You’ll want 14/2 NM… The rule for converting between aluminum and copper wire gauges is that in order to carry a given amount of current, you need an aluminum wire two sizes larger than the copper wire you would have used.
Can you use copper and aluminum wire together?
Many people would advise against splicing copper and aluminum wires. That is because the combination of these wires is known to corrode quickly when there is any moisture present. For this reason, many electricians would recommend sticking to one type of wiring in your home and rewiring where necessary.
How do you extend aluminum wiring?
Quote from the video:
Quote from Youtube video: I want to talk to you real quickly about the two methods that is able to be used. One is these illumines. These are twists down method which has allows the copper. And aluminum to say separate.
How do you connect aluminum wire to copper?
Quote from the video:
Quote from Youtube video: So i got this is my neutral. This is my hot and this is my ground right here. So we have to use these marets here they're very specific merits they're called merit 63. And it's gonna be hard to read
Can 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.) Almost any text or handbook on corrosion will have galvanic series table.
Can you splice aluminum wire to copper?
Electricians have to use specially designed connectors to splice copper and aluminum together. These connectors include chemicals to fight the oxidation and corrosion that occurs when aluminum and copper are spliced together.
Is Pigtailing aluminum wiring safe?
CPSC staff considers pigtailing with a COPALUM con- nector to be a safe and permanent repair of the existing aluminum wiring. The repair should include every connection or splice involving aluminum wire in the home, in- cluding outlets, dimmers, switches, fixtures, appliances, and junction boxes.
What’s the problem with aluminum wiring?
The problem with aluminum wiring is that it expands and contracts at a high rate, which can lead to loose connections. Connections between aluminum and copper can also cause oxidation, resistance, heat, increased expansion… you get the picture. All of that can lead to a fire.
Can a copper wire and an aluminum wire of the same length have the same resistance?
Why? Copper has a lower resistivity than aluminum, so if length is the same, copper must have the smaller diameter.
What do you put on aluminum wire?
Conductor termination paste are for use on splice and termination connections of aluminum, copper-clad aluminum and copper conductors. The paste gets used to retard oxidation at the conductor/connector interface.
Can you use copper lugs on aluminum cable?
Combining aluminium and copper is problematic. High-quality Al/Cu compression cable lugs are perfect for coupling aluminium conductors with copper elements. A compound in the aluminium connecting material improves the contact properties.
What happens if you mix aluminum and copper?
Quote from the video:
Quote from Youtube video: Welcome back in today's video I'm going to see whether it's possible to mix these two rather dissimilar metals together so here I have a piece of copper. And right here I have a piece of an aluminum.
What metal is compatible with aluminum?
While many people worry that stainless steel fasteners, such as screws, bolts, nuts, or host of other options, won’t work with aluminum due to the risk of galvanic corrosion between the two very different metals, the truth is that stainless steel is the metal of choice for fasteners to secure your aluminum materials.

How many fires are caused by aluminum wiring?
Statistics on fires caused by aluminum wiring aren’t kept, but the possibility still frightens federal officials and consumer advocates. An estimated 40,000 electrical fires of all kinds occur in homes each year, causing about $2 billion in property damage and killing three people each day, the agency said.
Is aluminum wiring illegal?
Aluminum wiring is not illegal, but it is no longer up to code and new homes are now built with copper wiring. If you are thinking about buying or selling a home with aluminum wiring, you will be ok as long as you follow the instructions on how to deal with it. How much does it cost to rewire a house?
Is it OK to have aluminum wiring in your house?
The aluminum wiring installed in homes during the 1960s and 1970s is considered a serious fire hazard. Problems with installation, outlet connections, and the metal itself resulted in wiring that degrades and loosens over time. If your home has aluminum wiring, you should repair or replace it right away.
Is aluminum electrical wiring safe?
Aluminum will become defective faster than copper due to certain qualities inherent in the metal. Neglected connections in outlets, switches and light fixtures containing aluminum wiring become increasingly dangerous over time. Poor connections cause wiring to overheat, creating a potential fire hazard.
Do you need special receptacles for aluminum wiring?
Usually, receptacles approved for aluminum wiring will get stamped CO/ALR, CU-AL, or AL-CU, indicating they may get used for both copper and aluminum. More modern “decora” switches and outlets are not aluminum wire rated. Do not use outlets marked with AL and a line through it.
