Follow-up

I have my lights (fluorescent) coming off the main house panel and all
else coming off a sub panel for the shop. That way I can lock out all
machines and outlets when I have grand kids working in the shop.

The shop is in my basement and I believe that general circuits (those
not dedicated to a specific use) are required have a GFCI.

Don't think so.

If you follow that logic, EVERY receptacle in the house would
require GFCI protection which obviously is not the case.

Do you have water plumbed into your shop?

If so, you may require GFCI protection if receptacle close to
a water faucet, otherwise not.

Try replacing the GFCI receptacle with an industrial grade
receptacle (5262), which you may not be able to get at HD,
but may have to get from an electrical distributor.

It will be a heavy duty, 20A receptacle, that may cost as much
as $10 for a single unit.
