A cable with two insulated 4 AWG wires and an uninsulated grounding wire in a common sheath (which is what makes them a cable.) You might need a real electrical supplier, rather than Homely’s Despot to find that. It’s a bit out of their usual range of product. Follow this answer to receive notifications.
What AWG is ground wire?
6 AWG
Ground wires for residences typically are made of copper and are #6 (6 AWG) or larger. for 200 Amp services, a #4 grounding electrode conductor (ground wire) is required.
What does it mean when a wire is ground?
Grounding wires serve as an alternate path for the current to flow back to the source, rather than go through anyone touching a dangerous appliance or electrical box. Confusion arises because it is commonly referred to as a ground wire even though it is more correctly called a “grounding” wire.
What does 4 AWG wire mean?
Wire gauges range from low numbers to high numbers, with smaller numbers referring to smaller diameters and larger numbers representing larger diameters. For example, AWG 4 is 0.2043 inches in diameter, and AWG 40 is .
How many amps can 4 AWG handle?
4 Gauge Wire Details: Amps, mm, mm2, 4 AWG Wire Suggestion
4 gauge wire cross-section is 21.2 mm2. With such a cross-section and 4.89 turns of wire per inch, this kind of wire can handle quite a lot of amps. It has a rated ampacity of 85 amps at 75°C.
What is the best wire for grounding?
Bare copper
Bare copper is the most commonly used type of copper wire and is often referred to with the general term “grounding wire.” It does not have any sort of protective coating, however, the lack of insulation allows bare copper to have the best conductive properties.
What size ground do I need?
Table 250.122 Minimum Size Equipment Grounding Conductors for Grounding Raceway and Equipment
| Rating or Setting of Automatic Overcurrent Device in Circuit Ahead of Equipment, Conduit, etc., Not Exceeding (Amperes) | Size (AWG or kcmil) | |
|---|---|---|
| Copper | Aluminum or Copper-Clad Aluminum* | |
| 20 | 12 | 10 |
| 60 | 10 | 8 |
| 100 | 8 | 6 |
Does a ground wire carry current?
Ground wire acts as defense against unstable electrical currents. Under normal circuit conditions, ground wire isn’t carrying any current. But when an electrical accident such as a short circuit occurs, the ground wire takes the unstable current away from your electrical system and sends it toward the ground.
Is ground wire necessary?
The ground wire is not strictly necessary for the operation of a device, but it is still an important feature. This wire is designed to provide a path for electrical current to travel if the normal paths aren’t available. This could be because the other paths are damaged, or there is too much electricity for them.
What happens if you don’t ground a wire?
Don’t ground to the electrical box. Connecting the ground wire to a metal electrical box will energize the box in the event of a short circuit. The box could overheat and start a fire, or someone could get a shock from touching it.
What size ground do I need for a 100 amp service?
#8 AWG
| GROUNDING ELECTRODE CONDUCTOR SIZING (Table 250.66) | ||
|---|---|---|
| Size of Main Panel | Copper Conductors | Aluminum or Copper-Clad Aluminum |

| 125 Amps | #8 AWG | #6 AWG |
| 150 Amps | #6 AWG | #4 AWG |
What size ground do I need for a 200 amp service?
The minimum size equipment grounding conductor for this 200-ampere feeder is a 4 AWG copper conductor.
What is #4 wire rated for?
Table 310.15(B)(17)
| Size | Temperature Rating of Copper Conductor | |
|---|---|---|
| (AWG or kcmil) | 60°C (140°F) | 75°C (167°F) |

What does AWG stand for?
American Wire Gauge
American Wire Gauge (AWG) is the standard way to denote wire size in North America. In AWG, the larger the number, the smaller the wire diameter and thickness. The largest standard size is 0000 AWG, and 40 AWG is the smallest standard size.
What size wire is good for 100 amps?
For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire. Make sure to limit your voltage drop to 3% regardless of distance.
What size wire is needed for 50 amps?
6
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 you feed a 100 amp sub panel with a 50 amp breaker?
Just wire it up. There is no problem using a sub panel that can take more current than you will ever feed it. Points to note: The cable to your hot tub will be rated for 50A (not 100A); therefore you must not upgrade the breaker in your main panel to 100A.
How many receptacles can be on a 20 amp circuit?
The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.
What size wire do I need to run 100 amp Service 150 feet?
#00 AWG wire
Wire Size For 100 Amp Sub Panel 150 Feet Away
100 amp service 150 feet away from the sub panel requires #00 AWG wire (also known as 2/0 AWG wire). This wire has a median ampacity of 175 amps; more than enough than the required minimum 162.5 ampacity.
What size wire do I need for a 100 amp underground 100 ft run?
For a 100 ampere circuit, the conductors will likely be required to be 3 AWG copper or 1 AWG aluminum.
What wire do you use for a 200 amp service?
What Size Ground Wire for 200 Amp Service. The NEC is the electric code used in the United States. The minimum size for a grounding wire for 200 amp is #4 AWG copper or #2 AWG aluminum, according to Article 250 of the 2020 NEC.
