If you’re having trouble, try remembering this rhyme – “If it’s divisible by 6 it’s blue, and the one before it too.” This rhyme only work on 3 phase 120/208 volt panels, but you could substitute yellow if you’re working on a 277/480 volt panel. Normal color wiring for a 277 / 480 volt panel is BROWN, ORANGE, YELLOW – 1, 3, 5, and 2, 4, 6. The same goes for any other voltage coloring scheme you may encounter. The idea is to memorize the circuit number color of the first six circuits in a panel. Circuit 2 is BLACK, which means circuit #20 is BLACK. Use the remainder of 2 as your reference and find what color circuit 2 is. What color is circuit #20? Divide the number 20 by 6. Circuit 5 is BLUE, which means circuit 11 is BLUE. Use the remainder of 5 as your reference and find what color circuit 5 is. What color is circuit #11? Divide the number 11 by 6. Using the panel or layout above find what color circuit 6 is. Circuit 6 is BLUE, which means c ircuit number 24 is BLUE. Since 6 divided evenly, circuit #24 will be the same color as circuit #6. What color is circuit #24? Divide the number 24 by 6.

If there’s a remainder, use that to determine the wire color. If a number divides evenly by 6 then that circuit will be the same phase color as the number 6.

The most important thing to remember is this: When using the rule of six you will reference the first six circuits, their phase and color. Then click the X that appears on the left upper corner of Circuit Coder 1.0 to perform the uninstall. Click and hold Circuit Coder 1.0 icon with your mouse button until it starts to wiggle. Open up Launchpad, and type Circuit Coder 1.0 in the search box on the top. Normal Wiring for a 120 / 208 V 3 Phase Panel Option 2: Delete Circuit Coder 1.0 in the Launchpad. Circuits are labeled with the odds on the left and the evens on the right. This can help keep you on track, but here’s how you can do it mentally and look like an awesome apprentice!Ī 3 phase panel wiring is A, B, C – left to right- and top to bottom. It’s easy to stick a piece of colored tape on circuit breaker identify the wiring color for the color scheme that’s in use. Usually I make up temporary panel schedule on piece of notebook paper before I start pulling in new wires.

This method of dividing a circuit number is sometimes easier than carrying around a electrical wiring color code chart.

How To Identify Circuit Number Colors in a 3 Phase Panel Yes, its actually quite simple. Divide any circuit number by six and you can figure out the color of a wire you need.Īnd now I’m going to teach you to be a circuit number ninja without using a color coded wiring chart. With a decoder only four control lines are needed.Circuit number colors in a 3 phase panel are really easy to identify once you learn a trick. It’s called the Rule of Six. A circuit needing to select among sixteen devices could have sixteen control lines to select which device should “listen”. Usually it is easier to design ladder logic from boolean equations or truth tables rather than design logic gates and then “translate” that into ladder logic.Ī typical application of a line decoder circuit is to select among multiple devices. For an eight-bit adder we only know how to sum eight bits by summing one bit at a time. If you do it might look something like this:įor some logic it may be required to build up logic like this. You might also consider making a 2-to-4 decoder ladder from 1-to-2 decoder ladders. In a similar fashion a 3-to-8 line decoder can be made from a 1-to-2 line decoder and a 2-to-4 line decoder, and a 4-to-16 line decoder can be made from two 2-to-4 line decoders. Replacing the 1-to-2 Decoders with their circuits will show that both circuits are equivalent. An alternate circuit for the 2-to-4 line decoder is: Larger line decoders can be designed in a similar fashion, but just like with the binary adder there is a way to make larger decoders by combining smaller decoders. Developed into a circuit it looks like the Figures below.
