BTS and Breakdown with colorado_gaffer Swipe 👉🎬 📒Gaffer's note by Tyler Kaschke 👇 Today I’m going to give you practical tips that you can use on set when deciding how much power you’ll need to supply your lights. Let’s dive a little deeper into amps. The amperage of a circuit is important to consider because all components of an electrical distribution system must have enough capacity to carry the current. If your cables are too small, they will heat up and could start a fire. Ain’t nobody got time for that. To calculate the amperage of your lights, divide the wattage by your voltage. In the US on a household circuit, that would be 120V. For example, a 500W light on a 120V circuit pulls 4.2A. That same light on a 240V system would be 2.1A. Easy, right? Well, if you’re like me and easily confused by numbers greater than 100, there is a quick way to do that calculation in your head. Instead of dividing by 120, divide by 100. Dividing by 100 over estimates the amperage and builds...
