In copper 1 AWG. In aluminium 2/0 (pronounced 2 ought). This is for a typical service entrance wire in a residential application.

What size Aluminum wire is used for ground in breaker box?

For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.


What size aluminum wire for 100 amps undergroundservice 60 feet from meter?

A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.


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.


What is largest wire you can use in 150 amp breaker panel?

A 1/0 copper conductor with an insulation factor of 75 and 90 degrees C is rated at 150 and 155 amps respectively. Any size larger that 1/0 can be used but no conductor smaller that 1/0 will be approved for connection.

What size wire do i need to feed a single phase V primary and a V secondary fed from a 150 amp circuit breaker?

Information is incomplete. You need to know the load in Watt or Kilowatt and the voltage on the secondary side to determine the load current, on which the size of the wire is designed.

An exact breaker size can not be given because the voltage, and hence the calculation for current, is not given. A transformer shall be protected by an over current device that is not rated at more that 150% of the primary current.
