recently the lights in kitchen started flickering, then they went out last night (my fridge is also on the line and went out) Electric to rest of house ok. The double pole circuit breaker in my box didnt trip, I switched it to off and then to on position and power went back on, but again it went out without the breaker tripping. Should i try changing the breaker, i am thinking it's a faulty wire or damaged connection or bus bar problem behind breaker...should i try changing the breaker? strangely it was also raining last night...and its fine today...could this be a problem from outside where electric comes into house(could moisture effect only that breaker?) Any help would be greatly appreciated???

They are caused by a loose connection. As the current decreases it won't trip a breaker.

Connections to the breaker and the breaker to the bus (and internal to the breaker) is one place that might happen.

If you have a poor connection to the POCO supply it can also cause flickering. But that will only affect the loads on one leg. But depending on what is in use at the time and which leg they are on you might not realize that the problem affects more than one circuit.

Are you sure you are checking the right breaker?

You say the "double pole circuit breaker" didn't trip, but it is unlikely that kitchen lights or refrigerator would be on a double-pole breaker. That's more likely the breaker for the electric stove. Both the lights & the refrigerator are 120V appliances, and should be on a single-pole breaker.

Also, breakers can 'trip' without physically moving the handle much. They may look like they are still on, but turning them off and back on again will reconnect the circuit.

You may also have a loose neutral wire, either at the connection to the neutral bar in the panel, or at a junction box (which could be a switch or receptacle).

Tim: It is possible to have a double pole breaker controlling 120V circuits if it is a multiwire circuit (two hots, common neutral).
