Thanks to all of you for a bunch of great suggestions, much appreciated. I should have thought of this myself, but I didn't. Making another cable by installing 2 new ends, one female and one male is the best idea and most versatile option. As noted above, this will give me 3 options, my original 25 feet, a 20 foot or a 45 foot cord depending on my needs. In terms of load, my yam gen is a ef2800i so could not exceed the cord rating and my other option is 2 Honda eu2000s which combined is 27 amps, again within the cords specs. Will be picking up a new male and female connector today

Thanks again!

Just splicing it in the middle isn't good practice. Just get a male and female and a make another cord. This will give you greater flexibility in total length; you'll have 3 choices: 25, 20, or 45.
#10 is only rated for 30 amps so at 120v you can only put 3,600 watts thru the cord.


Best explanation splicing in the middle of a loose cord violates NEC.

I'm with the new ends group. Buy new ends and attach to what ever length you want(I'd use the entire piece), at about $20 for each connector, your set to go for up to 45 feet and someday you might need that extra 10 feet.

Is the Ranger going to stop by, whip out the NEC code book, then take a pair of dykes and cut his cord in half?

A splice if done correctly is nothing deserving drama.

since that offense enables entry without a search warrant, the Ranger will notice that the tags have been removed from his mattress.

I had too many RV plugs overheating when under heavier load (AC).
Splicing brings even higher risk of overheating and when you drop such cord in dry grass and you camp in California, next thing we hear about you is headlines

Even if you connect 2 cords with legal plugs, put the plugs in metal box.

Do you want a waterproof splice or just get the ends and make up an extension?

Top quality TT-30 connectors.

Heat shrink butt splice

If you splice the cord remove the RV end from the J-box and extend the tail. Don't cut the middle or the plug off. Seal it with heat shrink.

I would make an extension if temporary. Splice if long term.
Actually I would just get a longer pre-molded cord.

Do the splice correctly and it will last as long as the rest of the cable. The secret with using heat shrink like this stuff is to apply two or even three layers of it. I've never had a soldered splice fail. But I have had to repair countless other people's crimped failures. A crimped only connection in a wire or cable cord is a "death sentence". The cables flex unlike a regular set in place wire or cable.

Cold shrink is several times thicker than heat shrink, and is allowed by the nec for hydraulic spliced connectors on electrical wire. I have never looked in the code book to see if splicing SO, SJO, SOOW, is allowed, but I do not believe it is due to the fact that it interrupts the ability to keep tension from being applied to the conductors, and conductor terminals.

I cut up my portable surge guard and attached it to (partly) the bitter end of the shore power cord, and then (the other part) to the power centre as a permanent installation inside the shore cord lockable storage box. Probably against NEC but who cares about those foreign rules ? (Except ours are probably the same!)

The OP could add his extra length of #10 by adding the one end to it, but also by cleverly adding the other end to meet the surge guard end at the bitter end where it joins to the RV power centre since it is already "cut".
