220v wiring help

Since you didn't have the ground connected on the male end you should check the female end to see how it was wired.

If you can't post a pic of your 40A outlets

there is no nema rated 40a outlet. goes from 30a to 50a

This post has been brewing for a week. Imagine if the cover was taken off the panel and recepts pulled out of the box how much factual info that would yield.

Because my only 240 circuit is fed from the Main Panel both the Ground and the Neutral are landed on the same Buss Bar. If they came from a Sub Panel they would be landed separatly then I would use a fourth conductor for the neutral.

Ground and neutral are not the same, even though they are connected at the first point of disconnect.

What does your 240 circuit feed? Since it's a 240 circuit, you don't need a neutral. A 120/240 circuit needs a neutral. And all of them need a ground. Makes no difference if the source is a sub or a main panel.

I have a long cable that I use to power my Arc Welder and Table Saw. The cable has a receptical that can take the plug of either the Welder or Saw, but not both at the same time.

Even though neutral is bonded to ground at the main or first means of disconnect, they are vastly different downstream

EGCs/grounding conductors/bond wires do not carry current under normal circumstances…. On the other hand, neutrals/grounded conductors do carry current under normal circumstances.

Neither of those need a neutral

you are correct, but the third conductor grounds the equipment.
