Due to multiple revisions of the L86 dimmer module, there are many small differences between a
few cards. These differences may require you to have different tools to make your life easier.
Examples of this would be for the removal of some power cubes, there might be a 3/8"or a 5/16"
nut holding it in place. A normal nut driver will not fit in the power cube so you need to take the
circled portion of your nut driver to a grinder.
The tip of this 5/16th nut driver was ground down so that it could remove the shown nut. Without
grinding down the tool, you would not be able to fit it into the power cube.
On some older models of the L86 dimmer modules, instead of using joint compound, ETC used a
Sil Pad. When replacing the power cube, do not reuse this Sil Pad. Instead install the new power
cube with joint compound.
