Glad it was as simple as a loose connection.

The connectors in the fuse/breaker panel do a lot of heating and cooling due to power loading.

Before you try to fool with the terminals in the panel, try this.

Take the breaker out of the panel and "tweek" the spades slightly.

OK the spades look like so _ _ now if you very gently twist these with a needle nose pliers, ever so slightly. Holding the breaker and looking straight at the ends of the prongs, tweek them like you were going to wind them in a circle. It will only take a little bit on each one to force them to fit more snugly in the slots of the breaker box.

Trying to fool with the breaker box can have catastrophic results. Ask me how I know this.

The other way is to grab each spade with two pliers, on opposite side and tweek them ever so slightly to make them sort of like a tiny V.

The other way is to lay the breaker spades on a flat piece of steel, and using a center punch and a hammer (very small one) lightly dimple the spades. NOW I MEAN LIGHTLY just rasie some bumps that will cause the spades to fit snug in the terminals.

The slight twist usually works about the best

A few options.

Good luck
