What is the biggest cable size we use in the film business?

• A. 4/0
• B. 2/0
• C. 1/0
• D. 6/0

Answer: (A)

In film power distribution, wire size is chosen by how much current you need to carry and how far the run is, balancing ampacity with practicality. The biggest cable size you’ll commonly see on a set is four aught gauge. It offers ample current capacity for large lighting loads and longer runs, while still being manageable to handle, coil, and connect with standard distro gear. Going thicker, like six aught, makes the cable far heavier and stiffer, which becomes a real obstacle in a busy production environment and isn’t usually necessary for typical on-set needs. Larger sizes exist for industrial, fixed installations, but for portable on-set power, four aught is the practical upper limit.
