When building control panels, adhering to the right standards is crucial for safety, efficiency, and global compliance. Two major standards govern panel building: ANSI (American National Standards Institute) and ISO (International Organization for Standardization). But which one should you follow?
In this guide, we’ll break down the differences between ANSI and ISO standards, their applications, and best practices for panel builders.
Key Differences Between ANSI and ISO Standards
| Feature | ANSI Standards | ISO Standards |
|---|---|---|
| Region | Primarily used in the U.S. | Globally recognized |
| Focus | Industry-specific regulations | Broad international consistency |
| Compliance | Required for U.S. market | Needed for international projects |
| Design Guidelines | Detailed electrical safety (e.g., ANSI/NFPA 79) | General quality and safety (e.g., ISO 13849) |
When to Use ANSI Standards
ANSI standards are ideal if:
✔ Your panels are for the U.S. market
✔ You need compliance with NFPA 79 (Electrical Standard for Industrial Machinery)
✔ Your clients require UL certification
When to Use ISO Standards
ISO standards are better if:
✔ Your panels are exported globally
✔ You work with European or multinational clients
✔ Your design must meet IEC (International Electrotechnical Commission) guidelines
Best Practices for Panel Builders
- Know Your Market – Use ANSI for U.S. projects, ISO for international ones.
- Document Compliance – Keep records of certifications for audits.
- Stay Updated – Standards evolve; regularly check for revisions.
Final Thoughts : ANSI vs. ISO Standards
Choosing between ANSI and ISO depends on your project’s location and requirements. While ANSI is dominant in the U.S., ISO ensures global acceptance. By understanding both, panel builders can deliver compliant, high-quality solutions for any market.
