You are designating the circuit 20A, you could use anything 12 gauge and up. This is absolutely fine, there is nothing wrong with this, in fact it’s a good idea if it’s a long run and copper is no object.
What size NM cable should be used on a 20 amp circuit?
12-gauge cable
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 cable should I use for 20 amp?
#12 AWG wire
The perfect wire gauge of a 20 amp breaker is the #12 AWG wire. This is a bigger wire with 25A ampacity and can handle 20 amp current while also satisfying the NEC 80% rule for safety.
How many amps will 6 3 wire carry?
The 60A breaker feeding the 6/3 (I hope it’s copper) will limit the current to the subpanel to 60A per 120v leg. The panel must be rated for a minimum of the size of the breaker feeding it.
What can you use 6 3 wire for?
A 6/3 cable is a 6 AWG cord having three-stranded bare copper conductors, having 101 strands. The cable is generalized and used almost for every purpose, for example, wiring of appliances, circuits of machinery, and lighting.
What amp rating is 6mm cable?
6mm Twin And Earth Current Carrying Capacity
| NOMINAL CROSS SECTIONAL AREA mm2 | REFERENCE METHOD A* (IN CONDUIT IN WALL) Amps | REFERENCE METHOD C* (CLIPPED DIRECT) Amps |
|---|---|---|
| 6mm | 32 Amps | 47 Amps |
How do I choose cable size?
To calculate the Cable Sizing one needs to divide the voltage running through the cable by the target current. For instance, If your wire has a voltage current of 150 Volts and your target is 30 then you divide 150/30. This gives you your target resistance of 5 which is required.
What does NM-B wire mean?
Non-Metallic Sheathed Cable
Type NM-B (Non-Metallic Sheathed Cable) is commonly used for residential wiring of luminaries, devices and appliances.
How many amps will #6 wire carry?
6 Gauge Wire Amps Chart
As you can see, the maximum number of amps a 6 gauge wire can handle is 60 amps. This is the 6 AWG copper wire at 90°C (194°F).
What is the ampacity of 6 3 Romex?
Product Details
| Wire Size | 6 AWG |
|---|---|
| Ampacity | 55 |
What is 6’3 nm b wire?
NM-B is primarily used in residential wiring as a branch circuit for switches, outlets and other loads. NM-B may run in air voids of masonry block or tile walls where locations are not damp.
How many amps is #6 Romex good for?
So #6 NM typically has an ampacity of 55A. Since 55A is not a standard breaker size, it is permissible to protect it with a 60A breaker, provided that the calculated load is 55A or less.
What is 6 AWG wire used for?
6 gauge and larger wires are usually used in the battery and starting systems of vehicles. The most common uses tend to be in the installation of large home appliances such as hot tubs and jacuzzis.
What use is NM cable suitable for?
interior residential wiring
NM Building Cable
Standard NM cable is suitable for interior residential wiring, within ceiling cavities or walls and it is known as NM-8. This type of cable cannot be used in outdoor locations or buried underground. It is approved for use only in dry areas.
Which is better 23AWG vs 24AWG?
A 23AWG cable is 0.57mm wide, while a 24AWG cable is only 0.52mm wide. So the SMALLER the number, the LARGER the physical cable will be, with more copper inside it. To reduce resistance over the cable and achieve better electron flow, the diameter of the Ethernet cable’s conductor must be increased. .
What amperage is #6 Thhn good for?
Allowable Ampacities of Insulated Copper Conductors
| Conductor Size (AWG/KCMIL) | 60°C (140°F) TW, UF | 90°C (194°F) TBS, SA, SIS, FEP, FEPB, MI, RHH, RHW-2, THHN, THHW, THW-2, THWN-2, XHH, XHHW, XHHW-2, USE-2, ZW |
|---|---|---|
| 8 | 40 | 55 |
| 6 | 55 | 75 |
| 4 | 70 | 95 |
| 3 | 85 | 115 |
How far can you run a 20 amp circuit?
You can run a 10 gauge wire up to 85 feet on a 20 amp circuit. If you opt to use this type of wire on a 15 amp circuit, it can run up to 115 feet. After these distances, the circuit will go over the recommended 3% voltage drop. You can run a 12 gauge wire up to 70 feet on a 15 amp circuit.
