    Default how many lights in a circuit as per code

    It is my intention to place 24 pot lights around

    the perimeter of the house.

    24 lights of 50 watts, having of total of 1200

    watts.

    1200 watts divided by 120 volts gives me 10 amps.

    I have placed a new breaker of 15 amps. Wich lead

    me to think that I will be OK.

    The question that I have is: How many lights I am

    allowed asper code in one circuit.

    IT is 12 lights ONLY????

    PLEASE REPLY..thanks

    It would really make no sense to have a limitation on the number of luminaires on a circuit, in the absence of
    any information on the power consumed per fixture. I have never encountered such a code limitation, and doubt
    that any such exists.

    To calculate your total fixture wattage, you need to go by the mfg's max bulb wattage for that fixture. (i.e. I you are using 50watt bulbs but the fixture is rated for using 75 watt bulbs you need to use the 75watt figure to calculate with.) That said, I always try to stay within 80% or less of the circuit rating.(appox 1440 watts for a 15amp circuit)

    As I have read on other forums about the CEC, 12 is the max.
