1. A sprinkler resistant tap-off base comprising:a tap-off base molded from an electrically insulating material, said tap-off base having an overmolded perimeter seal molded over a perimeter flange extending from a front surface of said tap-off base, said overmolded seal being sufficiently pliable to provide a liquid resistant seat between said tap-off base and a busway electrical distribution system housing when said tap-off base is properly installed thereon; and a removable cover installed on said tap-off base such as to significantly overlap said overmolded perimeter seal. 2. The tap-off base of claim 1, wherein said tap-off base is attached to said housing by flexible retaining tabs, which engage an inside surface of said housing.3. The tap-off base of claim 1, wherein a color for said overmolded seal is selected to be highly visible from a significant distance and having a high contrast to the colors of said tap-off base, said busway housing and said cover, thereby allowing one to easily determine if said cover is in place from said significant distance.4. The tap-off base of claim 1, wherein a color for said cover is selected to be highly visible from a significant distance and having a high contrast to the colors of said tap-off base and said busway housing, thereby allowing one to easily determine if said cover is in place from said significant distance.5. A sprinkler resistant tap-off base comprising:a tap-off base molded from an electrically insulating material; and an overmolded perimeter seal providing a liquid resistant seal between said tap-off base and a busway electrical distribution system housing on which said tap-off base is installed and between said tap-off base and a tap-off unit cover installed on said tap-off base. 6. The tap-off base of claim 5, wherein said perimeter seal is molded over a perimeter flange extending outwardly from a front surface of said tap-off base.7. The tap-off base of claim 6, wherein said perimeter flange defines an upturned distal end, which provides a sealing surface for said tap-off unit.8. The tap-off base of claim 5, wherein said perimeter seal includes a sealing rib which provides said liquid resistant seal between said tap-off base and said busway housing.9. A sprinkler resistant tap-off base comprising:a tap-off base molded from an electrically insulating material and defining flexible retainers for securing said tap-off base to a busway electrical distribution system housing by engaging an inside surface of said housing; a seal providing a liquid resistant seal between said tap-off base and said housing; and a cover installed on said tap-off base such as to significantly overlap said seal such that a liquid resistant seal between said tap-off base and said cover is obtained. 10. The tap-off base of claim 9, wherein said seal is molded over a perimeter flange extending from a front surface of said tap-off base.11. The tap-off base of claim 10, wherein said seal significantly covers said perimeter flange.12. The tap-off base of claim 11, wherein said perimeter flange defines an upturned distal end, which provides a sealing surface for said cover.13. The tap-off base of claim 11, wherein said seal includes a sealing rib which provides said liquid resistant seal between said tap-off base and said busway housing.14. The tap-off base of claim 9, wherein a color for said seal is selected to be highly visible from a significant distance and having a high contrast to the colors of said tap-off base, said busway housing and said cover, thereby allowing one to easily determine if said cover is in place from said significant distance.15. The tap-off base of claim 9, wherein a color for said cover is selected to be highly visible from a significant distance and having a high contrast to the colors of said tap-off base and said busway housing, thereby allowing one to easily determine if said cover is in place from said significant distance.16. A sprinkler resistant tap-off base comprising:a tap-off base molded from an electrically insulating material and having a perimeter seal providing a liquid resistant seal between said tap-off base and a busway electrical distribution system housing on which said tap-off base is installed and between said tap-off base and a tap-off unit installed on said tap-off base. 17. The tap-off base of claim 16, wherein said perimeter seal is molded over a perimeter flange extending outwardly from a front surface of said tap-off base.18. The tap-off base of claim 17, wherein said perimeter flange defines an upturned distal end, which provides a sealing surface for a rear wall of said tap-off unit.19. The tap-off base of claim 16, wherein said perimeter seal includes a sealing rib which provides said liquid resistant seal between said tap-off base and said busway housing.
