Can you use aluminum wire for a sub panel?
However, in larger-capacity circuits, such as a main service entrance for a house, or in a situation such as yours—a feeder from the main electrical panel to a subpanel—aluminum cable may still be permitted.
What size aluminum wire is good for 50 amps?
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.
Is aluminum wiring safe in a house?
The wiring itself isn’t a problem; aluminum conducts electricity safely. The U.S. Consumer Product Safety Commission (CPSC) reports that homes with aluminum wiring are 55 times more likely to have “fire hazard conditions” than homes wired with copper.
What size 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 minimum of 1.5 inches, schedule 40 or 80 PVC conduit for underground service.
How many amps is #4 wire good for?
How many amps can a 4 gauge wire handle? It has a rated ampacity of 85 amps at 75°C. This means that, for average use, the 4 gauge wire can handle up to 85 amps safely.

What do you do with aluminum wiring?
Over time, aluminum wiring tends to break down and degrade. Broken segments of wire are also a significant fire hazard. The only way to deal with the degradation of the wiring itself is to replace it entirely. Replacing aluminum wiring with copper wiring is the best way to prevent future wiring problems.
Should I use copper or aluminum wire?
Aluminum Wire vs Copper Wire For its ease of use and ability to effectively conduct electricity, copper is the best kind of wiring for your home. Copper wiring is more stable than aluminum and smaller conductors are needed to transmit power loads. Overall all it is more durable and performs better than aluminum wiring.
Can I use aluminum wire instead of copper?
Aluminum wire is generally easier to use than copper because it’s lighter and more malleable, making it an ideal wiring material to use over long distances. The downside to aluminum wiring is that it’s vulnerable to corrosion and therefore cannot match the lifespan of copper wire.
What size aluminum wire is good for 400 amps?
400 amp. 400 amp service requires an aluminum wire size of 1000 kcmil. In contrast, a copper 600 kcmil can handle that amount of power.
