Best wiring safety practice for the illumination of educational settlement occupancies is scattered throughout the National Electrical Code with primary consideration for wiring fire safety:

  • Article 410 – Covers the installation of luminaires (fixtures), lampholders, and lamps, including requirements for wiring, grounding, and support.
  • Article 210 – Covers branch circuit requirements, including those for lighting circuits in dwellings and commercial buildings.
  • Article 220 – Provides guidelines for calculating lighting loads.
  • Article 225 – Addresses outside lighting installations.
  • Article 240 – Covers overcurrent protection for lighting circuits.
  • Article 250 – Deals with grounding and bonding, which is essential for lighting circuits.
  • Article 300 – Covers general wiring methods that apply to lighting circuits.

We have done a fair amount of work on this topic over the years, including writing the chapter on campus outdoor lighting for the soon-to-be-released IEEE 3001.9 Recommended Practice for the Design of Power Systems Supplying Lighting Systems in Commercial and Industrial Facilities.   

For our meeting please refer to the workspace we have set up for the 2026 Revision of the NEC:

2026 National Electrical Code Workspace

We will pick through specifics in the transcripts of Code Making Panels 10 and 18.

“Stopping By Woods on a Snowy Evening”

Randall Thompson’s “Frostiana” is a choral cycle based on the poems of Robert Frost. The cycle consists of settings for mixed chorus and piano, and it was premiered in 1959. “Frostiana” was commissioned to celebrate the bicentennial of the town of Amherst, Massachusetts, and it features seven of Frost’s poems set to music by Thompson.

“Stopping by Woods on a Snowy Evening” is one of the poems included in the “Frostiana” cycle. The composition captures the reflective and contemplative mood of Frost’s poem, where the narrator pauses to admire the beauty of a snowy evening in a quiet forest. Randall Thompson’s musical setting adds another layer to Frost’s words, enhancing the emotional impact of the poem.

Thompson’s approach in “Frostiana” is characterized by its accessibility and tonal clarity. His settings aim to convey the meaning and atmosphere of Frost’s poetry through the expressive power of choral music. The entire “Frostiana” cycle is a celebration of both Thompson’s skill as a composer and Frost’s enduring contribution to American literature.
