How to Add an Electrical Box for Bathroom Lights — powered by ehow
Let’s talk about how to install an electrical box for bathroom lights. Now the first thing you’ll want to do is to remove the sheet rock from the wall that you are going to put the light on. Now generally speaking this would be over your sink area where the mirror is going to be. Now we have our box mounted here at an optimal height and what we want to do is run our 14/2 with a ground which is good for 15 amp up into our junction box and then we would take some tacks and tack this dude down. Now, when you are mounting your box, you need to be mindful of where the top of your mirror is and you want it to be far enough up to where the light fixture does not set on top of the mirror after you’ve replaced it but it’s very easy. All you’ve got to do is get your feeder wire back to the switch to where you can switch it off and on.

Let’s talk about electric insulation & low voltage insulating materials. Now, when you start talking about low voltage wiring in the electrical industry, the National Electrical Code states that any wiring less than 600 volts is considered to be low voltage. Now, I have some different versions of low voltage wiring insulating material right here. This is a version of a stove cord, or an extension, it’s got an outer casing on it, it’s also got some paper wrapping on the inside of the cord that keeps the wire somewhat separated. And then, each individual number ten wire has its own insulation. In our junction box here, which is also a 30 amp sub panel, we’ve got a number ten Romex set in here, which is almost the same version as a THHN. This is a heavy duty plastic material, if you will, it’s petroleum based. The main thing that you want to look for, is make sure that you don’t have any gaps or cuts in this insulation. If you do, it’ll cause sparking and arcing and eventually become a fire hazard. Always you know, leave yourself a fair amount when you’re making your joints or you’re making your connections. But never take more than three-eights of an inch away from any connection.
