So let’s get started with 10/3 Romex Wire
Introduction to Romex Wire
It is important to know the idea of the Romex wire first. Romex wire electrical wiring brand that is mostly used in residential and commercial uses. There are many conductors in this cable with protection sheets made of non-metallic material. This desing offers simple use and safety that make this brand wire best for electrical uses
What is 10/3 Romex Wire?
Definition
10/3 Romex wire is Romex wire and has the best construction features and electrical parameters. The “10/3” comes with a gauge of the wire and conductors that the wire has. Wire has individual conductors each one has 19 gauge thickness and has a ground wire that makes it 4 wires in the sheath
Construction and Composition
The 10/3 Romex wire has three copper conductors each one is 10 gauge thickness. These conductors are color-coded for easy identification normally red black or white for these three conductors and green for ground wire.
Applications of 10/3 Romex Wire
- Normally used for appliances that needed 20 volts and 120 volts such as dryers. Air conditioners need 240 volts power supply and an additional conductor is unnecessary
- Some more applications are
- Interior walls.
- Garages.
- Above-ground surface wiring.
- Outlets.
- Light fixtures.
- Ceiling fans.
- Electrical panels.
- Light switches
Advantages of 10/3 Romex Wire

- Pool pump
- Electric car charger
10 2 or 10 3 Wire for Air Conditioners
The first number in wire denotation is the gauge or thickness of the wire, and the 2nd number is non-grounding conductors or wires in the cable.
These cables also come with grounding conductors, that are not added in numbers. Both 10/2 and 10/3 come with ten gauge wire, which is best for some AC systems.
While 10/3 wire comes with 4 conductors and is used in devices that need 240 volts and 120 volts like dryers. Most AC systems have 240 volts power supply and extra conductors are not needed. Since 10.3 wire has not benefits for those who need wiring for ac system. So using 10/3 wire can cause high costs.
Difference between 10-2 vs 10-3 wire
10/2 and 10/3 basic difference is the number of conductors. The 10/2 wire has two conductors and the 10/3 has 3 conductors.
10 is the AWG wire size used in these two wires and is a calculation of wire thickness. 10 AWG is thick and can handle a 30 amp current. The second number 2 to 3 is several conductors in the cable. With conductors, the cable also has a ground wire
Their applications are mostly the same but 10/3 wire is also used where high power is a need like, like ovens, and air conditioners. 10/2 wire used for low-power devices light fixtures, outlets, and switches.
differences between 10/2 and 10/3 wire:
Feature | 10/2 Wire | 10/3 Wire |
---|---|---|
AWG Size | 10 | 10 |
Number of Conductors | 2 | 3 |
Maximum Current Carrying Capacity | 30 amps | 50 amps |
Typical Applications | Light fixtures, outlets, switches | Electric dryers, ovens, air conditioners |
Why are Four-Pronged Outlets so Special?
The older wiring system has 3 ronged wires. These outlets have two hot wires and neutral aires with ground wire. If there is an issue with the device current passes through the neutral wire and the device casues shock.
4 pronged outlets have a third pron that is connected with ground wire. This wire gives a safer path for current to flow if there is a fault in devices. It saves from electrical shock.
4 pronged outer used by NEC for electric dryers and ranges. In older wring that has three-pronged now must have to replace with 4 pronged outlets if you have an electric dryer or range.
Advantages of four-pronged outlets:
- It supported new devices
- It used for operating dryers and ranges
- For protection from shock, it has a dedicated ground wire
What is the Diameter of 10/3 Wire?
The diameter of a 10/3 wire is about 0.1019 inches. it is the value of each three conductors in the cable. The total die dia is 0.66 inches. The 10-in-wire name defines the thickness of the wire defined by AWG. The 10 AWG wire is larger and thicker and carries a 30 amp current.
Is 10/3 Wire Heavy Enough for a Dryer?
Yes, normally we have used the 10/3 w/ground, NM-B, Romex, copper, Thhn. It is good for 30 amp 240-volt duer according to NEC
Voltage Drop of the 10/3 Cable
The voltage loss of a 10/3 cable is defined on length, current in cable, and resistance of the cable. This formally used to measure voltage loss
Voltage loss= resistance x current x length
As we know resistance of 10/3 cable is about 0.003937 ohms per foot. So100-foot 10/3 cable and the current flowing through the cable is 30 amps, the voltage loss is
voltage drop = 0.003937 ohms/foot x 30 amps x 100 feet = 1.1 volts
According to NEC voltage loss for this cable not be more than three percent. So here voltage are according to NEC
Here are some points to reduce voltage loss in a 10/3 cable:
- shortest possible length of cable.
- larger wire size.
- Avoid using cable that is damaged or old.
Can 10/3 Wire Be Run Underground?
Yes, 10/3 wire can be run underground. The underground cable is made of thick gauge wire and has a protective outer cover that is resistant to moisture and sunlight. it must be buried 18 inches deep according to NEC. There must be a conduit used to protect the cable in the ground. Conduit protects cable from damage and corrosion is made of plastic pipe or metals
Here are some points for running 10/3 wire underground:
- correct cable use
- Label the cable so that you use it.
- Bury the cable at least 18 inches deep.
