Multiple Panels Linked
First of all I did search on this and I was not able to find a clear answer. I know this will work but I want to know if this would be a legal setup.
I have a large outdoor area that I need to get power to in specific locations. I’m running 4/0 from the main box on a breaker to the first box. This would then go to the second, to the third, etc. Do I need to have a breaker in each box to feed the next panel or can I link them together by joining the 4/0 from box to box. Secondly I would assume that every panel would need to have the same amp rating or a greater amp rating then that of the breaker in the main box. Correct?
Also these are all outdoor boxes. Do I need to keep the ground isolated or can I either run a ground rod at each box or bond to neutral at the boxes?
Now this is more of a hypothetical question at this point but my setup will make these boxes basically fall in a circle. Would there be any advantage or issue to complete the circle with another run of 4/0 to allow alternate path for the current to flow?

Welcome to the forums.
Your use of the word box makes things a little ambiguous - you are using it to refer to a subpanel and not a junction box, right?

Ok the loads will depend on what is connected and running. I do not need 200 amps to each box. I have a 100amp breaker feeding these panels. At some point it may be upgraded to a 200amp if need be. Running 4/0 because of distance to the panels. The panels will all daisy chain off each other. Do I need to have a breaker in each box feeding the next box or can I join them all together assuming no box can pull more then the breaker. Basically the one breaker will feed multiple boxes in series. Doing this to avoid having a 100 amp breaker in each box.

I guess I should phrase it as can one breaker feed multiple sub panels
provided that the breaker is smaller or the same size as the smallest amp rating on the panels.
.

would each sub panel need a disconnect breaker?
Also would I need to run a ground wire to each panel or can I ground to earth?

Need to know what you are going to use these for as different codes apply. Are they to be mounted on pedestals for an RV park? Or mounted on permanent structures.

OK - I think I have it down now. Just to recap it would be ok to have my main cable run from sub to sub as long as I have a breaker smaller then the smallest rated box. Boxes with more then 6 need to have a disconnect of some kind in them. I guess now we need to do a wire ground as well as a rod? I don't think it was like that a few years back when we started putting these in. I think the rod was all that was required,

I haven't seen 4/0 quad

Do your panels have feed through lugs? How do you propose feeding each additional panel from the previous panel?
