What size USE wire is needed for 200 amps?

As a service entrance wire you need AWG # 3/0 gauge copper.


What could be wrong if your home air conditioning unit is always cut off electricity?

sounds like you have a 100 amp service to your home.. that will need to be upgraded to a 200 amp service.. you shouldn't have any problems after upgrade..


Do you need to change the wire size going from 100 amp service to 150 amp service?

Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
