An environmentally robust joint for use in a lowering pole assembly comprising a lower pole section and an upper pole section. The joint includes a lower adaptor comprising a lower pivot member defining a first central wiring passage and an upper adaptor comprising an upper pivot member defining a second central wiring passage communicating with the first central wiring passage. The upper pivot member is rotationally coupled to the lower pivot member, and sharing a common axis of rotation. At least one of the lower adaptor and the upper adaptor comprises a pole adaptor mounted at an operative angle to the axis of rotation. The pole adaptor includes an open end for receiving an end of a pole section, and an internal wiring tube communicating with the first central wiring passage and the second central wiring passage.

1. A joint for use in a lowering pole assembly, the lowering pole assembly including: a lower pole section having an uppermost edge; andan upper pole section having an internal surface, the upper pole section being moveable relative to the lower pole section, the joint including: a lower portion defining a first central wiring passage which is fixed relative to the lower pole section;an upper portion defining a second central wiring passage which is fixed relative to the upper pole section, the second central wiring passage communicating with the first central wiring passage; andan internal wiring tube communicating with the first central wiring passage and the second central wiring passage, the internal wiring tube extending inside the upper pole section, the internal wiring tube having an upper end located above the uppermost edge of the lower pole section, the internal wiring tube being parallel to and spaced from the internal surface of the upper pole section, the internal wiring tube having an overlap portion with the upper pole section such that the upper end of the internal wiring tube is located higher than a lower end of the upper pole section, the overlap portion providing a water flow resistance between the upper pole section and the internal wiring tube. 2. A joint for use in a lowering pole assembly as claimed in claim 1, wherein the upper pole section is receivable inside a receiving sleeve. 3. A joint for use in a lowering pole assembly as claimed in claim 2, wherein the receiving sleeve forms part of the lower pole section. 4. A joint for use in a lowering pole assembly as claimed in claim 2, wherein the receiving sleeve is connected to the upper portion of the joint. 5. A joint for use in a lowering pole assembly as claimed claim 2, wherein the internal wiring tube includes a first end that protrudes from an open end of the receiving sleeve along the longitudinal axis. 6. A joint for use in a lowering pole assembly as claimed in claim 5, wherein the upper pole section is rotationally coupled to the lower pole section about an axis of rotation, and wherein the axis of rotation intersects the first wiring passage and the second wiring passage. 7. A joint for use in a lowering pole assembly as claimed in claim 5, wherein the upper pole section is rotationally coupled to the lower pole section about an axis of rotation, and wherein the axis of rotation is coaxial with the first wiring passage and the second wiring passage. 8. A joint for use in a lowering pole assembly as claimed in claim 1, wherein at least one of the lower portion of the joint and the upper portion of the joint includes a junction box module. 9. A joint for use in a lowering pole assembly as claimed in claim 1, wherein the lower portion and the upper portion each include a pole adaptor mounted at an operative angle to the axis of rotation. 10. A joint for use in a lowering pole assembly as claimed in claim 9, wherein each pole adaptor is substantially cylindrical and the longitudinal axis of the cylindrical pole adaptor of the lower joint portion and the longitudinal axis of the cylindrical pole adaptor of the upper joint portion are coaxial or offset. 11. A joint for use in a lowering pole assembly, the lowering pole assembly including: a lower pole section andan upper pole section having an internal surface, the upper pole section being moveable relative to the lower pole section, the joint including: a lower portion defining a first central wiring passage which is fixed relative to the lower pole section;an upper portion defining a second central wiring passage which is fixed relative to the upper pole section, the second central wiring passage communicating with the first central wiring passage; andan internal wiring tube communicating with the first central wiring passage and the second central wiring passage, the internal wiring tube being parallel to the upper pole section, the internal wiring tube having an overlap portion with the upper pole section formed by an annular space between the internal surface of upper pole section and the internal wiring tube, the overlap portion providing a water flow resistance between the upper pole section and the internal wiring tube.
