Final answer:
The outdoor receptacle requirements for a one-family dwelling include the installation of at least one 125-volt, 15- or 20-ampere receptacle accessible on the exterior of the dwelling. If a 100 A house is operating at 80% of its rated capacity, it consumes 9.6 kW of power. If sustained for a month, the consumption would result in a bill of $1.44 at $0.15/kWh.
Step-by-step explanation:
The outdoor receptacle requirements for a one-family dwelling as specified in NEC 210.52(E)(1) state that at least one 125-volt, 15- or 20-ampere receptacle must be installed on the exterior of the dwelling. This receptacle should be readily accessible and located no more than six feet, six inches above the finished ground level.
For example, if a 100 A house is operating at 80% of its rated capacity, it is consuming 80 A of current. To calculate the power consumed, we multiply the current by the voltage (120 V) to get 9600 watts or 9.6 kW. If this power is sustained for a month, it would result in a consumption of 9.6 kWh on the bill. At a cost of $0.15/kWh, the total cost would be $1.44.
