What kind of shore power outlets does Fontana have?

I remember going there last year and not having the correct connector - IIRC they've got the regular 120V "normal" 20A plugs, and then I think a NEMA 14-50 (50A RV connector) plug as well? I've got a NEMA L14-30 connector to plug into my generator but I don't have a 14-50 adapter for it. My trailer pulls more juice than the 120V-20A socket will be able to provide when it's running the heater as well as all the normal stuff.

NEMA L14-30 (what I have):


NEMA 14-50 (can anyone confirm this is actually what's at Fontana?):

 

When I was at Fontana last year I plugged my motorhome into a standard 50amp plug like the one in your picture.

 

Awesome, thanks. I'll build an adapter for that.

For the effort to build one, the above adapter is already ready to go for $17.

 

Except that's not what he needs.

He has a L14-30, which is a 120/240V 30A connector, much like an electric dryer plug. (Its a twist-lock version of the 14-30 dryer plug.) If he adapts to the 120V 30A RV type plug then he only gets 30A @ 120 V instead of 60A@120V (30A x 2). It may or may not work for him, and definitely won't if he has anything that needs 240V.

He can go to a box store, get a 14-50 range cord, and then add a female L14-30 connector on the loose ends.

 

My bad. That's going the wrong direction. My RV has the 50 amp plug that has to be converted to 30 sometimes.

 

From my experience 50a RV plug are 240v 2-live/1 neutral/1 ground.
The 30a RV 3prong are 110v. Only 1 live.

The 30a Genny plug you posted in first post should be 240/ 2 live/1N/1g

Your RV or trailer should be female. I've never seen premade adapters with male on both ends ..... Shock hazard..

Unless you need male on both ends buying a premade adapter is easiest.

I've got 50a RV to 2 -30- RV and adapters to split it down to 3 120-15a I've bought off amazon. They have almost every possible adapter.

 

I ordered this a few hours ago - https://www.amazon.com/gp/product/B076ZTWL4K/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1

I get the right thing?

 

You'll need this one unless you need male ends on both ends.

Lowe's has the ends and 4/10 cable. The ends alone will cost you 20-$40

 

Is the plug on trlr or RV male or female?

 

Plug on the trailer is male, and I attach the female end of my cord to it. I have a regular M/F L14-30 extension cord that plugs its male end into my generator (EU7000, has the topmost-pic socket in this thread). The generator provides 240V 30A

 

Yes that adapter should work great

 

Yes.

 

Good luck in Fontucky, @tophyr
