  1. Determine the correct size generator.
    1. Use the following procedure to determine the correct size generator:
      1. List system components that use peak load requirements in watts.
      2. Add the wattage required by the system components.
      3. Perform the following equation: Total watts x 1.25 = kVA (kilovolt-amperes).
      4. Select a generator size that is equal to or greater than the determined kVA.
  2. Connect Power*
    1. Turn the main power switch off.
    2. Open electrical enclosure door. Terminal jumpers are located inside the electrical enclosure door.**
