Quick Tool: G99 Type Checker

Enter rating and connection voltage to estimate Type A–D classification (simplified). Confirm with your DNO and EREC G99.

Why it matters

Classification affects compliance responsibilities, documentation, and verification testing. Use this as a quick sense-check during early siting and feasibility.
