Requirements for Temporary Power Distribution Boxes at Second-Level Construction Sites

IRC 2024 Chapter 36, drawing from NEC Article 590, requires that all 120-volt, 15-ampere and 20-ampere receptacle outlets on construction sites be GFCI-protected with no exceptions. Temporary power may be supplied by a utility service connection, a generator, or a combination. Why Temporary Power Systems Are Critical on Job Sites Construction sites are. Hydraulic power packs that feed hydraulic splitters or concrete pulverizers impose characteristic requirements on the construction power supply: high inrush currents, continuous power delivery, and temporary peak loads. Proper sizing prevents voltage dips that can noticeably reduce tool. Effectively managing temporary power safety on any construction or demolition job site is a non-negotiable responsibility for every qualified electrician. Not only do they keep work moving quickly and efficiently, they ensure worker safety and code compliance.
