Power inlet box with integral circuit breaker

In an electrical enclosure having a housing including a base member defining an internal cavity and a cover member removably interconnected to the base member for enclosing the internal cavity, a power inlet mounted to the housing within the internal cavity, and a switching mechanism supported in the housing within the internal cavity, the improvement comprising:

• a mounting assembly secured to the housing within the internal cavity and electrically connected to the power inlet for supporting the switching mechanism in a friction fit arrangement wherein the mounting assembly is defined by
• an insulated base plate having stab structure frictionally and electrically engageable with the switching mechanism for supporting the switching mechanism along one portion thereof;
• a retainer plate having foot structure for supporting the switching mechanism along another portion thereof;
• and
• a support bracket having attachment structure for attaching the support bracket to either the base member or the cover member,
• the base plate, the retainer plate and the support bracket being interconnected together,
• wherein the foot structure of the retainer plate includes at least one upwardly extending projection engageable with notch structure formed on the switching mechanism,
• wherein the support bracket is a generally U-shaped member defined by a bight portion and a pair of spaced apart leg portions, each of the leg portions being provided with the attachment structure in the form of a laterally extending attachment portion, and
• wherein the attachment structure is connected to a front wall of the cover member, a front surface of the retainer plate is placed against an external surface of the bight portion, and a rear surface of the base plate is placed against an internal surface of the bight portion.
