What is a safety requirement for stage lighting equipment?

• A. Stage lighting equipment must be grounded or double insulated.
• B. Stage lighting equipment may be ungrounded if portable.
• C. Stage lighting equipment does not require safety certification.
• D. Stage lighting equipment should be painted bright red.

Answer: (A)

Electrical safety for stage lighting hinges on protecting people from touching live parts. The best rule is that lighting equipment must be grounded or double insulated. Grounding provides a path for fault current to go to earth, which makes protective devices trip and keeps exposed metal parts at a safe potential, reducing shock risk. Double insulation, used in Class II equipment, adds extra layers of insulation so the outer surface can’t be energised even if an internal part fails. Portable gear can be designed either to be grounded or to be double insulated, but either approach achieves the necessary protection. Statements that gear can be ungrounded, that safety certification isn’t needed, or that color changes safety neglect the actual protections in place and don’t meet established safety standards.
