An air conditioning system charged with R-410A is operating with a suction pressure of 130 psig which equates to a 45F saturation temperature. If the manufacturer calls for a 15F superheat, what should the suction line temperature be?
 
  A) 45F + 15F = 60F suction line temperature B) 45F - 15F = 30F suction line temperature
  C) 130 psig + 15F = 190F suction line temperature D) 130 psig - 15F = 115F suction line temperature

Question 2

  A) Larger gauge wire than the run winding.
  B) The same gauge wire than the run winding.
  C) Higher flux density, random molecular alignment wire.
