The male end of a cordset was cut off going into this panel. I suspect a generator was used to feed the lower left 2 pole breaker since the black is stripped twice and isn't long enough to reach much else. Also found several breakers and neut's double lugged. Not a big deal but I thought it was kind of funny
Before we assume that was a backfeed- I must make a comment. I have somthing similar on my own panel in the basement, and what I do is when the power goes out, I pop the panel cover and connest the cords wires to my furnace, since it is the only appliance that I need that isn't cord-and-plug connected.
this kinda looks like a subpanel, with grounds on the neutral bars.... Nice cord grip by the way! Also, backfeeding both phases on one phase can allow shared neutrals to be overheated.. (Not that the extension cord here could carry enough current to do that though..)
As electricians, we may not agree 100% with what utilities require, but with a clear understanding of the very serious hazard backfeed can create for lineworkers, we should firmly support the prohibition of everything that has the potential of creating such a situation.
This means nothing but professionally installed, listed, lockable, externally-operable, visible-blade, center-off double-throw disconnect switches at the building meter location, and clearly rejecting any tin-can-grade breaker-handle “interlocks” intended for non-utility alternate-power sources.
[Backfeed attempts are also a top-flight way to fry generator sets.]
