- NEMA 3R Sentron busway must be limited to 50 ft installation to limit outdoor exposure. By doing this you are limiting the amount of busway, specifically number of joint,s allowed per outdoor run.
- The external enclosure has drain holes to limit accumulation of water on the exterior housing. It also includes orientation specific weep holes at the joints that prevent accumulation of condensation in the joint cavity. The addition of a rain shield is a recommendation.
