Prep boundary
Direct answer
Why can a double-tapped breaker be a concern when it is not listed for two conductors is a TradeCert Prep study concept connected to NHIE Practice Test prep, not a copied official exam item. A terminal not designed for two conductors may loosen or overheat and should be reported. Always verify licensing, certification, and testing rules with the current official candidate bulletin, state manual, code book, or testing provider before relying on a detail for compliance.
