A service disconnect assembly for an electric system is provided and may include a service disconnect base electrically connected to the electric system and a service disconnect plug connected to the service disconnect base in a connected state to supply the electric system with power via the service disconnect plug and disconnected from the service disconnect base in a disconnected state to prevent the supply of power to the electric system. The service disconnect assembly may additionally include a lockout plug connected to the service disconnect base when the service disconnect plug is in the disconnected state to prevent the service disconnect plug from inadvertently being moved into the connected state.

1. A method comprising: moving a first latch mechanism associated with a service disconnect plug from a latched state to an unlatched state;removing said service disconnect plug from engagement with a service disconnect base;inserting a lockout plug into said service disconnect base;moving a second latch mechanism associated with said lockout plug from an unlatched state to a latched state to secure said lockout plug to said service disconnect base; andmoving a locking mechanism associated with said lockout plug from an unlocked state to a locked state to prevent inadvertent movement of said second latch mechanism from said latched state to said unlatched state wherein preventing movement of said second latch mechanism from said latched state to said unlatched state includes moving one of a combination lock or a pad lock into a locked state to restrict movement of said second latch mechanism relative to said service disconnect base. 2. A method comprising: moving a first latch mechanism associated with a service disconnect plug from a latched state to an unlatched state;removing said service disconnect plug from engagement with a service disconnect base;inserting a lockout plug into said service disconnect base;moving a second latch mechanism associated with said lockout plug from an unlatched state to a latched state to secure said lockout plug to said service disconnect base; andmoving a locking mechanism associated with said lockout plug from an unlocked state to a locked state to prevent inadvertent movement of said second latch mechanism from said latched state to said unlatched state wherein preventing movement of said second latch mechanism from said latched state to said unlatched state includes moving a locking arm toward said second latch mechanism to restrict movement of said second latch mechanism relative to said service disconnect base. 3. The method of claim 2, wherein restricting movement of said second latch mechanism relative to said service disconnect base from said latched state to said unlatched state prevents removal of said lockout plug from said service disconnect base. 4. The method of claim 2, wherein preventing movement of said second latch mechanism from said latched state to said unlatched state includes moving one of a combination lock or a pad lock into a locked state to restrict movement of said locking arm relative to said service disconnect base. 5. A service disconnect assembly for an electric system, the electric system having a power source and a load, the service disconnect assembly comprising: a service disconnect base electrically connected to the electric system;a service disconnect plug operable to be connected to said service disconnect base in a connected state to supply the load of the electric system with power from the power source via said service disconnect plug and operable to be disconnected from said service disconnect base in a disconnected state to prevent the supply of power from the power source to the load of the electric system; anda lockout plug operable to be connected to said service disconnect base when said service disconnect plug is in said disconnected state to prevent said service disconnect plug from inadvertently being moved into said connected state;wherein said service disconnect plug includes a first latch mechanism operable in a latched state to secure said service disconnect plug to said service disconnect base when said service disconnect plug is in said connected state and said lockout plug includes a second latch mechanism operable in a latched state to secure said lockout plug to said service disconnect base when said lockout plug is connected to said service disconnect base;wherein said lockout plug includes a locking mechanism operable in a locked state to restrict movement of said second latch mechanism relative to said service disconnect base to prevent inadvertent removal of said lockout plug from said service disconnect base; andwherein said locking mechanism includes a locking arm in selective engagement with said second latch mechanism to prevent movement of said second latch mechanism from said latched state to an unlatched state. 6. The service disconnect assembly of claim 5, wherein said first latch mechanism and said second latch mechanism are substantially identical. 7. The service disconnect assembly of claim 5, wherein said locking mechanism contacts said second latch mechanism to prevent movement of said second latch mechanism from said latched state to an unlatched state. 8. The service disconnect assembly of claim 5, wherein said locking mechanism includes one of a combination lock or a pad lock in selective engagement with said locking arm to restrict movement of said locking arm relative to said service disconnect base. 9. The service disconnect assembly of claim 5, wherein the electric system is an electric system for an electric vehicle. 10. The service disconnect assembly of claim 9, wherein the load of the electric system includes an electric motor of the electric vehicle and said service disconnect plug includes a fuse operable to permit current to flow from said power source to the electric motor of said electric vehicle when said service disconnect plug is in said connected state. 11. The service disconnect assembly of claim 5, wherein said service disconnect plug includes a first housing matingly received by said service disconnect base when said service disconnect plug is in said connected state and said lockout plug includes a second housing matingly received by said service disconnect base when said lockout plug is connected to said service disconnect base. 12. The service disconnect assembly of claim 11, wherein said first housing and said second housing are substantially identical to allow said first housing and said second housing to be interchangeably attached to said service disconnect base. 13. A service disconnect assembly for an electric system, the electric system having a power source and a load, the service disconnect assembly comprising: a service disconnect base electrically connected to the electric system;a service disconnect plug operable to be connected to said service disconnect base in a connected state to supply the load of the electric system with power from the power source via said service disconnect plug and operable to be disconnected from said service disconnect base in a disconnected state to prevent the supply of power from the power source to the load of the electric system; anda lockout plug operable to be connected to said service disconnect base when said service disconnect plug is in said disconnected state to prevent said service disconnect plug from inadvertently being moved into said connected state;wherein said lockout plug includes a latch mechanism operable in a latched state to secure said lockout plug to said service disconnect base when said lockout plug is connected to said service disconnect base;wherein said lockout plug includes a locking mechanism operable in a locked state to restrict movement of said latch mechanism relative to said service disconnect base to prevent inadvertent removal of said lockout plug from said service disconnect base; andsaid locking mechanism includes a locking arm in selective engagement with said latch mechanism to prevent movement of said latch mechanism from said latched state to an unlatched state. 14.
