Aluminum wire size chart

Aluminum AWG wires (1st Chart): 4/0 AWG, 3/0 AWG, 2/0 AWG, 1/0 AWG, 1 AWG, 2 AWG, 3 AWG, 4 AWG, 5 AWG, 6 AWG, 8 AWG, 10 AWG, and 12 AWG. These are considered smaller wires with the highest median ampacity of 180A.

What size aluminum 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.

How many amps will 2 0 aluminum wire carry?

Conductor Size (AWG/KCMIL)	60°C (140°F) TW, UF	75°C (167°F) RHW, THHW, THW, THWN, XHHW, USE, ZW
1/0	100	120
2/0	115	135
3/0	130	155
4/0	150	180

What size aluminum wire will carry 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.

What diameter is #2 aluminum wire?

Conductor Diameter Inches: 0.268. Insulation Thickness Inches: 0.045. Jacket Thickness Inches: 0.006. O.D.

What is #2 aluminum wire?

#2 Stranded Aluminum XHHW-2 Wire XHHW-2 are primarily used in air duct, conduit or recognized raceways for services, feeders and branch circuit wiring as specified in the National Electrical Code. Applicable Standards: UL 44.

Is #2 aluminum good for 100 amp service?

Also, you can only use the #2AL at 100-amps feeding the service disconnect for the residence. Any feeder after that needs to go by 310.15(B)16 (which has #2AL limited to 90A at 75c), if the sub panel carries 100% of the dwelling load, the feeder will not be required to be larger than the service conductors.

Can you use number 2 aluminum for 100 amp service?

As a general rule # 2 awg aluminum wire is used for 100 amp service entrances.

What size wire do I need for 200 amp service 150 feet?

The 250 KCMIL wire is the perfect size wire for 200 amp service because it has 255A ampacity (a minimum of 250A ampacity requirement is satisfied).

What size wire do I need to run 50 amps 100 feet?

In most cases, 6 AWG is an almost perfectly-sized wire for a 50 amp breaker. In limited cases, you will probably have to use a larger 4 AWG wire. That's when you have a long circuit and are sending electrical current at some distance (100 feet or more).

How far can I run #2 aluminum wire?

Example calcuation 2 - Aluminum Wire, 1 phase power Cable run: 400 ft.

Will a 100 amp breaker accept 2 0 wire?

If you consult the wire gauge chart, you see that the #0 wire can handle 150 amps. It's too small. 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 to run 50 amps 200 feet?

Calculating With Voltage Drop Considered On the off-chance that your panels are rated at 110V/120V, the right wire size for 50 amp sub panel should be bumped up to 2 AWG copper or 1/0 AWG aluminum for 200 ft.

Can 8 gauge wire handle 50 amps?

8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable.

What size wire do I need to run 60 amps 100 feet?

The rule of thumb for voltage loss dictates that if the length of the 60 amp wire is 100 feet, we will see a 20% voltage drop. That means that 4 AWG wire will not suffice; we might have to use 3 AWG wire for a 60 amp breaker at a 100+ feet distance.

What size wire is bigger 2 0 or 4 0?

As the AWG value becomes larger, the electrical wire becomes thinner. The sizes of wires larger than 0AWG are indicated as 2/0, 3/0, 4/0, … and, for example, the size 3/0 denotes the size 000.

What is bigger 2 0 or 2 AWG?

More specifically, a wire labeled 2 0 will be thicker than a wire labeled 2 AWG. Also, lower AWG wires typically have higher amps, which is an electrical current's base unit. For example, a 2 0 copper wire will have up to 200 amps while a 2 AWG copper wire will have up to 125 amps.

What size wire is bigger 1 0 or 2 0?

The more the number of zeros indicating a cable's American Wire Gauge measurement, the bigger the cable. So, it is accurate to conclude that a 2/0 is bigger than a 1/0.
