for USA, Canada and countries using similar 60Hz mains suppliesUsing W=V*A, you can figure 120volts*15amps = 1800 watts. Typically you want to use around 80 percent of your capacity, so you are left with 1440 watts.

You'd have to check the listing on your fan, but assume it uses around 400 watts at the very most. Your light fixtures will depend on the wattage of bulb you are using, so figure you can run 10 100 watt light fixtures in addition to your fan.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

In Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

Recessed lighting is used to keep the ceiling aesthetically unbroken. When fixtures are fixed to the ceiling some architects to not like this as it distracts the viewer from the look of the room. By installing the fixtures in the ceiling, the view is of light emitting from the ceiling without seeing the lighting fixtures.
