Which statement describes Listed in equipment approvals?

• A. Listed: equipment or materials included in a list published by an organization acceptable to the AHJ
• B. Listed: a label, symbol or identifying mark attached to equipment by an organization acceptable to the AHJ
• C. Listed: a warranty certificate issued by the manufacturer
• D. Listed: a color coding scheme verified by the AHJ

Answer: (B)

Listed means the equipment has been evaluated by a recognized testing laboratory and carries a label, symbol, or identifying mark that proves it meets the required safety standards. That mark is attached to the equipment by the testing organization, and the AHJ uses it to confirm listing during inspections. Being on a separate list, having a warranty certificate, or using a color-coding scheme does not by itself establish listing, whereas the presence of the label or mark from an approved organization is the evidence inspectors look for.
