Since 1914, the National Electrical Safety Code® (NESC®) has been the go-to safety standard for electric and telecom utility companies of all sizes and ownership of structures. Updated every 5 years, the 2023 edition of the NESC was released 1 August 2022 and will become effective 1 February 2023. Orders for the 2023 NESC are available here.


NESC Table 2503Structure and wire gust response factors GRF

NESC Table 235-5 (Vertical clearance between conductors at supports) states in 1.a., "Communications conductors and cables Located in the communication space shall be 40 (in.) from neutral conductors meeting Rule 230E1. Applying this to Rule 235C2b(1)(a), equates to 30 (in) midspan (75% of 40 in).
