amps needed

        Hi,

        I am currently working on finishing my basement.  I have installed
        a 1/2 bath and a sewage pump for upflush purposes.  My question
        is want amperage line/breaker should I use for the sewage pump,  the
        instructions did not say.  The rated amperage on the label is 12.
        I was thinking of putting it on a 15amp circuit which has 3 60W lights.
        If my math is correct, this would be 13.5amps.  I was wandering
        if it should be on a 20amp line.
