Connecting two 50 amp power cords

[time_traveler]

What adapter do I need?

50 amp twist lock to 50 amp RV

 

I believe this one should work, but you will need to verify, https://www.amazon.com/Parkworld-886399-Adapter-SS2-50P-14-50R/dp/B079JYS4GT/ref=asc_df_B079JYS4GT/?tag=hyprod-20&linkCode=df0&hvadid=241924658829&hvpos=&hvnetw=g&hvrand=17556146774675789746&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9033769&hvtargid=pla-451300218221&psc=1

The top pic is intended to connect to the RV, the second to the power pedestal. Use an extension cord, if you can't get close enough to the pedestal. 10 foot or 30 foot.

After seeing the last poster, there is more than one way to ready your question.  

I took your question to mean you wanted to connect those two together.  

What are you wanting to "adapt" to?

I want to connect the two 50 amp power cords I have for when I’m more than 25’ from the pedestal

The twist-lock pictured in the first post is a 30A cord. Note that it has only 3 pins. The adapter shown on Amazon should work fine as it is a 30A to 50A connector.

Look again, Kirk. There are three "prongs", two hots and the neutral, plus a safety ground tab on the side of the plug. A standard SS2-50R RV and marine twist lock setup...

It is a 50 amp for sure.  Look at the 3 pins you do see, there are 2 that point out, on 30 amp, there is only one and it points in.

So do you have 2 twist lock ends and 2 RV plug ends?

Typically your more modern RV with detachable cord will have one twist lock end and one "traditional" end.  The you use a standard RV extension cord.  I did look for a twist lock to twist lock extension cord and never did see one.  There are the Hubbell style connectors used in construction, but I never did get a straight answer if they are compatible or not.

This is the 50 plug on my 5iver

the picture I posted above in the first post is a 50 amp power  - twist lock

To extend your cord another 25-30 feet all you need is a standard 50 amp RV extension cord with a NEMA 14-50 plug on one end and 14-50 receptacle on the other. Many Walmart stores carry them in the RV section,  or Amazon and others have them online.

That is what I should have bought in the 1st place.  Lol

Well, the adapter that Nwcid will work to let you use the cord you have as an extension cord for the OEM cord that came with your RV. Or you could save a few dollars by cutting off the SS2-50R twist-lock plug and replacing it with a 14-50R instead. Just be careful that you get the wires connected to the right terminals.

Kirk - read the *warning* label.  This is typically  a "Marinco"  brand twist lock 50amp connection for an external power cord from an RV to the 50 amp connection at the pedestal of a campground/or RV park.

An easier to read warning label, like the one on my 5th states in LARGE print above the connection:

"This connection for 120/240 volt 3-pole, 4-wire, 60 Hertz  50  AMPERE  SUPPLY"  (the numeral "50" is outlined in a box, capital letters are as printed on the label).

And yes - -  the female only has 3 posts.

It is *NOT* 30 amp!  There are several short adapters available (utilizing the Marinco twist lock 50 amp) to go to a 30 or 15/20 amp supply cord.  (have one connected to my 5er at my home now -  50 amp at the twist lock to three prong 15/20 amp 12 ga cord). They are not cheap!  The Marinco version is usually about $70 for either 30 or 15/20 amp)

However - as someone already stated - the best plan to extend the 50 amp cord is with a 50 amp EXTENSION CORD ! **

It will connect (w/ female)  to the male end of the factory-supplied 50 amp cord, and still have the appropriate (male) 50 amp  plug for the RV park pedestal.

"If* the park does not have a 50 amp connection - use a 50 to 30 adapter to connect to the 30 amp at the pedestal.

** A less expensive option = the above,  50 to 30  (or 15/20) amp adapter on the end of the factory cord,  then use a 30 amp extension cord (WalMart) or a 12 ga extension cord.  (for "basic" power supply only,  *not* A/Cs, etc.)

Pappy is correct. What is pictured is both ends of a 50A RV cord, not an extension cord. The ground wire connection is a metal tab  on the outside of RV end of the cord. That plug and corrsponding receptacle are designed so the ground always engages first.
