Copper to aluminum wire size chart

A commonly used rule-of-thumb for converting the two conductor metals is to have aluminum two AWG sizes larger than copper for equivalency. This works in most cases when one is working inside the American Wire Gage system.

How do you calculate copper and Aluminium wire size?

The online electrical calculator allows you to measure the scale of an electrical circuit's copper, aluminum wires.
Wire Circular Mils = 2 x Specific Resistance x Amperes x Distance / (Voltage Drop / Source Voltage)

Can you connect copper wire to aluminum?

Can You Connect Copper Wire to Aluminum Wire? Incorrect repairs to aluminum wiring, such as connecting aluminum wire to copper wire with copper twist-on wire connectors, can make the problem even worse and can be dangerous.

Is aluminum wire larger than copper?

Disadvantages of aluminum wiring: Aluminum conductors are going to be larger than that of a comparable copper conductor.

What size aluminum wire is good for 60 amps?

60 amp wire size is either 6 AWG or 4 AWG wire (AWG stands for American Wire Gauge; standard wire sizing is the US) for 220V voltage. An amateur will use a 6 AWG wire size for 60 amp 220V. A professional will always use 4 AWG wire size for 60 amp 220V.

What size wire is good for 200 amps?

The Short Answer: For a 200 amp service, you'll need a #4/0 aluminum wire.

How do I calculate what size wire I need?

How do you determine cable wire size? Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4.

How far can you run 10-gauge wire for 30 amps?

You must also consider the wire length for your 30-amp circuit, in addition to the wire AWG. A maximum length of 150 feet is allowed when using a 10-gauge wire size.

How do I choose a wire size?

To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.

How do you join copper and aluminium?

And is free-flowing this alloy is preferred for joining single copper to aluminum transition joints

What happens when copper and aluminum touch?

A. Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.)

What happens when you mix aluminum and copper wire?

The problem is particularly prevalent when copper and aluminum wires are connected because of the chemical reaction that occurs between the two metals. If not properly connected, oxidation and corrosion occur.

What are the disadvantages of aluminum wiring?

The downside to aluminum wiring is that it's vulnerable to corrosion and therefore cannot match the lifespan of copper wire. Likewise, its softness makes it prone to breakage and loose connections.

Can I use aluminum wire to feed a subpanel?

Safety concerns caused aluminum wire to be banned from use in branch circuits years ago, but it is a common option for feeding main service panels and subpanels.

What is the difference between 2 0 and 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 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).

Can 8 gauge wire handle 60 amps?

RULES OF THUMB “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

What wire size do I need to go 100 feet for a 100 amp service to a workshop?

If you check the wire size chart (you have the link in the introduction), the #0 AWG wire (also known as 1/0 AWG wire) has 150 ampacity. That means that #0 AWG wire is the perfect size wire for 100 amp service 100 feet away.
