1) The local power company should be consulted

  • 1 hp = 0.746 kW
  • 1 ft (foot) = 0.3048 m

If undersized wire is used between the motor and the power source, the starting and load carrying cap abilities of the motor will be limited.

Apparent Power is the power supplied to the electric circuit - typical from a power supplier to the grid - to cover the real and reactive power consumption in the loads
