    That varies with load and ambient temp. Especially with a cap tube system. Fully loaded the high side will be about 15 to 20 degrees over ambient. By using a thermometer, vapor/pressure chart, and ammeter you can come close. But you have to make sure the condenser is clean and has adequate air flow.
