A first electrical connector is configured to be removably coupled to a second electrical connector that includes a housing and a sleeve that depends from the housing. The first electrical connector includes a body having a longitudinal axis, an interface portion, and a circumferential groove formed in the interference portion. The groove is defined by a circumferential wall of the interference portion. A radial wall extends from the circumferential wall away from the longitudinal axis, and a circumferential extension extends axially from the radial wall. The radial wall and the circumferential extension are configured such that when the first electrical connector is coupled to the second electrical connector, the circumferential extension is snugly received in the sleeve of the second connector to form an air-tight chamber between the sleeve and the interference portion. As the first electrical connector is removed from the second electrical connector, an air flow path is defined around an end of the sleeve in a space between the circumferential extension and the sleeve to allow air to enter the chamber to inhibit flashover.
