liability does not end when you pull your tools out of the van and drive away. It follows you for years. A fire that starts from a connection you made 18 months ago is your claim. A property owner who discovers code violations in your work three years later has standing to sue. An arc fault in a junction box that sat quietly for two years before igniting - that traces back to you.
Completed operations coverage exists specifically for this exposure. It is not optional for electrical contractors. It is the coverage that stands between you and a claim that could end your business.
If you are not sure what your current policy covers, or if you are carrying exclusions you did not know about, get it reviewed. If you need contractor insurance that actually covers the work you do, talk to someone who understands electrical contractor risk.
It depends on your state's statute of repose for construction defects. Most states set this between 6 and 10 years after substantial completion of the work. Some states extend it to 12 or even 15 years. During that entire window, a property owner or injured party can file a claim against the electrician whose work caused the damage.
Yes, but only if your policy includes completed operations coverage. Standard CGL policies bundle this in, but some carriers exclude it or write it at reduced limits. If a fire starts six months or two years after you finished the job and is traced back to your wiring, completed operations is the coverage that responds. Without it, you are paying for the defense and the damages out of pocket.
Ongoing operations covers claims for injuries or property damage that happen while your crew is still on the job site doing the work. Completed operations covers claims that arise after the work is finished and turned over to the property owner. For electricians, both exposures are real. But completed operations is where the big-dollar claims live, because fires and equipment failures from wiring defects can show up months or years later.
Generally, a lawsuit requires actual injury or property damage. But a code violation discovered during an inspection can lead to mandatory rework at your expense, fines, license discipline, and disqualification from future projects. If that code violation later contributes to a fire or injury, it becomes powerful evidence of negligence. Courts in multiple states have treated NEC violations adopted into local building codes as negligence per se, meaning the violation itself establishes the breach of duty.
Completed operations coverage is typically bundled into your CGL policy, not sold separately. For electrical contractors, CGL premiums vary based on your revenue, payroll, claims history, and the type of electrical work you perform. High-voltage and industrial work carries higher premiums than residential service calls. The cost of the coverage is a fraction of what a single fire claim would cost without it. A $3.5 million claim settlement is not unusual for an electrical fire in a commercial building.
