  ## What is the service demand load for the clothes dryers?
  
  Clothes dryer. Per 220.18, the feeder or service demand load for electric clothes dryers in a dwelling unit shall not be less than 5,000W. However, if the nameplate rating exceeds 5,000W, use that rating as the load.
  
  ## What is the demand factor for space heating?
  
  It shall be permissible to apply a demand factor of 75 percent to the nameplate rating load of four or more appliances fastened in place, other than electric ranges, clothes dryers, space-heating equipment, or air-conditioning equipment, that are served by the same feeder or service in a one-family, two-family, or …
  
  ## How do you calculate the demand factor of a receptacle?
  
  Count the number of receptacles that will serve continuous-operation loads, and multiply that number by 125% for your new total. Then, count the number of receptacles that will serve noncontinuous-operation loads and add this to the previous total. Multiply the results of that addition by 180VA to get your answer.
  
  ## How do you calculate residential electrical load?
  
  1. Add together the wattage capacity of all general lighting branch circuits.
  2. Add in the wattage rating of all plug-in outlet circuits.
  3. Add in the wattage rating of all permanent appliances (ranges, dryers, water heaters, etc.)
  4. Subtract 10,000.
  5. Multiply this number by . …
  
  ## What is the demand factor for 6 dryers?
  
  The load for household electric clothes dryers in a dwelling unit(s) shall be either 5000 watts (volt-amperes) or the nameplate rating, whichever is larger, for each dryer served.

  ## What is meant by demand factor?
  
  Definition of demand factor
  
  : the ratio of the maximum demand during an assigned period upon an electric-power system to the load actually connected during that time expressed usually in per cent.
  
  ## What is the maximum demand for a 14kW electric range?
  
  The service demand load for one 14kW range is 8.8kW (See Figure 1). Regardless of the number, the first note applies if all the ranges are rated the same and are more than 12kW.
  
  ## How do you calculate electrical load demand?
  
  To calculate your load factor take the total electricity (KWh) used in the billing period and divide it by the peak demand (KW), then divide by the number of days in the billing cycle, then divide by 24 hours in a day. The result is a ratio between zero and one.

  ## What is the demand factor allowed by the NEC for calculating the neutral conductor size for an electric range load?
  
  The minimum size required for the neutral conductor is 4 AWG (see Figure 2). When calculating the feeder or service neutral load, it is permissible to apply a demand factor of 70 percent to household electric ranges, wall-mounted ovens, counter-mounted cooking units and electric dryers.
  
  ## How many luminaires do I need calculator?
  
  Calculation in 8 steps
  
  1. Total wattage of fixtures: Total wattage of fixtures = Number of lamps x each lamp’s watt. Total wattage of fixtures = 2 × 32 = 64 Watt.
  2. Lumen per fixtures. Lumen per fixtures = Lumen efficiency (Lumen per Watt) x each fixture’s watt. Lumen per fixtures = 85 x 64 = 5440 Lumen.
  3. Number of fixtures.
  
  ## How do you find power factor?
  
  The power factor of an AC circuit is defined as the ratio of the real power (W) consumed by a circuit to the apparent power (VA) consumed by the same circuit. This therefore gives us: Power Factor = Real Power/Apparent Power, or p.f. = W/VA.
  
  ## How do you calculate maximum demand for a house?
  
  Maximum demand is the load after applying diversity, for example: Total Connected Load x Diversity = Maximum Demand.
  
  ## What is the power factor?
  
  Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). … It is found by multiplying (kVA = V x A). The result is expressed as kVA units. PF expresses the ratio of true power used in a circuit to the apparent power delivered to the circuit.
