# How to NOT burn down your set

I will be honest. This is becoming less of a problem every day with all the low wattage fixtures that are being used. It's almost something we don't have to think about at all when using LED lights. But this is still an important topic to understand especially when you are working on a larger set where larger lights are used. What are we talking about? We are talking about understanding how much of a load our lights put on whatever circuit we are using. Every light you plug into a wall will draw a certain amount of power and each circuit only has so much power to give before it literally burns up in your wall. Once you blow a circuit you then begin the time wasting task of tracking down the breaker or fuse box to try and get everything back up and running again. It's always a good idea to breakup your lights onto as many different circuits that you can on any given location. But if you do the math you can be in control of your power draw and know when you are getting close to the max on one breaker and know that you should start adding another. The equation for Amp draw is Amps=Volts/Watts. Your standard household circuit is a 20 amp breaker. That means you have 20 amps to play with. You just put each light wattage into the equation to see how many amps it draws and then when they add up to just under 20 you know it's time to stop adding to that circuit. Now next time you burn something down, don't say I didn't try and teach you.
