Enhancing convection and cooling in a circuit breaker

A method for enhancing convection and cooling in a circuit breaker, the method comprising:

• providing a housing having a first portion and a second portion;
• providing one or more first orientation features formed onto the first portion of the housing;
• and
• providing one or more second orientation features formed onto the second portion of the housing such that the one or more first orientation features are different from the one or more second orientation features and the first portion of the housing is different than the second portion of the housing,
• wherein the one or more first orientation features and the one or more second orientation features are assembled together to form air channels to allow air to go in and out while preventing a solid object from protruding and from touching inside components of the circuit breaker.

A load center, comprising:

• a first circuit breaker including:
• a first housing,
• one or more first orientation features formed onto the first housing, and
• one or more second orientation features formed onto the first housing such that the one or more first orientation features are different from the one or more second orientation features,
• wherein the one or more first orientation features and the one or more second orientation features are assembled together to form a first air channel to allow air to go in and out while preventing a first solid object from protruding and from touching inside components of the first circuit breaker;
• a second circuit breaker including:
• a second housing,
• one or more third orientation features formed onto the second housing, and one or more fourth orientation features formed onto the second housing such that the one or more third orientation features are different from the one or more fourth orientation features,
• wherein the one or more third orientation features and the one or more fourth orientation features are assembled together to form a second air channel to allow air to go in and out while preventing a second solid object from protruding and from touching inside components of the second circuit breaker;
• and
• breaker housing features that allow the first and second circuit breakers to form openings or channels so that air flows in and out of the first and second air channels.
