A junction box assembly including a housing having an opening for accessing an interior of the housing, a high-voltage connector adjacent the opening, and an access panel mounted to the housing. The access panel is movable between a first position and a second position, the first position restricting access to the opening of the housing and permitting a cooperating high-voltage connector to engage the high-voltage connector adjacent the opening and the second position permitting access to the opening of the housing and restricting a cooperating high-voltage connecter from engaging the high-voltage connector adjacent the opening.
