About Class Code 5193

NCCI class code 5193 covers COMPUTER OR TELEPHONE SYSTEM INSTALL within the Plumbing, Heating, and Air-Conditioning Contractors industry. This classification is used by insurance carriers to determine workers’ compensation premium rates based on the risk level associated with these job duties.

Primary vs Secondary Classification

This is a Primary Classification

Class code 5193 is a primary classification, meaning it directly describes the main business operations of an employer. Primary codes represent the core activity — what the business actually does.

A secondary (or standard exception) code describes support operations that exist in almost every business, like clerical work (8810) or outside sales (8742). These are assigned in addition to the primary code.

If your business primarily involves computer or telephone system install, this code should be your governing classification — the one that applies to most of your payroll.

How Class Code 5193 Affects Your Premium

Your workers’ compensation premium for employees classified under code 5193 is calculated as:

Premium = (Payroll / 100) × Rate × EMR

Where the rate is determined by your state and carrier, and EMR (Experience Modification Rate) reflects your company’s claims history relative to similar businesses. A lower EMR means lower premiums.

Accurate classification is critical — misclassifying employees under the wrong code can result in overpayment or underpayment that gets corrected during an audit.

Classification Guidance

Class code 5193 (COMPUTER OR TELEPHONE SYSTEM INSTALL) is the right fit if your employees’ primary duties involve work described by this classification within the Plumbing, Heating, and Air-Conditioning Contractors industry.

Consider these factors when selecting your class code:

Actual duties matter, not job titles. An employee titled "Manager" but performing physical labor should be classified under the physical work code.
One employee can only have one code. If duties span multiple classifications, assign the code that represents the majority of their work time.
Check state-specific codes. This code uses the standard NCCI number in all states.
Audit readiness. Keep documentation of job descriptions and duties to support your classification during a workers’ comp audit.
