Class I vs. Div 2 Panelboard: Which One Should You Choose?

Understanding Class I and Division 2 Panelboards

Choosing the right panelboard for your needs is crucial. Class I and Division 2 panelboards serve different purposes. Let's explore their features to determine which is best for you.

The Basics of Class I Panelboards

Class I panelboards are designed for environments where flammable gases or vapors may be present. This includes industries like:

1. Oil and gas
2. Chemical processing
3. Paint spraying

As Sarah, an electrical engineer, puts it: “Class I is all about safety. You want to avoid ignition sources around those risky chemicals.”

What About Division 2 Panelboards?

Division 2 panelboards are used in areas where flammable materials are present but not typically in a hazardous condition. This means:

1. Hazardous substances are not likely to escape.
2. Areas might only see occasional exposure.

Mike, a safety officer, notes, “Division 2 locations can still be risky, but we take precautions knowing the hazards are less frequent.”

Key Differences Between Class I and Division 2

Now let’s break down the differences:

• Safety Environment: Class I is high-risk; Division 2 is lower-risk.
• Installation Requirement: Class I panels need more protective measures.
• Cost: Class I panels are generally more expensive due to their robust safety features.
• Application: Choose Class I for constant hazards; opt for Division 2 for occasional risks.

Before making a choice, consider these factors.

Which One Should You Choose?

Your choice depends on your specific needs. If you work in a high-risk area, Class I is your best bet. If your environment is safer with occasional hazards, Division 2 is suitable.
