Question: Not understanding the conductor configurations. E.g. 12-6 it seems like it has 5 Hots(black and red) listed.

You're right, conductor configurations can be confusing! Let's break down what something like "12-6" means, and why you might be seeing 5 "Hots" listed.

Understanding Conductor Configuration Notation (Like 12-6)

The "12-6" notation typically refers to the number of conductors within a cable, and their AWG (American Wire Gauge) size. It's usually described like this: First Number (12)

Represents the AWG size of the individual conductors. So, in "12-6," the conductors are 12 AWG. A smaller AWG number means a thicker wire and a higher current carrying capacity.


Second Number (6)

Represents the number of conductors within the cable. So, in "12-6," there are six conductors.

Therefore, 12-6 cable has six 12 AWG wires inside.
Why You Might See 5 "Hots" Listed (Misunderstanding Colors and Function)

The confusion probably arises when you look at the color codes associated with the individual wires within a cable. Here's where things get tricky:1. Ground (Green or Bare)

Every cable will have a ground wire. It's ALWAYS green or bare (uninsulated).2.

Neutral (White or Gray)

A neutral wire will also be present. It's designed to carry the return current back to the source.3.

Hot (Various Colors)

"Hot" wires carry the electrical current from the source to the load (e.g., a light fixture, appliance). The colors can vary, but the standard ones are black, red, blue, and sometimes yellow or orange.

Common Configurations and How They're Used


To understand how to interpret configurations and identify each wire's purpose, here are some common cable types and their typical uses: 12-2 with Ground

(Two 12 AWG conductors + Ground)
Black (Hot) White (Neutral) Green or Bare (Ground) Used for standard 120V circuits like lighting and receptacles.

12-3 with Ground

(Three 12 AWG conductors + Ground) Black (Hot) Red (Hot - used for a second circuit or as a switch leg) White (Neutral) Green or Bare (Ground) Used for three-way switches, ceiling fans with lights (where the light and fan are switched separately), or 240V circuits (if properly wired).

12-4 with Ground

(Four 12 AWG conductors + Ground) Black (Hot) Red (Hot) Blue (Hot) White (Neutral) Green or Bare (Ground) Used for more complex switching arrangements, or for certain types of appliances requiring multiple circuits.

Now, to address your "5 Hots" concern...


You're probably misinterpreting the application or the labeling you're seeing. If you are reading this in a electrical supply book, sometimes they will list out the wire colors. If you see a configuration with 6 wires, it would have a ground, neutral, and then 4 different color hots.

Key Takeaways
"Hot" is a function, not a color. While black is very common for hot, other colors are used. Never assume. Always check the specific diagram for the application you are working with. Consult a qualified electrician. If you're unsure, it's ALWAYS best to get professional help. Electrical work can be dangerous.To give you a more specific answer, please provide more details: Where are you seeing the configuration information? (e.g., a specific product listing, a wiring diagram, a textbook, etc.) Can you copy and paste the specific listing or diagram you're seeing?* What application are you trying to use this cable for?
