An atmospheric vent system for a busway enclosure of an outdoor busway system comprises a connector housing assembly of the outdoor busway system. The connector housing assembly comprises first opposed metal side plates bolted together with second opposed metal plates that are aligned perpendicularly at either end of the first opposed metal side plates such that the connector housing assembly forms a connector housing which includes one or more atmospheric vents affixed into either of sides or ends of the connector housing. Each atmospheric vent of the connector housing having an elastomeric body and a spherical weight that is moveably restrained such that an internal wall engages the spherical weight to create a seal. ## Claims ### Claim 1 An atmospheric vent system for a busway enclosure of an outdoor busway system, the outdoor busway system comprising: a connector housing assembly of the outdoor busway system, wherein the connector housing assembly comprises first opposed metal side plates bolted together with second opposed metal plates that are aligned perpendicularly at either end of the first opposed metal side plates such that the connector housing assembly forms a connector housing which includes one or more atmospheric vents affixed into either of sides or ends of the connector housing, and wherein each atmospheric vent of the connector housing having an elastomeric body and a spherical weight that is moveably restrained such that an internal wall engages the spherical weight to create a seal. ### Claim 2 (depends on 1) The system of claim 1, wherein each atmospheric vent of the one or more atmospheric vents being fixedly sealed in a housings side of the first opposed metal side plates or an end of the second opposed metal plates and oriented in an upright position where a force of gravity causes the spherical weight to close. ### Claim 3 (depends on 1) The system of claim 1, wherein in the elastomeric body a circumference of the spherical weight is in an intimate contact about a diameter of a circumferential inner wall feature thus preventing passage through a first opening. ### Claim 4 (depends on 1) The system of claim 1, wherein each atmospheric vent of the one or more atmospheric vents being fixedly sealed in a housings side of the first opposed metal side plates or an end of the second opposed metal plates and oriented in an inverted position where a force of gravity causes the spherical weight to open. ### Claim 5 (depends on 1) The system of claim 1, wherein in the elastomeric body the spherical weight is disposed downwardly exposing second openings and allowing passage through a first opening. ### Claim 6 (depends on 1) The system of claim 1, wherein the elastomeric body comprises: a molded low durometer elastomer having a blunt end shape and having an external channel about its circumference and further having a through hole disposed between the blunt end shape and the external channel. ### Claim 7 (depends on 6) The system of claim 6, wherein the elastomeric body further comprises: an internal shape that is largely void and having a diameter determined to exceed a diameter of the spherical weight and where a circumferential inner wall feature is angled to receive the spherical weight and disposed between the external channel and the through hole. ### Claim 8 (depends on 7) The system of claim 7, wherein the spherical weight comprises: a non-corrosive metal or polymer where an outer spherical surface is essentially smooth and having a weight determined to seal with an angled wall of the circumferential inner wall feature of the elastomeric body. ### Claim 9 (depends on 1) The system of claim 1, wherein a shape of each atmospheric vent of the one or more atmospheric vents is determined in order to attach and seal with a panel of an enclosure housing. ### Claim 10 (depends on 1) The system of claim 1, wherein a determined orientation of each atmospheric vent of the one or more atmospheric vents is configured to: a. prevent movement through a passage b. allow movement through a passage, c. prevent passage while an atmospheric pressure exceeding that of its environment is released. ### Claim 11 A method of providing atmospheric venting in a busway enclosure of an outdoor busway system, the method comprising: providing a connector housing assembly of the outdoor busway system, wherein the connector housing assembly comprises first opposed metal side plates bolted together with second opposed metal plates that are aligned perpendicularly at either end of the first opposed metal side plates such that the connector housing assembly forms a connector housing which includes one or more atmospheric vents affixed into either of sides or ends of the connector housing, and wherein each atmospheric vent of the connector housing having an elastomeric body and a spherical weight that is moveably restrained such that an internal wall engages the spherical weight to create a seal. ### Claim 12 (depends on 11) The method of claim 11, wherein each atmospheric vent of the one or more atmospheric vents being fixedly sealed in a housings side of the first opposed metal side plates or an end of the second opposed metal plates and oriented in an upright position where a force of gravity causes the spherical weight to close. ### Claim 13 (depends on 11) The method of claim 11, wherein in the elastomeric body a circumference of the spherical weight is in an intimate contact about a diameter of a circumferential inner wall feature thus preventing passage through a first opening. ### Claim 14 (depends on 11) The method of claim 11, wherein each atmospheric vent of the one or more atmospheric vents being fixedly sealed in a housings side of the first opposed metal side plates or an end of the second opposed metal plates and oriented in an inverted position where a force of gravity causes the spherical weight to open. ### Claim 15 (depends on 11) The method of claim 11, wherein in the elastomeric body the spherical weight is disposed downwardly exposing second openings and allowing passage through a first opening. ### Claim 16 (depends on 11) The method of claim 11, wherein the elastomeric body comprises: a molded low durometer elastomer having a blunt end shape and having an external channel about its circumference and further having a through hole disposed between the blunt end shape and the external channel. ### Claim 17 (depends on 16) The method of claim 16, wherein the elastomeric body further comprises: an internal shape that is largely void and having a diameter determined to exceed a diameter of the spherical weight and where a circumferential inner wall feature is angled to receive the spherical weight and disposed between the external channel and the through hole. ### Claim 18 (depends on 17) The method of claim 17, wherein the spherical weight comprises: a non-corrosive metal or polymer where an outer spherical surface is essentially smooth and having a weight determined to seal with an angled wall of the circumferential inner wall feature of the elastomeric body. ### Claim 19 (depends on 11) The method of claim 11, wherein a shape of each atmospheric vent of the one or more atmospheric vents is determined in order to attach and seal with a panel of an enclosure housing. ### Claim 20 (depends on 11) The method of claim 11, wherein a determined orientation of each atmospheric vent of the one or more atmospheric vents is configured to: a. prevent movement through a passage b. allow movement through a passage, c. prevent passage while an atmospheric pressure exceeding that of its environment is released.
