Cathedral door shutter assembly

A shuttered bus assembly for a circuit breaker housing assembly, said circuit breaker housing assembly structured to enclose a circuit breaker assembly, said circuit breaker assembly structured to move generally horizontally in and out of said circuit breaker housing assembly, said circuit breaker assembly further having a plurality of finger connectors extending generally horizontally from the back side of said circuit breaker assembly, said shuttered bus assembly comprising:

• a bus assembly having one or more pairs of line and load conductors which extend toward the front of said housing assembly and which are structured to be engaged by said finger connectors, said bus assembly couple to said housing assembly;
• said shutter assembly comprising:
• a mounting assembly structured to be coupled to said housing assembly;
• a door panel having at least one opening and at least one door member, said door panel extending across said housing assembly and disposed between said plurality of conductors and said circuit breaker assembly when said circuit breaker assembly is out of said housing assembly, said door panel further coupled to said mounting assembly;
• and
• said at least one door member disposed in said at least one opening and coupled to said door panel by a hinge, said door member structured to move between a first closed position and a second open position and which is structured to be moved to said second position by said finger connectors as said circuit breaker assembly is moved into said housing assembly.

A circuit breaker installation comprising:

• a housing assembly having a plurality of wall members forming a housing assembly;
• a circuit breaker assembly having a plurality of finger connectors extending generally horizontally from the back side of said circuit breaker assembly and which is structured to move generally horizontally in and out of said circuit breaker housing assembly;
• a shuttered bus assembly coupled to said housing assembly and comprising:
• one or more pairs of line and load conductors which extend toward the front of said housing assembly and which are structured to be engaged by said finger connectors;
• said shutter assembly comprising:
• a mounting assembly structured to be coupled to said housing assembly;
• a door panel having at least one opening and at least one door member, said door panel extending across said housing assembly and disposed between said plurality of conductors and said circuit breaker assembly when said circuit breaker assembly is out of said housing assembly, said door panel further coupled to said mounting assembly;
• and
• said at least one door member disposed in said at least one opening and coupled to said door panel by a hinge, said door member structured to move between a first closed position and a second open position and which is structured to be moved to said second position by said finger connectors as said circuit breaker assembly is moved into said housing assembly.
