5. The electrical panel according to claim 1 , wherein said first protrusion and said second protrusion are configured to enable a locking device to lock said first protrusion to said second protrusion.

6. The electrical panel according to claim 1 , wherein at least one of the electrical components is configured to be coupled to a receptacle having a connector accessible from outside the housing.

7. The electrical panel according to claim 1 , wherein said compartment door is fabricated from a first material, and said barrier panel is fabricated from a second material that is different from the first material.

8. The electrical panel according to claim 1 , wherein said housing further comprises a faceplate and said compartment door is hingedly attached to said faceplate.

9. The electrical panel according to claim 1 , wherein said housing further comprises a faceplate and at least one of said faceplate and said shutter door assembly comprises an insulating material.

10. A shutter door assembly for an electrical panel housing, said shutter door assembly comprising:

a compartment door configured to be coupled to the housing and having at least one opening; and

a substantially planar barrier panel having at least one opening and slidably coupled to said compartment door, said barrier panel configured to be placed in a closed position that blocks the at least one compartment door opening and an open position wherein the at least one barrier panel opening is in alignment with the at least one compartment door opening, said compartment door comprising a first protrusion and a slot elongated in a sliding direction of said barrier panel, said barrier panel comprising a second protrusion that projects outwardly through the slot, wherein said first protrusion aligns with said second protrusion in at least one of the closed position and the open position.

11. The shutter door assembly according to claim 10 , further comprising at least one guide bracket coupled to said compartment door and said barrier panel, said at least one guide bracket configured to maintain alignment of said barrier panel with respect to said compartment door.

12. The shutter door assembly according to claim 10 , wherein said barrier panel is configured to slide relative to said compartment door between the closed position and the open position.

13. The shutter door assembly according to claim 12 , wherein said at least one barrier panel opening is configured to align with at least one electrical component housed in said housing when said barrier panel is in the open position.

14. The shutter door assembly according to claim 13 , further comprising a locking device configured to lock said first protrusion to said second protrusion.

15. The shutter door assembly according to claim 10 , wherein said compartment door is hingedly attached to said housing.

16. A method of assembling an electrical panel comprising:

providing a housing configured to house at least one electrical component; and

coupling a shutter door assembly to the housing, the shutter door assembly having a compartment door having at least one opening and a substantially planar barrier panel slidably coupled to the compartment door, the barrier panel configured to be placed in a closed position that obstructs access to the at least one electrical component through the compartment door and an open position that provides access to the at least one electrical component through the compartment door, the compartment door including a first protrusion and a slot elongated in a sliding direction of the barrier panel, the barrier panel including a second protrusion that projects outwardly through the slot, wherein coupling the shutter door assembly to the housing comprises slidably coupling the barrier panel to the compartment door such that the first protrusion aligns with the second protrusion in at least one of the closed position and the open position.

17. The method according to claim 16 , the barrier panel having at least one opening, wherein coupling the shutter door assembly to the housing comprises hingedly coupling the compartment door to the housing and slidably coupling the barrier panel to the compartment door such that at the least one barrier panel opening is configured to align with at the least one compartment door opening in the open position and the barrier panel is configured to slide relative to the compartment door between the closed position and the open position.

18. The method according to claim 17 , further comprising coupling a locking device to the shutter door assembly.

19. The method according to claim 16 , further comprising hingedly coupling the compartment door to the housing.
