ANSI E1.58-2017
Electrical Safety Standard for Portable Stage and Studio Equipment Used Outdoors
E1.58 addresses the planning and execution of temporary outdoor portable electrical installations in compliance with the intent of NFPA 70, National Electrical Code, Sections 520.10 and 530.6 which state that ôPortable stage and studio lighting equipment and portable power distribution equipment not identified for outdoor use shall be permitted for temporary use outdoors, provided the equipment is supervised by qualified personnel while energized and barriered from the general public.ö (This quote is from 520.10; 530.6 is similar.) Safety is the primary concern. Conditions that degrade the operational performance or life of the electrical equipment are secondary.
