What is the amperage for this circuit?

Because you have a ceiling fan installed you may already be pushing the max limit of the circuit amperage, particularly if the circuit is 15 amps.

While there is no restriction on the number of outlets (lighting or receptacle) in a residence, there is a common sense number, usually between 10 or 12, depending on the circuit load being serviced. You already have 14.
