    (b) Connected load. The connected load on a lighting branch circuit 
must not be more than 80 percent of the rating of the overcurrent

accordance with IEEE Std 45, section 21.6.
    (c) Lighting fixtures on lighting circuits. Each lighting fixture 
must be on a lighting branch circuit.
    (d) Overcurrent protection. Each lighting branch circuit must be
