How power distribution works behind the scenes at film and TV sets

Behind every film or TV show is a network of cables, connectors, and distribution boxes working quietly in the background. Lights, cameras, sound, monitors, catering, and editing stations all need reliable power and when you’re on set, even a brief interruption can cause costly delays. Power distribution is the unseen backbone of every production, making sure every department can do its job without worrying about outages or overloads.

At Rubber Box, we’ve spent over three decades designing and building power distribution boxes that keep the entertainment industry running. From small studio shoots to major outdoor productions, our equipment makes sure power reaches every corner of the set safely and efficiently.

Reliable power for every department

Film and TV sets run on tight schedules and heavy loads. Lighting rigs can demand hundreds of amps, sound and camera departments need stable supplies to avoid interference, and trailers or catering areas often run independently. Each element relies on a well-planned power layout.

Our distribution boxes are available in a full range of ratings from compact 16A and 32A units to large 400A systems for bigger productions. Each one is built from solid rubber for maximum durability, double-insulated for safety, and easy to transport between locations. That combination of strength and flexibility makes them ideal for both studio and location work.

Custom-built for unique productions

Every film or TV production comes with its own challenges. One day you might be shooting in a controlled studio with consistent lighting and power demands, and the next you’re setting up in the middle of a field where weather and access are unpredictable. Each of these environments puts very different pressures on your electrical setup. That’s why at Rubber Box, we don’t believe in one-size-fits-all. Our bespoke power distribution boxes are designed from the ground up to meet the specific needs of your production.

You can choose everything from the number and type of inlets and outlets to the level of circuit protection, layout, and even the size and portability of the enclosure. Need a unit that’s weatherproof for an outdoor night shoot? We’ll build it with the right IP rating and materials to handle moisture, mud, and temperature changes. Need a streamlined, rack-mounted setup for an OB truck or studio gallery? We can design that too. Every custom build is tested to the same high standards as our core range, ensuring your power setup is safe, compliant, and perfectly matched to your workflow.

Safety and performance you can depend on

Keeping the cameras rolling isn’t just about convenience; it’s also about safety. Power distribution on set must be managed carefully to protect the crew, performers, and valuable equipment. Electrical faults, overloading, or exposure to moisture can bring filming to a halt or, worse, create serious risks. That’s why every Rubber Box unit is built with safety at its core.

All of our products meet or exceed strict British and European electrical standards, and we offer options for weatherproof and impact-resistant enclosures rated for even the toughest conditions. Every detail from the cable entry design to the circuit protection and insulation is engineered for reliability and peace of mind. When the pressure is on and time is short, you need to know your distro gear won’t let you down. With Rubber Box, production electricians can work confidently, knowing that every circuit has been designed to perform safely and consistently from the first setup to the final wrap.

Fast turnaround and expert support

Production schedules rarely go to plan. Locations change, shooting days get extended, and power demands increase as more equipment is added. When that happens, you need a supplier who can move as fast as you do. We hold a huge range of our most popular power distribution boxes in stock, meaning standard units are ready to go for next-day delivery across the UK.

If your project needs something more specialised, our in-house manufacturing team can build custom solutions quickly and efficiently. We work closely with production managers, electricians, and technical crews to make sure every box arrives ready to plug in and perform. Our team is always available to help plan load distribution, recommend the right connections, and advise on safety and compliance so you can stay focused on delivering great footage instead of troubleshooting power issues.

With over 30 years’ experience supplying power to the entertainment and media industries, we’ve supported thousands of productions across the UK and beyond. We keep more than 10,000 boxes in stock and have built over 80,000 bespoke distribution units, each tailored to meet the demands of different environments and applications.
