Price chart for small construction site electrical distribution boxes

Small construction site electrical distribution boxes typically range from $150 to $500 depending on features, capacity, and supplier.

Overview

Construction site electrical distribution boxes, also known as site boxes or temporary power enclosures, provide safe and reliable electricity for tools, lighting, and other temporary equipment on construction sites. They are equipped with circuit breakers, differential switches, and often emergency stop buttons to prevent overloads and electrical hazards. These boxes are designed to be durable, weatherproof, and easy to handle, making them suitable for outdoor use in harsh environments.

Price Range

Basic small site boxes: For single-phase, low-capacity units suitable for small construction sites, prices generally start around $150–$250. These units typically include a few standard sockets and basic protection features. Mid-range units: More robust boxes with additional circuits, higher amperage, or three-phase capability can cost $300–$500.

These often include waterproof enclosures, enhanced safety features, and pre-wired configurations for easier installation. Premium or customized units: For specialized applications, such as boxes with smart monitoring, remote control, or integration with building management systems, prices can exceed $500, depending on specifications and certifications.

Factors Affecting Cost

Material and durability: Boxes made from thermoplastic, fiberglass, or sheet steel with IP65–IP67 ratings are more expensive due to weather and impact resistance. Number of circuits and sockets: More circuits and higher amperage increase the price. Safety features: Integrated circuit breakers, differential switches, and emergency stop buttons add to cost.

Supplier and brand: Well-known brands like Schneider, Eaton, or PCE may charge a premium for reliability and compliance with European or IEC standards. Installation and accessories: Pre-wired units or those with mounting options may have higher upfront costs but reduce labor expenses.
