Can a 100 amp breaker handle 5 air conditioners?

Answer 1

That depends more on the current usage of each a/c unit than it does on the number of a/c units.

Check the current draw of each should be listed somewhere on the units. Add up the current draw, and don't exceed 80% of the rating of the breaker.

Answer 2

No, a 100 amp breaker is not sufficient to handle 5 air conditioners. Each air conditioner typically requires its own dedicated circuit with an appropriately sized breaker based on the unit's electrical requirements. You would need multiple circuits and breakers to safely power 5 air conditioners.
