Review on KEEPDSGN Circuit Breaker Inverter Replace Industrial Electrical by Jordan Jackson

Red plastic lever marked 40A goes through a hole in the top which is too big and a slack in the lever enables the lever does not reach the stop contacts do not touch. You push him all the way down and the connection is made, let go and he loses it. Second is the contact surface, both are convex rather than flat which means very little contact. Less contact means poor connection and more heat.
