What size aluminum wire is rated for 50 amps?
No. 4 AWG
50 amp Aluminum Wire Aluminum wires are ranked in a different way than copper wires are. For a 50 amp aluminum wire, you should use the No. 4 AWG. The smaller sized the number on the wire is, the larger the wire size.
What size aluminum wire do I need for 100 amp service?
#2
A 100 amp sub panel wiring size requirement is #4 for copper wires and #2 for aluminum wires.
How many amps will number 6 aluminum wire carry?

What is the amperage rating?
Ampere rating is an electrical current value given to every fuse. This value is the allowable current which can flow continuously through the fuse under specified conditions. This value can also be referred to as current-carrying capacity or ampacity.
What size wire do I need to run 50 amps 100 feet?
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 is the ampacity of #2 Aluminum?
What size aluminum wire do I need for 60 amps?
In order to use 60 amps, a 6 gauge wire is required. But, if you plan on running the wire over long distances then the most suitable wire to use would be one of 4 AWG.
What size aluminum wire is good for 200 amps?
Installation of 200 amp electrical service needs a #2/0 AWG copper wire or #4/0 AWG for aluminum or copper-clad wire inside a 3″ conduit. Wiring a 200 amp electrical service is not a DIY job. It often requires a permit and professional installation by a qualified electrician following local electrical codes.
What is the ampere rating of a condconductor?
conductor does not have to be type TW, it could have a higher temperature designation such as THW or THHN; however, the ampacity must be based upon a 60°C rated conductor. Notice that a No. 6 aluminum type THHN conductor has an ampacity rating of 60 amperes which is higher than the 55 ampere rating for No. 6 copper TW.
What are the temperature ratings for insulated conductors?
The tables below are intended to be a general guide for wire size and amp ratings. Ampacities of insulated conductors Wire Size 60°C (140°F) 75°C (167°F) 75°C (167°F) 75°C (167°F) AWG (mm²) Copper Aluminum Copper 14 (2.1) 15 – 15 12 (3.3) 20 15 20 10 (5.3) 30 25 30

What is the ampacity of a conductor?
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
