While we are on this topic I would like to pose a question...not to hijack the thread:
Many years ago, a instructor I had in my 3rd year apprenticeship, was explaining about how a breaker can store energy, enough to kill you if you closed it. If I remember correctly it was along the lines of say there is a lightning strike, the utilities circuit breaker is antiquated and doesn't open. Current travels through line to residence or building with improper grounding. That or some of the e=nergy could store in your tripped main. seems impossible however he was pretty convincing! You reset breaker and that energy comes out of panel and basically cuts you in half. I have never read or heard of this.
1) Is this possible?
2) Have any of you heard of this?

If so, a 0 Risk for resetting tripped breaker with panel cover on seems egregious.
