What is 10-2 Romex used for?
The following NEC regulations apply to Romex conductors:
| Wire Gauge or Type | Rated Amperage | Common Uses |
|---|---|---|
| 10-2 Romex | 30 A | Electric water heater, baseboard heaters |
| 10-3 Romex | 30 A | Electric Clothes Dryer |
| 6/3 Cu Range Cable | 50 A | Range, Heatpump, On-Demand Electric Water heater |
| 2 Gauge Copper | 100 A | Central Electric Heat |
How far can you run 10-2 wire?
The size of the wire you run to your shed depends on how far away it is and whether you use 120V or 240V. If your shed is 50 feet from your breaker box, you can use 10/2 AWG UF-B wire for a 120V circuit up to 20A. This will allow you to run multiple machines at the same time while providing light to your shed.
Can I use 10-2 wire 220V?
A 30 Amp circuit is needed for most 220V tools. You will need to run a 10-2 to the outlet. 10-2 copper wire is usually good for up to 40 Amps on start loads and 35 Amps on constant load.
What is a 10 3 wire?
10/3 cable is designed to power 220-volt outlets, such as the four-pronged outlets used to power electric dryers, air conditioners, and ranges. It is typically used in residential wiring and is designed to run on a 30-amp circuit. 10/3 cable contains 3 live wires as well as a ground wire.
Can I wire my house with 10 2 wire?
The number 10 wire is good for 30 amps. That is max. Yes you can use it for a smaller breaker.
Can I use 10 2 wire for an outlet?
Yes. Just use a single polr breaker and connect the white to the neutral bar and black to the breaker. Ground remains as is. I would snuggest a back wired* commercial receptacle because it would be a son-of-a-gun to get a #10 wrapped around a screw.
What size wire do I need to run 300 feet?
for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit.
What kind of Romex do I need for 220?
No such thing a 220 Romex in the US. They do have 240 volt Romex in Canada but it is not what you have drawn. In Canada under CEC a 240 volt only supply use a Romex cable with red and black with ground but no white. No distinction is made in the USA code.
Can I use 10 3 wire for a stove?
A 10/3 wire is the appropriate wire to use for a standard electric stove that runs on a 240-volt circuit.
How many amps can 10 3 wire carry?
30 amps
What Type & Gauge of Wire Should I Use?
| Type NM-B (Typical Indoor Applications)* | ||
|---|---|---|
| 10/3 with ground | Apartment size Range – up to 30 amps Built-in Single Ovens – up to 30 amps | Electric Dryer – up to 30 amps |
| 10/2 with ground | Electric Wall Heater – up to 30 amps | |
| 8/3 with ground | Double Oven Range – up to 45 amps |
Can I put a 20 amp breaker on 10 gauge wire?
Yes, you can use 10 AWG copper conductors with a 20 ampere breaker. The smallest size conductors you could use with a 20 ampere breaker, are 12 AWG copper conductors. There’s no problem using larger conductors, other than cost to you, and difficulties associated with working with thicker conductors.
