Connecting Neutral & Ground from Generator to Home

Worse than just having 240vac, any 120vac loads will have floating neutral so the 120vac house outlets will have varying voltage depending on how much 120vac loads are on each side of L1, L2 to neutral. Very unsafe and hazardous to 120 vac appliances plugged in. Very bad design! Shows total lack of understanding of U.S. split phase system. So can you believe the cord #2 plugged into one generator L14-30 outlet to house service entry is correct ???
Understood, and a concern I tried to address by installing meters - below from a couple weeks back was at the 2 generator HOT legs entering MAIN. Does this cancel your concern (I HOPE) for varying voltage?

I think part of your comment is at heart of my issue (concern) - "how to apply Neutral in this case". I wonder if it's something similar to installing High Frequency Inverters? How 240v is split when coming into homes from a transformer isn't same, and maybe source of this problem? My mind is parked on idea that AC needs to return or cycle back to source (the generators or home panel?).

YES, the L14-30 at the generator control panel works (how below readout was connected - so maybe I stop there and full-load test (I was successful in partial load testing the micro and HVAC fan).

NO, I wasn't successful testing Cord #1 (NEMA 10-50) and fried 2 power strips.

Replace 10-50 with 14-50 socket.

Connect L1, L2, and ground as was with 10-50 socket.

Remove white neutral wire splice and connect them together on neutral of 14-50 socket.

I like that - what was suggested a long time ago, but I was too cheap to save the terrible $40 piece junk.

I know that the L14-30 works (in parallel mode), which includes a neutral.
I know the banana lead on generator control panel has continuity to generator neutral.

As you say, it seems I'm just upgrading the cheap (30A) plug for a 50A plug ;--(

Either I'm going to make a new box, or buy another parallel kit, that maybe includes a circuit breaker, or better yet, a breaker ON/OFF switch.
So much for the cheaper solution - you gets what yous pays for.

Well if at first you don't succeed, go to DIY Solar Power Forum for input you want to hear, and maybe even input you don't want to hear.

After plenty of research (and input) I came to conclusion the parallel kit sold with my generator was junk with old NEMA 10-50, so I replaced with NEMA 14-50.

Successfully tested my homemade parallel box with the new 14-50 today, ran microwave, sump pump as well as lights etc. Further load tests to follow, i.e. furnace etc.

Don't like the cheap volt / amp meters I went with and wouldn't recommend as the display is hardly visible. I tried putting copper tape on one but still bad.

THANKS ALL FOR YOUR CONTRIBUTIONS ! (y)
