FAQs

What do the diagonal lines in wiring/raceways indications represent?

The number of diagonal lines indicates the number of #12 AWG conductors. Absence of diagonal lines indicates #12 AWG plus #12 AWG ground unless noted otherwise.

How are homeruns to panels described on the drawings?

The number of arrows indicates the number of 20A, 1-pole circuits to the panel, unless otherwise noted.

What reuse requirements are stated for lighting during temporary lighting?

Existing surface fluorescent fixtures are reused for temporary lighting, and emergency battery units with integral heads are also reused for temporary lighting (typical).
