Food trucks or campers

[geochurchi]

Would a food truck or camper be considered a sub panel?in which case the neutrals and grounds would be isolated with the bond screw removed.

In most cases yes.

In most cases yes.

...and about a third of them are wired incorrectly....

That was what I was getting at.

They should all be wired as sub panels but DIY ones are often a mess.

And most have a 50 amp rated cord with 80 amps of load.

Too bad about the 50a breaker... No, I'm not changing that out, thanks for asking. :lol:

I used to hook up a lot of concert power from good sized to small. Anyway this Kiss cover band 'roadie' brings me the end of a 6/4 cord and tells me he has to have the cord connected too '220, 200 amps two phase' for his lighting rig.

I gave him 208/120 at 60 amps, the shows went fine.

Yes
Carnivals and Fairs are not as common as they once were, however any kind of temporary concessions or food cart seems to fall under "similar event". A vehicle or cluster vehicles in a food truck area seem to meet the intent Article 525. Thus 525.31 would apply. Also 551.4 addresses RV's not used as RV's. The intent of all NEC codes dealing with any kind of food truck is the neutrals should be floated.
When we get calls to remove broken or unused hot tubs I always save the GFCI, so we have a few laying around that I pass on when installing the requested 120/240 50A receptacle for food trucks. The breaker trips 90% of the time.
