ERMS options can be included with many new circuit breakers and can be retrofitted to existing installed circuit breakers.

• A. True
• B. False
• C. Not specified
• D. Cannot be determined

Answer: (A)

ERMS options are designed as modular enhancements that can attach to circuit breakers to add monitoring and reporting capabilities. Because they’re built as add‑on modules or retrofit kits, they’re commonly offered in two ways: included with new breakers at the time of manufacture, and available as a retrofit for existing installed breakers. This flexibility lets you upgrade protection, diagnostics, and safety features without replacing the entire breaker, which is why the statement is true. Always verify compatibility for a specific breaker model, but the general practice is to provide ERMS as both a factory option and a field retrofit.
