An eighteen-unit multifamily dwelling contains the following appliances in each unit : a 1-kVA, 115-volt dishwasher, a 1/3 hp, 115-volt in-sink waste disposer and a 4500-watt, 230 volt water heater. Using the standard method, what is the service neutral load contribution, in volt-amperes , for these appliances ? ( Assume water heater watt rating equivalent to volt-ampere )

A computer's power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. You are building a new computer. You are deciding which type of power supply to install. Which of the following definitions BEST describes a valid type of power supply? Correct Answer: A single-rail power supply provides one rail (PCB trace). This provides the best safety for the computer by providing a single point of shutdown in the event of a short circuit. Correct Answer: A single-rail power supply provides one rail (PCB trace) used to always provide equal wattage to all devices attached to the power supply. Correct Answer: A dual-rail power supply provides separate rails (PCB traces) used to provide equal wattage to the devices attached to each rail. Correct Answer: A dual-rail power supply provides separate rails (PCB traces) used to balance the power load between multiple circuits, which prevents any one circuit from becoming overloaded.
