For a 150 amp service entrance cable, you would typically use 2/0 AWG (American Wire Gauge) copper or 4/0 AWG aluminum cable. This size provides the necessary capacity to handle the electrical load of a 150 amp service. It's recommended to consult with a licensed electrician for specific guidance based on your local electrical code requirements.
To calculate voltage drop to size the wire, a voltage must be stated.
For a 250 amp load, a cable size of at least 3/0 AWG (American Wire Gauge) or 70mm^2 is recommended. For a 160 amp load, a cable size of at least 1/0 AWG (American Wire Gauge) or 50mm^2 is recommended. It is important to consult local electrical codes and regulations to ensure compliance.

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.
The wire size in a meter stack is governed by the size of the first over current device.
