Sparks are coming from circuit breaker in the main box. It feeds lighting and outlets in the house

So your first instinct is to post to an internet message board??

CALL AN ELECTRICIAN IMMEDIATELY.

Is it one breaker that is sparking?

Are u comfortable working with electric?

Shut off main breaker and remove breaker that is sparking. Check wires attached to breaker to make sure they are tight.

Check to see if wire was damaged by sparking.

There are other things to check. An electrician will be by to give more info.

Really? Shut the breaker and call and ELectrician NOW! If you had to ask, then you aren't qualified to work on it.
