Best Answer

There should be a rating panel on the fan. Let's say it says 2A. You should not load the circuit any more than 80% of breaker rating. In our example 80% of 20 A is 16 A so you could handle 8 fans if they were 2 A each. However, the starting current of motors is higher than running current. Depending on speed setting of fans and if they are all started at the same time, the number may be less than 80% of load. Find the rating of your fans and do the calculations.

You have to add up the amps required by each fan and when you get to 12 amps, you have your answer.

You need to look at the rating on the fans to see how much current they draw including lighting. Add up the currents and stay below 16 amps for the 20 amp breaker and below 12 amps for the 15 amp breaker. If all fans were to start at the same time the excess starting currents could trip the breaker.

Yes

To meet the requirements of the electrical code you have to know the total wattage of the lights that you are going to connect to the 15 amp circuit.

Use 15 amp breaker with 14 gage wire or 20 amp breaker with 12 gage wire. Either way will work just fine.

No, the six outlets are not amperage rated to be connected to a 20 amp circuit. A normal 15 amp receptacle can not be protected by a 20 amp breaker. Change the 20 amp breaker to a 15 amp breaker. This combination will pass code regulations. =============== In the United States, in a home, you can connect two hard-wired (not cord and plug connected) fans and six receptacles (outlets) to a single 20 amp circuit provided the 2 fans do not draw more than 10 amps together. If they are cord and plug connected, this limitation on the fans does not apply. In commercial and industrial installations, power to hard-wired equipment is provided on different circuits than receptacles.

A 30 amp breaker is usually used for a dedicated 30 amp device. Ordinary 15 amp receptacles can not be connected to a breaker of higher trip capacity than the rating of the receptacle. The wire size for a 30 amp breaker is #10 AWG.

No, it is a 30 amp breaker on each side. Remove it and install a 15 amp single pole breaker.

Replace the 30 Amp Breaker with a 15 Amp breaker.
