What Size Wire Should You Use for Your Recessed LED Lights
When it comes to installing recessed LED lights, choosing the right wire size is crucial. You don’t want to end up with wires too thin that could heat up or ones so thick that they look like they’re training for a bodybuilding competition! Fear not, my friend, for I’m here to shed some light on the correct wire size for your recessed LED lights.
Understanding the Wire Sizing Game
Before we dive into the specifics, let’s have a quick rundown on wire sizing. Wire gauge is the measure of a wire’s diameter, and the lower the gauge number, the thicker the wire. It’s like measuring the waistline of wires—if they even have waists!
Sparking the Right Connections
When dealing with recessed LED lights, the National Electrical Code (NEC) is our trusty guide. According to the NEC, the wire size you need depends on the wattage of your LED lights and the length of the wire run. Heed their wisdom, and you’ll be shining in no time!
Calculating the Wire Size for Your Needs
To determine the perfect wire size, you’ll have to do some simple math—a little more exciting than counting sheep. First, find out the total wattage of your LED lights. Multiply this by 1.25 (because we’re considering a 25% safety margin). Next, calculate the length of your wire run, including the way back. Divide this length by 2 (since the power flows there and back, like a boomerang, but less dangerous).
Drumroll, Please! The Wire Size Chart
Based on your calculations, consult this wire size chart to choose your ideal wire size:
