#2 Copper. Scrap copper that has a dirty appearance falls under the #2 copper grade. To qualify for this category, the material's copper content should be 94 to 96 per cent. Any unalloyed wire or pipe that has solder, paint, coating and other types of tarnishing falls are classified as #2 copper.
What is the difference between 2 0 and 2 AWG?
2 AWG will handle around 94 Amps, while 2/0 AWG will handle around 190 Amps. For a 3% drop where the load is less than 20 feet from the battery and you are drawing 100 Amps, you would need 2/0.
What is number 2 wire used for?
USE-2 cable stands for Underground Service Entrance cable. USE-2 cable can be used underground since it is able withstand pressure and is resistant to other elements such as sunlight (black only), oil and gas.
What is se conductor?
The lettering “SE” on a cable indicates the cable outer jacket and the internal conductors are designed for above-ground installations and are listed for locations where the cable jacket and internal conductors are exposed to the sun in wet locations.
What is type SE wire?
Service Entrance (SE) cables are electrical cables that bring power from electrical companies to residential buildings and our homes. These electrical cables are rated 600 volts and are suitable for both dry and moist applications. Both SER and SEU are flame-retardant and resistant to moisture.3 Dec 2020
Where is SE permitted?
Type SE service-entrance cable shall be permitted for use where the insulated conductors are used for circuit wiring and the uninsulated conductor is used only for equipment grounding purposes.
What is a single insulated conductor?
[′in·sə‚lād·əd kən′dək·tər] (electricity) A conductor surrounded by insulation to prevent current leakage or short circuits.
Is Ser rated for underground?
SE cables simply can't be buried, conduit or no conduit.5 Oct 2020

What is the best type of copper wire?
Beryllium Copper Wire has the advantage of copper's high strength combined with non-magnetic and non-sparking qualities. This copper alloy wire can be age- or mill-hardened.
What are the types of copper cables?
Copper cable uses electrical signals to pass data between networks. There are three types of copper cable: coaxial, unshielded twisted pair and shielded twisted pair. Unshielded twisted pair is made by twisting the copper cables around each other and this reduces degeneration.
What type of copper is used in electrical wiring?
The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C11040). This copper is at least 99.90% pure and has an electrical conductivity of at least 101% IACS.
