4. Generously apply the NO-OX-ID compound (sufficient enough to
cover with a noticeable film) to both sides of the movable contact blades
and to the adjacent insides stationary contacts and the hinge.
5. Reinstall the arc hood that was removed in Step 3.
6. Reinstall the line guard cover that was removed in Step 2.
7. If the lubricated disconnect switch is housed in a plug-in unit, reinstall
the unit. (For installation of unit, refer to publication
2100-IN014x-EN-P, Installing Units with Vertical Operating Handles).
NOTE: If the unit requires lubrication because of corrosion (for example, a
sulfuric environment), replacing the unit disconnect may be required to avoid
overheating conditions. Lubrication may temporarily resolve overheating,
however replacing the disconnect switch would be the ideal, long-term
solution.
NOTE: For more information on disconnect switch temperature analysis,
please see Service and Repair Guidance for Motor Control Centers, publication
2100-TD028x-EN-P.
