Weatherproof outdoor connections with waterproof butyl tape, as shown in the following photos:


Note:  The illustrations in this appendix depict Enclosure A; however, weatherproofing also should be applied to Enclosure B units.

  1. The following photo depicts the connector before weatherproofing. You will add three layers of tape; one 6-inch strip of butyl tape and two 6-inch strips of electrician’s tape are required.

  2. First, wrap the connector using the first strip of electrician’s tape, as shown in photos 2, 3, and 4. This serves as a base for the butyl tape, letting you remove the butyl tape easily when necessary.

  3. Next, in the same manner, apply a layer of butyl tape over the electrician’s tape, as shown in photos 5 through 8.

  4. Finally, apply a layer of black electrician’s tape over the butyl tape for further protection, as shown in photos 9 and 10; the butyl tape alone is not UV protected.
