What conductors are used for underground 200 amp service?
An underground 200 amp service has a couple of different options, depending on what type of wire you plan on running. You can choose between copper conductors and aluminum conductors. Copper is the most common conductor for wiring. It works so well because it has less resistivity than other metals.
Why is copper wire so good?
It works so well because it has less resistivity than other metals. Copper also oxidates less and does not rust. It does produce a green patina, but in the case of copper, it helps protect the metal from further erosion. For copper wiring with a 200 amp service, you will need to use #4 AWG copper wire.
How long has copper wire been used?
