Proper Labeling?

I have a number of single phase panels mounted on hand trucks ranging from 6 to 20 space. I would label them 120/240V, but they are often also run on 2 legs of a 3 phase wye, making them 120/208V. What is the "Proper" way to label them? I've been marking them "XA 120/208-240V 1" Is that the correct way?

240v and 208v are many cases used interchangeably. 240v is the max voltage so it would also cover 208v

I don't know of any code requirement for labeling, but IMO what you are doing is fine.

That's what I figured, but what made me question is there are no pre-made labels that say 120/208-240V or even 120/208/240V.
