Connecting 2 Honda EU2000i

Most of parts assembled
2 2' 12/3 cords from Wallymart, plastic conduit box and hinged cover from HD, pair of 20A/125v plugs to replace the bananas on the other box.

Prep the cables
First lop off the tripple receptacles, then cut the outer jacket back about 3", trim off the cording, and strip each lead about 3/8 inch

Glue-lined tubing
The cords are inserted into the conduit box (with dual 1/2" fittings) after threading on the shrink tubing.

Leads prepared to insert in receptacle
The leads are color-matched, then inserted into the designated terminals on the receptacle.

Assembled & Ready to Shrink
Here the receptacle and hinged cover are attached to the Conduit box; note I changed to 1" #6 screws vs those with the receptacle.

Starting to shrink
The glue-lined shrinkable splice tube stays soft for a while; I learned I have to do it in two stepsA: first the shrinkdown onto the conduit box fitting. when the glue is cool and set so that shrinkage of the upper part won't pull it off the fitting, carefully shrink the upper for a tight and sealed fit to the cable.

All done. Just like downtown.
Finished product at around $30; I like it better than the $236 version, but then....

All done and running
The cords replace both the bananas and the ground leads on the Honda version. Since the bananas and ground terminals are essentially the same as the outlets (except the outlets aresafer, they are protected by the Honda circuit breaker)all the connections of the Honda version are in place. Use of the Ground lug is optional; there is no possibility of polarity reversal because both outlets are forced into the same polarity by the polarized 12/3 plugs.

Behind the panel
Output goes direct to bananas, and to receptacle thru breaker, but otherwise a direct connection.

Prior Box Modified,Connected, and running
This is the original Near Final box. Here the polarized 20A plugs have replaced the polarized bananas which I could not find in shrouded versions. The possibility of kicking out one of these plugs is remote, since the extraction forces are about 50 times greater than the bananas. For those still concerned, I experimented with half of a squash ball with small slits to thread over the 3 prongs. Insert the plug, and the concave half-ball flatens out. Pull the plug, it pops back into an insulating shield around the plug tips. Not elegant, but servicable for those so inclined to super-safety. Step 2, the Duckbutt Fix, replaced the squash ball with rubber duckies, shown in another gallery.
