Understanding Workers’ Comp Class Code 5190 (Electrical Wiring)

Workers’ compensation insurance is essential for businesses in the construction and electrical trades. One specific classification that applies to electrical work inside structures is workers’ comp class code 5190. Insurance carriers use this classification to determine premiums for businesses whose employees perform electrical wiring tasks within buildings, and getting it right affects both what you pay and whether claims get paid.

If your business involves electrical work and you want to make sure you’re properly classified while keeping insurance costs manageable, understanding class code 5190 matters. Contact NPN Brokers at (561) 990-3022 for a quick quote and coverage that fits how your crews actually work.

What Is Workers’ Comp Class Code 5190?

Workers’ comp class code 5190 applies to employees engaged in electrical wiring within buildings. The code is specifically for interior electrical work, meaning it covers tasks performed inside residential, commercial, or industrial structures. It does not apply to outdoor electrical work, such as power line installation or street lighting, which falls under different class codes.

Insurance companies use class codes like 5190 to assess risk levels and calculate premiums. Interior electrical work often involves live wires, confined spaces, and elevated locations, so it carries moderate risk compared to some other trades. Knowing exactly how your business fits within this classification helps ensure you’re paying the right premiums and maintaining proper coverage.

Who Does Class Code 5190 Apply To?

This class code primarily applies to businesses and employees involved in electrical work within structures. Electrical contractors specializing in interior wiring fall under class code 5190. These contractors handle projects such as installing wiring for new construction, renovations, or repairs within existing buildings. Journeymen and master electricians performing wiring tasks inside buildings are categorized under this code as well. Their work includes installing outlets, switches, light fixtures, circuit breakers, and electrical panels.

Maintenance workers who perform routine electrical repairs and upgrades within commercial or residential properties also fall under class code 5190, provided they work exclusively indoors. Even apprentices assisting licensed electricians on interior wiring projects are covered under this classification. Business owners should know which employees belong under this code to ensure accurate reporting and avoid unnecessary costs.

Types of Work Covered Under Class Code 5190

The scope of work under class code 5190 includes a wide range of electrical tasks performed within buildings. These tasks typically involve installing electrical systems in new construction, rewiring existing structures during renovations, and installing and maintaining light fixtures, outlets, and switches. Electricians under this classification also upgrade electrical panels and circuit breakers, install low-voltage systems such as security alarms and data cables, and troubleshoot and repair interior electrical issues.

Outdoor electrical work, such as installing transformers or working on overhead power lines, falls under different class codes. Misclassifying work can lead to claim denials and increased premiums, so employees need to be categorized based on the work they actually perform, not a job title.

Workers’ Comp Insurance Requirements for Class Code 5190

Businesses with employees performing interior electrical work must carry workers’ comp insurance to comply with state laws and protect their workforce. Requirements vary by state, but most states mandate coverage if you have at least one employee. This insurance provides coverage for medical expenses if an employee is injured while performing electrical work inside a building. It also covers lost wages if an injury prevents an employee from working and provides employer liability protection against lawsuits related to workplace injuries.

The right workers’ comp policy protects your employees and shields your business from financial strain. Without proper coverage, your business could face fines, lawsuits, and increased premiums. Correctly classifying your employees under class code 5190 helps you meet these requirements while keeping costs manageable.

Risk Factors for Class Code 5190

While interior electrical work is less hazardous than outdoor power line work, it still carries real risks, and insurance companies weigh these factors when calculating premiums. Working with live wires creates the risk of electrical shocks, which can cause severe injuries. Electricians often work on ladders or scaffolding, increasing fall exposure. Work in crawl spaces, attics, or tight mechanical rooms poses additional challenges, and faulty wiring or improper installations can lead to electrical fires.

Strict safety protocols and thorough employee training help businesses mitigate these risks and can lower insurance premiums over time. Regular safety inspections, proper use of personal protective equipment (PPE), and a genuine culture of safety all reduce workplace injuries and make your account more attractive to underwriters.

Exclusions and Related Class Codes

While class code 5190 covers most interior electrical work, certain tasks fall under different classifications. Outdoor electrical work involving power lines and transformers falls under class code 7539. Installing security systems and fire alarms is classified under class code 7600, while running data and phone lines typically falls under class code 7605.

Electrical wiring is also frequently confused with other construction trade classifications. If your crews perform work beyond wiring, review the other codes that may apply; our guide to workers’ comp class code 5701 explains another common construction classification and when it applies instead. Proper classification is essential for avoiding overpayment or gaps in coverage, and a knowledgeable broker can confirm each employee sits under the right code.

Why Proper Classification Matters

Misclassifying employees can lead to higher premiums, penalties, or uncovered claims. Classifying outdoor electrical workers under code 5190, for instance, could result in claim denials if an injury occurs outside a building. Proper classification ensures your business only pays for the coverage it needs while staying compliant with state regulations.

An experienced insurance broker keeps your business properly classified and helps you find cost-saving opportunities within a complex classification system. That includes separating payroll correctly between codes when employees perform mixed duties, which is one of the most common places contractors overpay.

What Affects Workers’ Comp Costs Under Class Code 5190?

Premiums for code 5190 are calculated the same way as other classifications: the state-filed rate for the code is applied per $100 of payroll, then adjusted by your experience modification factor and any carrier credits or debits. Several factors move that number up or down.

Your claims history carries the most weight. A clean loss run over several years earns a lower experience mod, while frequent claims, even small ones, push premiums higher. Payroll accuracy matters too. If clerical staff or estimators are lumped into 5190 payroll instead of a lower-rated office code, you pay electrician rates on office salaries. State rates also vary considerably, so a contractor operating in more than one state should expect different costs for identical work. Finally, how you pay matters: pay-as-you-go plans base premiums on actual payroll each period, which suits contractors whose crew size changes from project to project.

Class Code 5190 for Staffing Agencies and Temporary Electricians

Staffing firms that place electricians, electrical helpers, and low-voltage techs on client job sites face an extra layer of complexity. The classification follows the work being performed at the client’s site, so a staffing agency may carry code 5190 alongside several other trade codes on a single policy. Carriers scrutinize these accounts closely, and many decline them outright. We work with staffing firms in the trades every day; our page on workers’ comp insurance for construction labor staffing agencies covers how we place this kind of risk.

If your agency supplies workers across several trades or industries, correct code assignment per placement is what keeps audits clean. Our guide to workers’ comp class codes for staffing agencies walks through how multi-code policies are structured and where agencies most often get tripped up.

Frequently Asked Questions About Workers’ Comp Class Code 5190

Is class code 5190 only for licensed electricians?

No, it applies to anyone performing interior electrical work, including apprentices and maintenance electricians. As long as the work is performed inside a structure, the employee falls under class code 5190.

Can I use class code 5190 for outdoor electrical work?

No, outdoor electrical work falls under different class codes, such as 7539 for power line construction. Using the correct classification is crucial to ensure claims are covered and premiums remain accurate.

How can I lower my workers’ comp premiums?

Implementing safety programs, maintaining a low claims history, and working with a knowledgeable broker can help reduce your premiums. Regular safety training and thorough risk assessments further lower your exposure.

What happens if I misclassify my employees?

Misclassification can lead to higher premiums, denied claims, and potential penalties during audits. Accurate classification ensures proper coverage and prevents unexpected costs.

Does class code 5190 cover low-voltage work like alarms and data cabling?

Usually not. Security systems and fire alarm installation typically fall under code 7600, and data or phone lines under 7605. If your employees split their time between building wiring and low-voltage work, payroll may need to be separated between codes, so review the split with your broker.

Can a staffing agency placing electricians use code 5190?

Yes. When a staffing agency places workers who perform interior electrical wiring at client sites, those placements are generally classified under 5190. The agency’s policy must reflect the actual duties at each assignment, which often means carrying multiple class codes at once.
