Determine all the combinations of the following 120-volt kitchen appliances that can be operated simultaneously without tripping a 15-ampere circuit breaker: blender (300 W); clock radio (70 W); coffee maker (1200 W); food processor (200 W); microwave oven (1450 W); toaster oven (1150 W). Would you recommend having more than one 15-amp circuit to accommodate these appliances? Would you recommend a dedicated circuit for any of these appliances?
