TYPICAL KITCHEN APPLIANCE BRANCH CIRCUITS
Receptacle outlets are required at each counter space wider than 12 in. spaced so that no point along the wall line is more than 24 in. from a receptacle. Island and peninsular type counter tops are required to have one receptacle for each 4 feet of counter-top. Counter-top outlets are required to be Ground Fault Circuit Interrupted (GFCI) protected. Outlets in the kitchen are required to be divided between two 20 amp. circuits.
Primary task lighting in the kitchen must be fluorescent, however; secondary task lighting may be incandescent.
Type of Appliance | Branch Circuit Rating | Electrical range (240V) | 50 amperes | Kitchen counter top small appliance branch circuit (120V) | 20 amperes | Counter-mounted electric cooking unit (240V) | 30 amperes | |
