Power distribution box in the film crew

Film crew power distribution boxes safely manage and distribute electricity on set, providing reliable, monitored power for lighting, cameras, and other production equipment.

Purpose and Function

Power distribution boxes, often called distro boxes, are essential for film and TV productions to safely distribute electricity from a main source to multiple devices. They allow lighting rigs, cameras, sound equipment, trailers, and catering areas to operate simultaneously without overloading circuits. These boxes are designed to handle high loads, prevent electrical faults, and ensure crew safety in both studio and location environments.

Key Features

Amperage Ratings: Available in a range from compact 16A and 32A units to large 400A systems for major productions. Circuit Protection: Many boxes include GFCI outlets, RCBOs, and overvoltage protection to prevent equipment damage and electrical hazards. Portability and Durability: Housings are often weatherproof, impact-resistant, and made from materials like solid rubber or shock-mounted flight cases for easy transport.

Monitoring and Control: Advanced units provide real-time voltage and current monitoring, relay-controlled switching, and logging capabilities to track power usage and prevent overloads. Connector Options: Boxes may include Cam-Lok, Bates, stage pin, or 19-pin connectors to match various equipment requirements.

Types of Distribution Boxes

Portable Distro Boxes: Lightweight and compact, ideal for location shoots or temporary setups. Examples include Motion Lab and Lex boxes with multiple duplex outlets and color-coded inlets.

High-

Capacity Units: Designed for large-scale productions, these can feature 48–72 channels, 400A powerlock inputs, and auxiliary outlets for complex setups.

Custom/

Bespoke Boxes: Tailored to specific production needs, including weatherproofing, IP ratings, and specialized layouts for OB trucks or outdoor shoots.

Safety Considerations

Always ensure the distro box is rated for the total load of connected equipment. Use boxes with built-in GFCI or RCBO protection to prevent shocks. Weatherproof and rugged designs are critical for outdoor shoots to protect against moisture, mud, and temperature extremes.

Proper cable management and labeling help prevent accidental disconnections or overloads.
