Wire from Multiplus II 2x120 to AC breaker Panel

[gr8pix]

Hello, I'm planning on picking up this 6/3 w/ground wire for my RV 50A - 24v Multiplus II 2x120 install.

Would there be any safety issues with running this from the breaker panel and back or can someone please recommend?

Thanks!
Walter

That wire looks to be correct for that amp rating, I ran the same wire in my 50A panel fifthwheel, from my multiplus 2x120
if that wire is exposed be careful to protect it.

That wire will only have a few strands in the multi strand wire. It will not be very flexible. You may be better off looking for some Marine wire that is 6/3+ground.

I found this 6/4 cord that it is “extension cord” type. Yes more flexible- you will need Ferrells for the ends and it costs more - but it may be worth it because it is more flexible. (Luckily I don’t have to run that cable ?).

Thanks very much for the info! I ended up going with 6/4 SOOW cable because I routed under the coach, disconnected the shore power wire from breaker panel then spliced it with the SOOW to the Multiplus and then back to the breaker. I have to finish securing the wire tomorrow. It's a lot heavier than the Romex, more flexible & really expen$$$ive :-(

Thanks Rocketman! I ended picking up the SOOW reluctantly, and the stuff weights a ton, I needed 50 feet of the stuff, and you're right about the Ferrules, the strands are really fine. Tomorrow I'm securing all 50ft of it and wrapping it split loom, a ton or work. After that's done I have to run 325ft of PV wire, I'll be glad when the cabling is done! Cheers!

I finally finished running my 50ft of 6/4 SOOW cable and was easier than I thought it would be although tedious securing the wire every 12 in or so. I have a couple of questions before splicing the AC OUT from the Multiplus II to my existing breaker panel.
Is a 50A breaker needed for the AC IN line from shore power to the Multiplus II? The pedestal has a breaker as well I'm protected by a surge guard, should I add another 50A Dual Breaker to this line?

In the Multiplus II Manual it says that the AC-OUT-1 should be outfitted with a 75A circuit breaker to enable the power assist feature. Would anyone know about this?
Thanks!
