There is a significant weight difference between the 14- and 12-gauge ROMEX®. White ROMEX® with two wires, 14-2, weighs 57 pounds for every 1,000 feet of wire.Compare this to the weight of yellow ROMEX® at 82 pounds. for 12-2 and 107 pounds for 12-3 wire.
Is yellow and white wires the same?
US, AC:The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors.
What is yellow Romex wire used for?
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.
Why is Romex different colors?
Romex® Brand SIMpull® NM-B cable is designed for easier pulling, resulting in easier installation. The cable jacket is color-coded for quick size identification; White – 14 AWG, Yellow – 12 AWG, Orange – 10 AWG, and Black – 8 AWG and 6 AWG.
What type of Romex do I need?
The following NEC regulations apply to Romex conductors:
| Wire Gauge or Type | Rated Amperage | Common Uses |
|---|---|---|
| 14-2 Romex | 15 A | Lighting Circuits |
| 12-2 Romex | 20 A | Lighting and Outlet Circuits, refrigerator |
| 10-2 Romex | 30 A | Electric water heater, baseboard heaters |
| 10-3 Romex | 30 A | Electric Clothes Dryer |
What are white wires used for?
The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel. The green wire (or it can sometimes be uncolored) wire is the “ground” wire, it will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
Which wire is hot when both are clear?
If the plastic is clear, the wires in the neutral side are silver while those in the hot side are copper.
Can I use 12 gauge wire on a 15 amp circuit?
Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.
What is the color code for 3 phase wiring?
yellow
Phase 3 – Phase 3 wiring should be yellow. Neutral – Neutral wires should be grey. Ground – Ground wiring should be green, or green with a yellow stripe.
Can you use 12 gauge white Romex?
You should be looking at the circuit breaker to choose the wire size, If a 20 amp breaker it would need 12 gauge if 15 amp breaker 14 would be the correct size but 12 can be used. Almost all nm or romex used to be white so going by the sheath color is not a good way to I’d the size.
Is the yellow wire positive or negative?

Are white wires positive or negative?
Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire is the ground. You may see a copper wire instead of a green wire for the ground.
Why is my white wire hot?
White Wire Labeled as Hot
Sometimes a white wire is used as a hot wirenot a neutralin a switch leg, or switch loop, between a switch and a light fixture.The power is fed up to the light fixture, so there is a hot, neutral, and ground wire already there.
Can I use 12 3 wire for outlets?
It’s 12/3 + ground. Yes, this is allowed. If your needs warrant it, you might consider a multi-wire circuit, which will give you twice the available power. At the very least, do not cut the extra wire short, just push it o the back of the boxes out of the way, so it can be used if needed.
Can I mix 12 gauge and 14 gauge wire?
Can you mix 12 gauge and 14 gauge wire? – Quora. If we are speaking of the US the answer is yes however, even if the supply is 12AWG, the breaker must be replaced with a 15 Amp breaker becuase the 14 awg wire is the smaller load carrying conductor.
Which wire is best for house wiring?
List of Top 10 Wire And Cables Company in India with Revenue:
| Sr.No | Wire And Cables Brand Name | Revenue (Rs. Cr.) |
|---|---|---|
| 1 | Polycab Wires | 8806.91 |
| 2 | Havells India Ltd | 6,720.24 |
| 3 | Finolex Cables Ltd | 3,319 |

Which wire is hot when both are same color?
black
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means.
Does neutral wire have power?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.
What is a switch leg?
The switch-leg portion of electrical circuits controls the flow of electricity to lights or receptacles. The type of circuit wired for a switch depends on where electricity is delivered to the circuit: at a switch or at the light or receptacle.
Which wire is neutral ribbed or smooth?
The ribbed side of the line cord indicates the neutral wire, the smooth side, the hot wire. If we are wiring a line cord plug, the ribbed wire would connect to the wider space or neutral space on the plug itself.
What happens if you reverse hot and neutral wires?
One common issue with electrical outlets is reverse polarity, also known as “hot-neutral reversed.” In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.
