preclude it as a potenal source of moisture collecon. However, whether installed with
or without conduit, all cables should be examined for nicks and cuts that compromise the
protecve outer jackeng. In parcular, mul-conductor cables can act as very eecve
wicks when the outer jacket has been cut or damaged. Once moisture ingresses into the
cable, it will oen nd its way into the switch via this wicking mechanism, even when an
appropriate gland seal is used at the switch’s conduit opening and the outer periphery of
the cable is not leaking at the gland.
2.11.3 Liberally Apply Silicone Dielectric Grease to all Openings
The primary points of moisture entry into the switch are where the housing is penetrated:
- The setpoint adjustment screw (5550 only)
- The reset plunger (5550 only)
- The conduit ng(s)
- The seal between housing body and housing cover
O-ring seals and gaskets are used at each of these entry points and silicone dielectric
grease is applied at the factory. However, in extremely moist environments an addional
liberal coang of silicone dielectric grease should be applied in the eld at me of
installaon. This pracce will provide added protecon against moisture ingression
over me. Metrix recommends Dow Corning #33 Molykote® Extreme Low Temperature
Silicone Grease or equivalent.
