Thank you both, Frenchie and A7E, for your response. I'll do my best here to fill in the details.

Frenchie, when you ask for size of the conductor, what are you referring to? Is it the gauge of the wire, or the size of the load? The wire is 8 gauge I believe, and the panel lugs are aluminum.

The grounding bus bar is a 50 ft run from the sub panel. It's on a main panel installed by a licensed electrician.

Below is a photo of the whole panel as requested.

A7E, are your questions answered by this new photo?

thanks again,
JDK

Not sure if this is your only problem, but if the shed/shop is detached, I believe you need a ground rod close to your sub-panel.
