Possible Signs of Inadequate Electrical Systems

  • Larger fuse sizes used to "prevent fuses from blowing." Note: It is probable that 30 amp fuses or larger are the proper size for the water heater, dryer and stove, but not for other circuits.
  • 15 or 20 amp fuses blow regularly.
  • Extension cords used as a permanent part of the system.
  • Lights dim when an electric appliance is turned on.
  • Use of adapters to increase the number of appliances plugged into one receptacle.
  • Use of converter plugs to allow appliances with three-pronged plugs to be plugged into two-pronged receptacles.
  • Three or more electrical panels in a single family home.
  • Messy wiring practices.
