Can I mix 12 and 14 gauge wire?
Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too.
There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire..
Is code for electrical wire?

Which is the positive wire?
The positive wire, also commonly called the hot wire, will typically be black in color. It is the source of the electricity. The electrical current travels from the outlet or other power source on the positive wire, so if it is plugged in anywhere, it should be considered a live (and dangerous) wire.
What type of wire is yellow?
Yellow Sheathing Yellow color-coded cable sheathing encloses 12-gauge wires. Yellow 12-gauge cable is typically used for 20-amp circuits that power general household outlets used for a variety of plug-in appliances. Dedicated appliance circuits also call for 20-amp circuits in most cases.
What voltage is yellow wire?
480 VACWiring Colors | Electrical Wire Color Coding Standards The USA has their own wiring colors for electrical circuits, black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC.
What is the color of positive and negative wire?
Positive – The wire for the positive current is red. Negative – The wire for the negative current is black.
What is the blue wire called?
neutral wireThe blue wire is known as the neutral wire and its job is to take electricity away from an appliance. The brown cable – known as the live wire – actually delivers electricity to your appliance. Together, these two wires form a complete electric circuit.
Can you use 14 gauge wire on a 20 amp breaker?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. … Just use the side terminals.
What is the difference between yellow and white electrical wire?
The National Electrical Code (NEC) says that white or gray must be used for neutral conductors and that bare copper or green wires must be used as ground wires. … Yellow 12-gauge cable is typically used for 20-amp circuits that power general household outlets used for a variety of plug-in appliances.
What happens if you reverse hot and neutral wires?
If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.
What color wires go together for a ceiling light?
Connect the white wires (neutral wires) from your fan and ceiling together. Connect the green wire to your household ground wire (copper/bare wire). Connect the black wires together. Lastly, connect the blue wires together, or the blue wire to the black wire for lights.
How do I identify electrical box wires?
Tip #1: An easy way to identify the wires in your wall box is by looking at the color. Tip #2: The Load wire is usually coming from the top of the box. The Line wire is usually coming from the bottom of the box. Tip #3: Before removing the switch, test each wire with a voltage tester.
What Colour wires are live?
The live wire is brown in new systems and red in old systems. The neutral wire is blue in new systems and black in old systems.
Is yellow wire live or neutral?
Blue and Yellow Electrical Wires Blue and yellow wires are most commonly found in commercial buildings and are used as the live wires pulled through a conduit. These wires carry power but aren’t used in typical outlet wiring.

What Colour wire goes to L and N?
The N is for the neutral side or the white wire, and the L is for the load side, the black wire.
What is 14 gauge wire used for?
14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps.
What color is the common wire?
WhiteWhite. The “common” is the “neutral” or “ground” wire, depending on the type of circuit. In normal US residential wiring, you’ll have a black “hot” wire, a white “neutral” or “common” wire, and a green or bare “ground” wire.
