Does a field installed main lugs have to have retaining clip? SER cable goes to the main lugs in panel. A second SER is also installed using the main lug kit. Does this kit need a retaining screw or clip?

I read that wrong...
Why would you have a retaining clip on the lugs? Aren't they already secure?
The retaining clip is for the backfed breaker.

What are you trying to do? Paralleling the SER? Or feeding another panel with the second SER? Plug in main lug adapter?

Hold down clip not needed then, it is treated just like a breaker. If it was backfeeding the panel, then yes, it would need a mechanical means to hold it in.

In this case you can always add the retaining clip at your discretion.

If it is a plug on type "sub feed lug kit" then make sure your incoming feeder lands on the fixed main lugs and outgoing feeder lands on the plug on kit and you are fine.
If it is bolt on breaker type panel - it is already mechanically secured by the bolt on connection method.
If using commercial type panelboards instead of "loadcenters" why not order them with feed thru lugs, basically you will have lugs at both the top and bottom of the buses and either end can be the supply or the feed thru.

It's a square d hotline panel. The sub feed lug kits don't have a retaining clip

Use main lugs for supply and sub feed lugs for outgoing
