Acceptable Methods of bypassing meter main feeds to ATS and back

[Jsun]

Hello. I have been having a hard time trying to figure out what is the best, most efficient, safe and code acceptable way to bypass the main feeds coming off a residential meter main and bringing them over to my transfer switch. I have done genset jobs before but never really came across the problem I am having now. I have these older GE and Siemens meter mains that have a 4 pole 200 amp breaker as the main in the distribution side which is being fed off the meter section by 4 #2 THHN conductors in parallel. The problem is obvious and being that my transfer switches only ever have 2 lugs for in and out how am I supposed to feed this and re-feed the main when I have 4 conductors that need to land there?. my main thought is to just get some 3 port polaris caps and combine both A phase legs together with one 3/0 coming out to go to my transfer switch and same for B phase, only I will have to do the exact opposite as it leaves the transfer switches 2 conductor set up and needs to be returned as 4 conductors in parallel to land properly on the existing 4 pole 200A main breaker in main panel. This seems like it would work just fine and I think it falls under some of the tap rules possibly but I'm just not sure what inspectors would think. Also been curious of the ability to tap new lugs onto the load side of the meters bussing so instead of having the parallel feeds I could install 3/0 lugs and just come off with 2- 3/0 conductors from the beginning, only then i would have to figure out a different main breaker as the existing one would still be a 4 pole only capable of accepting the #2 parallel conductors.. Any help is appreciated I've been going in circles on this trying to keep from having to replace the whole meter main, its already pricey enough for the customer having to get a genset.

In my opinion the equipment needs to be replaced, you cannot parallel conductors smaller then 1/0, & the existing parallel conductors are part of listed equipment.

What's on the load side of the meter main? Does it feed into a buss or is there wiring to a panel?

Use a lug block to give you a 200a subfeed, feed the transfer switch with that, have the transfer switch feed a subpanel. Extend the circuits that you want backed up that were in the meter main to the subpanel.
