Question:

Hello and thanks for the NEC work. Based on the 2020 NEC, is a Service Entrance disconnecting means required at a temporary power pole rated 60 Amps and installed for residential single family construction?

Michael Dowdy

A

Answer:

Hi Michael,

Thanks for the question. Article 590 provides the requirements for temporary installations. Section 590.2(A) indicates that except as specifically modified in this article, all other requirements of this Code for permanent wiring shall apply to temporary wiring installations. Section 90.3 is also in play here and indicates that the Code is divided into the introduction and nine chapters. Chapters 1,2, 3, and 4 apply generally. Chapters 5, 6, and 7 apply to special occupancies, special equipment, or other special conditions and may supplement or modify the requirements in Chapters 1 through 7 A temporary construction electrical service is required to have a service disconnecting means in accordance with Part VI of Article 230.
