This also refers to the thickness of the wire and is the one to identify the current that a wire can handle. The wires are the ones that you will connect within or inside the wire nuts. Since wire connections come in different sizes, the wire connectors are also designed to accommodate these different wire sizes.Ī wrong wire nut size-either too big or too small for the number of wires you’ll connect-can lead to a weak connection. Like its yellow-colored counterpart, you can also use the red wire nut for copper-to-copper, aluminum-to-aluminum, and copper-to-aluminum connections. If you need to get three #10 wires together, this is the wire nut of choice. The red wire nut capacity can accommodate up to 2 #10 and 2 #12. The last among the wire nut colors is red. ![]() You can use these wire nuts for copper-to-copper, aluminum-to-aluminum, and copper-to-aluminum connections. The yellow wire nut is your best choice if you need to connect four #14 and one #18 wire. Usually, orange wire nuts are used to connect fans and lights to switch wires. It can hold up to 4 #16 and 1 #20 AWG wires. On the other hand, this bright wire nut is best if you need to connect at least one #18 and one #20 wire size. This is the preferred wire of choice for ballast wire connections and is considered the largest wire nut. The blue wire nut capacity can hold up to three 16 AWG solid wires. The blue one is slightly bigger than the gray wire nut. The gray nut is usually intended for fine-stranded wire applications. The gray wire nut can hold up to two 22AWG stranded wires or two solid 16AWG wires. When it comes to wire nuts, you need to know two things-the wire nut color code and wire nut sizes.Įach of the colors, namely gray, blue, orange, yellow, and red, and the different sizes are intended to handle different amounts of gauge sizes and wire types. ![]() In this article, we’ll tell you exactly how to read these wire nut sizes charts, how to properly connect them, and answer any other related questions. If you don’t have much experience working with wire nuts, you can use a wire nut size chart.Īll you have to do is review both the size (or gauge) and number of cables you are working on and then cross-reference these to the correct wire nut sizes.Īccessing a wire nut size chart is one thing, but using the right nut for the job is crucial. There are a variety of types and sizes, and equipping yourself with the correct ones can lead to a lot of guess-work. These handy connectors are also called winged wire nuts, twist-on-connectors, and Marettes. Wire nuts connect electric cables for in-home, commercial, and industrial wiring. This is where wire nuts come in and can help keep you straight. You usually can’t afford to make mistakes when working on an electrical project. And on top of that, getting them to STAY together security is a must. It’s easy to join the wrong wires together for one thing. the client was the wife of a eye surgeon & had they been that destitute I would have gifted them 4 extra lamps.Connecting electrical wires can be a little tricky, I get it. Most of my folks added their initials to the date. installed - with magic marker - on every lamp we installed. Also, after one of my residential clients called (less than 24 hrs after a new 4 lamp fixture w/ 4 new lamps, all same brand) to complain of only 1 lit lamp and the arriving Journeyman found 4 lamps of 3 different brands, all with black ends, we all started marking the mo. 'tis a lot easier & less expensive to replace lamps than ballasts. Sure the client ate a second (at the time $1.84) 4' lamp - BUT 1 new & 1 old T-12's stressed out the ballasts & caused premature ballast failure. As an aside, until the electronic ballasts debut, I always had my people replace lamps in pairs (regardless if only one was dark). Needless to say, I sadly felt the need to let the re-use guy go. Not a single nut fell off in the 2000+ fixtures where the guys used new. call outs I found these re-used nuts rolling around inside the fixtures. One of my guys decided to re-use nuts (thinking to increase my bottom line). ![]() Power leads were replaced with Tan, (BTW, I had the crew replace ALL wire nuts with new to alleviate the chance of call backs as working over the lanes required care. When doing a switch to electronic ballasts in 6 Bowling Alleys and 1 Office bld'g I did utilize a bunch of the Orange ones. The Tan (having a broader range of conductor size they can accommodate) are my preference.
