Is it code to tap into a main 100 amp breaker to create a subbreaker for a/c unit?

need to know if it is code to tap 100 amp beaker to create a sub-breaker for the a/c unit? also a double tap is not allowed on breakers but is it ok to tap a very low voltage such as a doorbell on the breaker which might appear to be doublle tap?

Is it code to tap into a main 100 amp breaker to create a subbreaker for a/c unit?
refer to Article 240.21 of the National Electrical Code...us old timers refer to it as the "10 foot tap rule"
Reply:it is OK as long you do not above the capacity (100amp) load
Reply:USA I am not sure what you mean by tap 100 amp breaker. If you mean can you place another set of wires on the lugs of the breaker, NO. You will need to create more space in your existing breaker box, or replace it, or add a new sub-panel. Also, do not mix low-voltage with 120 or 240 volts at a breaker.





Since you had to ask the question, I am assuming you are not familiar with electrical work. Please hire a licensed electrician to take care of this for you. Tapping off a main line is not something for the untrained to do.
