Background Information

Does Sharon and Stanley need some 240 V lines as well as 120 V ? Sharon and Stanley need both the 120 volt and 240 volt wiring in their household. Some examples of 240 volt appliances are air conditioning unit, clothes dryer, and water heater, but in our project we are only going to be dealing with the range(oven/stove). It is the only appliance that we are going to wire that uses 240 volt.

What voltage are the electrical lines coming into the house?The voltage of the electrical lines coming into the house is 120 volt per hot wire. To produce 240 volt needed for certain appliances, we use a dipole switch breaker in the breaker box that allows 2-120 volt wires to combine that produce 240 volt.

How are the ratings on the circuit breakers determined? A circuit breaker is rated by the voltage and the current. The ratings on the circuit breakers signify the total load capacity of wattage that the circuit breakers can handle without breaking. They are designed to carry 100% of their rated current but as a safety measure, The National Electrical Code (NEC) determined that the safety capacity should only be 80% of that rated load capacity of wattage.

How are houses wired? All the wiring in the house is done in parallel because in series, the voltage splits between the different types of small-appliances running in a closed circuit.

Is there a minimum number of outlets that must be wired for each room?There is no minimum or maximum number of receptacles requirement by the NEC but there are specific rules for their placement such as: include receptacles on all walls 24 inches wide or greater, include receptacles so a 6-ft. cord can be plugged in from any point along a wall or every 12-ft. along a wall or more, and include a switch-controlled receptacle in rooms without a built-in light fixture operated by a wall switch.

How are overhead light switches wired into the circuit? An overhead light is wired in parallel with the rest of the circuit running in the wall, but its switch is wired in series with it. It is placed on the hot wire before it connects back to the overhead light and after it leaves the main circuit.

What questions should you ask Sharon and Stan in order to determine their wiring needs?To be able to wire the house for Sharon and Stan we need to ask them about the different types and location of appliances they will be using (120 or 240 volt), and their simultaneous uses.
