When it comes to electrical wiring, Romex is an essential tool that helps ensure the safety of your home’s electricity.
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.
Here AVG stands for American Wire Gauge and is the standard measure for wire size.
So, no you cannot mix yellow and white Romex as it would be confusing to determine what gauge wire was used in the circuit.
The NEC specifically states that only one color of NM cable should be used on any given circuit. This helps ensure safety by allowing electricians and homeowners to quickly and easily identify the size of the wire being used.
What is Yellow Romex?
Yellow Romex is most commonly used for 12 AWG wiring such as in a kitchen or bathroom.
Yellow color-coded cable sheathing encloses 12-gauge wires.
This 12 -gauge wire is called 12/2 when two insulated wire conductors are included.
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.
12-gauge wire is the minimum requirement for outlets on a 20-amp circuit.
12-gauge wire can be used for outlets on both 15 and 20-amp circuits.
When Can White Romex Be Used?
It is commonly used for outlets, lights, and smoke detectors in the home.
This 14-gauge wire is called 14/2 when two insulated wire conductors are included and 14/3 with three wires.
You can use 14/2 Romex cable anywhere you can safely use standard 14/2 cable.
This means that 14/2 Romex is capable of power outlets that are on a 15-amp circuit.
If you are wiring outlets on a circuit with amperage above 15 amps, you’ll need to use a heavier Romex cable to comply with the electrical code.
White Romex can also be used in dry indoor locations where there is no potential for moisture or damage to the wire.
What Is The Difference Between 12-gauge(Yellow) and 14-gauge (White) Wires?
12-gauge wire can safely carry larger amperages without overheating and running the risk of starting a fire.
It is thicker than 14-gauge wire.
Long stretches of wire can transmit power with less possibility of a voltage drop thanks to the heavier 12-gauge wire.
Although 14-gauge is equally suitable for many residential wiring purposes, 12-gauge is rated for heavier duty.
Residential cables will have 3 wires in both the 12 and 14-gauge varieties.
As they conduct electricity, the first two wires are “hot.” They will wear black and white jackets, respectively.
The ground wire is the last. It will either be green-jacketed or bare copper.
Does Mixing Yellow And White Romex Unsafe?
Yes, Because different wires are used on different amp circuits, and mixing them will make electric hazards.
14-gauge wire( White) is unsafe to use for outlets on a 20-amp circuit because it is not rated for the higher load of a 20-amp circuit.
The 20-amp circuit is best to use with 12-gauge wire( Yellow) or heavier.
It is not safe to mix yellow and white Romex in the same area, as this could lead to a potential safety hazard due to incorrect wiring.
So, if you are wiring your house with Romex, make sure you keep the colors separated according to their gauge size.
Mixing yellow and white Romex in the same area is not only dangerous but also illegal according to the NEC code.
In conclusion, due to safety reasons, it’s important to make sure you use the correct size and color of Romex when wiring your home.
It is best to always consult a qualified electrician when dealing with electrical wiring.
Make sure to use the right color of Romex for each circuit to ensure maximum safety and compliance with the NEC code.
Can You Use Romex 14/2 Wire For Outlets?
Yes. Romex 14/2 wire which is a white color can be used for outlets on a 15-amp circuit.
If the outlet is 20-amp then the 14/2 is not sufficient.
Then you should use 12-gauge wiring or heavier to comply with the NEC standard.
When wiring outlets, make sure you use the correct size and color of Romex for each circuit.
If you use 14/2 wire on a 20-amp circuit, your devices will likely overheat or cause a fire hazard.
Before wiring and outlet make sure by checking the breaker box or old wiring to determine what size wire and color you should use.
And always consult a qualified electrician who is knowledgeable in the correct methods of wiring your home.
Can You Use Romex 14/2 Wire For Lights?
Yes. One of the best uses of 14/2 wires is to wire lightbulbs.
You can use a 14/2 wire to power the light as long as it is on a 15-amp circuit.
Just make sure the bulb only needs 15 amps or less. 14/2 wire is frequently used in homes for built-in lighting.
If your light needs more than 15 amps, you’ll need to wire it to a more powerful circuit with a wire heavier than 14/2.
14/2 is seldom used for outlets because it cannot power certain appliances and tools.
Where Can Use Romex 12/2 Wire?
You can use Romex 12/2 wires on any Outlet that uses 20-amp circuits.
Most home builders use 12-gauge wire to connect all outlets to 20-amp circuits because some equipment like AC units, shop vacuums, and power tools need that much power.
These larger appliances simply cannot be powered by 15-amp connections which are 14/2 Romex wires.
If you opt to change your circuit breaker and go up to a greater amperage, just keep in mind to pick outlets and cables( Romex 12/2) that are rated for 20 amps.
What Gauge Wire Should Use For Outlet?
Consider the following when choosing between 12-gauge and 14-gauge wire for your outlets:
1. Outlets on a 20-amp circuit must have at least 12-gauge wire.
2. Outlets on 15- and 20-amp circuits can both use 12-gauge wire.
3. Use of 14-gauge wire for outlets on a 20-amp circuit is dangerous.
4. Only outlets on 15-amp circuits can use 14-gauge wire.
5. You can easily increase the outlets and circuit breaker to 20 amps in the future by using 12-gauge wire for all of the outlets.
6. If a circuit is wired using 14-gauge, increasing its amp capacity to 20 amps is exceedingly challenging.
Just keep in mind to adhere to all safety precautions when connecting electrical outlets or other fittings. When in doubt, get in touch with a certified electrician.
Whether you’re rewiring outlets in your house or installing electrical lines as part of a new building, it’s critical to select the right Romex wire gauge for the task.
When a larger wire is needed, using a lesser wire gauge (like 14 gauge) might lead to outlets that don’t work properly or possibly an electrical fire.
Before deciding on the wire size for your project, carefully review these instructions for your safety.
Never mix and match different wire sizes on the same circuit.
Always use the appropriate wire gauge when wiring outlets and follow all safety precautions to avoid potentially hazardous conditions in your home.
Remember, it is best to always consult a qualified electrician when dealing with electrical wiring.
