Which organization listing is represented by UL/CSA (ULc) for electrical equipment?

• A. UL/CSA (ULc)
• B. NFPA
• C. IEC
• D. CSA

Answer: (A)

Listing marks show which organization has verified a product’s safety for use. The UL/CSA (ULc) designation is a joint certification indicating that Underwriters Laboratories and the Canadian Standards Association have tested and listed the equipment for Canada. The ULc mark specifically targets the Canadian market, showing the product meets safety requirements recognized by UL in partnership with CSA. This is why it’s the best answer: it directly identifies the joint UL/CSA listing for electrical equipment intended for Canada. NFPA and IEC are standard-setting bodies, not the specific product listing mark in this case, and CSA alone denotes CSA certification without the UL collaboration.
