You need to also comply with article 525.

Flexible cords do not have uninsulated grounds.

As there is nothing to assure that every other circuit is turned off I feel it would be prudent to count the neutral as a CCC. In this case the reduced ampacity would apply.

You I can forgive for not knowing the terms, but your electrical supply shop ought to know better!

And since I happen to work at a supply shop, I figured that you meant 8/4 because I hear people call it 8/3 with ground all the time. Common mistake.

That's just your opinion. But not a bad one either.

Now I see a bad plan. You would need to install an inlet on your concession stand not an outlet.

Reason being that the exposed parts on the male cord end will/could be live.

The 50 amp female box is an inlet for the male plug. Am I right about that? Any other issues with the diagram?

Refer to RV wiring to campsites. Keep in mind that campsites provide 30a 110 or 50a 110....thats a difference. But the lead power cord between rv and campsite is the same.

The inlet box needs to be male so you do not have live ends of the cord exposed.

I have been thinking about this whole neutral as a CCC thing and one thing that wasn't mentioned was that in your OP you are stating the voltage as xxx/220, but I don't remember seeing of it was three phase or single phase.

It is not clear which you actually have, but a three phase service doesnt seem out of the question for this type of setting. If it is a three phase service, you will have to count the neutral as a CCC when using 8/3 W/ground SOW.

You are right. Just had a honda manufacturing electrician look at it. The male into box needs to be female and the box needs to be male. Also.....would be better to run 30 amp main and be well under for the 100 foot run. Thank you.

Single phase.
