The standard of care for electrical system safety in dramatic art facilities in the education, and other industries, is largely established in Articles 518 through Article 540 of the National Electrical Code (NEC). In some instances, dramatic art activity takes place in athletic arenas so we are mindful of parent standards for assembly occupancies generally; found in Chapter 3 of the International Building Code.

Of particular interest is the “technical power system” found in Article 640: Audio Signal Processing, Amplification, and Reproduction Equipment.

Note the imperfect correlation between the NFPA and ICC occupancy definitions. This never happens by design but is sometimes necessary. Some risk aggregations have to be understood as terms of art; to be understood by seasoned experts in context. Also, keep in mind that the NEC is a wiring installation safety code.
Proposals for revisions to assembly-related installations in the for 2023 is linked below:

Second Draft Report for all articles assigned to CMP-15
The so called “song and dance” sections of the NEC have been fairly “stable” in recent cycles. Changes to these articles in the NEC 2020 revision are incremental — i.e clarifications on grounding, wiring methods, cord wiring, illumination — and helpful for designers and inspectors. Nothing budget busting. Convergence of fire safety, mass notification, environmental air and visual experiences continues as once-independent technologies continue integration.
