ABSTRACT:
A moisture drain plug for use with a cylindrical motor housing provides a plurality of diverse drainage pathways to promote the egress of moisture from within the housing. The plurality of diverse drainage pathways includes a first set of primary moisture egress pathways and a second set of secondary moisture egress pathways. Should one or more of the primary moisture egress pathways become clogged, the secondary moisture egress pathways provide for more than adequate drainage from the motor housing.
