8 Gauge Wire Amp Rating
#8 Gauge THHN Copper Stranded Wire is the most popular single conductor copper wire we carry and is RATED FOR 55 AMPS @ 90°C. Our 8 AWG THHN Stranded Wire is THWN-2 dual rated, in stock, and can ship immediately.
What can I use 8 2 wire for?
Applications: Non-metallic sheathed NM-B cable is used in normally dry installations in residential wiring, as branch circuits for outlets, lighting and other residential loads.
How many amps can 8 wire?
According to NEC, 8-gauge copper wire can handle a maximum of 40-55 amps while 8 gauge aluminum wire can handle a maximum of 30-45 Amps. 8 gauge wire can withstand 40 – 55 amps.
Does 8 2 wire have a ground wire?
It will have a ground bus.
How far can you run 8 gauge wire for 30 amps?
For 30 amp service 100 feet away you would need a wire that can handle at least 45 amps. Luckily, the #8 AWG wire has a 50A ampacity. You can use the #8 AWG wire for sub panel 50 feet, 100 feet, and even 150 feet away.
What size wire is needed for 80 amps?
80-amp service requires a 2-gauge wire. If you exceed 80 amps, you should jump to 1 gauge. The next size after 1-gauge is 2/0, followed by 3/0. It should be noted that you can only use 2 or even 3-gauge wire if the material is copper.
What color is 8 2 wire?
8/2 Black Stranded Romex SIMpull CU NM-B W/G Wire.
What size wire is needed for 50 amps?
50 AMP Wire Size
For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances. However, a kitchen oven can alone require 50 amps. Many electric dryers also require a 50 amp breaker.
Can neutral wire be bare?
3: The grounded neutral conductor shall be permitted to be a bare conductor if isolated from phase conductors and protected from physical damage.
What size breaker do I need for 8 gauge wire?
Since 8 gauge wires can capably carry 40 amperes, we can determine that the proper size breaker is at 50 A.
Which is thicker 8 gauge or 10 gauge wire?
The general rule of thumb is that the smaller the gauge number, the thicker the cable.
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,
Can I use 8-gauge wire on a 15 amp breaker?
You’re always allowed to use bigger wire
The circuit ampacity defines the minimum wire size needed. If you have larger wire on hand, go ahead and use it. For instance I often run single appliance circuits that demand a 15A breaker.
Can you junction box 8-gauge wire?
The ground wire size for AWG 8 is one gauge smaller than the insulated wires. Wrap the wire clockwise around a 10/32 green ground screw inside the junction box. Tighten the screw to hold the wire inside the box, creating a ground to the junction box.
