How to Replace 3 Lamp Series-Parallel Ballast with Parallel Page 2

There are two more options for rewiring these lampholders for parallel ballasts.

  1. Replace all of the non-shunted lampholders with shunted. Wire the new ballast as parallel connecting the new ballast wires directly to the new shunted lampholders (option 2).
  2. Remove all of the existing non-shunted lampholders from the fixture and remove all of the wires from each of these lampholders (option 3). Reinstall lampholders after they are rewired.
