If a sign's rating is 1500 VA, which value should be used for the sign branch circuit load?

If a sign's rating is 1500 VA, which value should be used for the sign branch circuit load?

• A. 1200 VA
• B. 900 VA
• C. 1500 VA
• D. 1800 VA

Answer: (C)

Sign branch-circuit load is taken from the sign’s nameplate rating in VA. That rating represents the total electrical demand the sign will draw during normal operation, including all drivers, ballasts, and transformers. So when a sign is rated at 1500 VA, the branch circuit should be sized for 1500 VA, not a reduced or increased value. The other numbers would imply applying arbitrary percentages or multipliers that aren’t part of how this load is defined for signage. If more than one sign shared the same circuit, you’d sum their VA ratings, but for a single sign, use its 1500 VA rating.
