What size service cable do I need for a 200 amp service?

Wire Sizes For 200 Amp Service Wiring 200 amp service requires either #2/0 copper wiring or #4/0 aluminum or aluminum clad wiring. Which wire used is determined by the voltage drop and length of the wiring. Many electrical contractors opt to use #4/0 aluminum or copper-clad wire.

Why copper is used for the wiring around a house but Aluminium is used for high voltage transmission lines?

Additional aluminium reduces power losses in the line by 25-40\%. Existing copper conductors are being replaced around the world, with companies tending to use aluminium wires when new power lines are constructed, especially in the low-voltage lines sector.

Can aluminum wire be used as a ground?
