We're in Anacortes, WA for the summer and need somewhere to store our coach. One available space is in a boat storage lot and the power source has a 30amp marine plug (see attached). I can find an adapter on Amazon that will yield a 15amp connection (see attached), but not a 30. Has anyone found a commercially available 30amp adapter?
Thanks in advance,
George
George,
No first hand experience with this one: Power Grip Generator Plug Adapter for RV Power Cord - 30 Amps - 3 Prong... (http://www.etrailer.com/RV-Wiring/Camco/CAM55333.html)
I don't know if a 30 amp generator twist lock is exactly the same as a 30 amp marine.
Not sure about the 'marine adapter' either; whether it's the same as our RVs. Progressive makes a 50 to 30 adapter that we use.
Notice the configuration of the marine female plug. One leg has a "L" connector which is meant to secure the plug since a boat can move around a bit at the dock while plugged in. Brett may be on to something in using a generator plug for it. I will check with the yard and see what they have to say.

The marine is twist lock receptacle. Looks like the nema is L5-30 That says what the volt, amp and configuration is. Once you have that nema number you can mix and match with adapters. The L5-30 is the standard 30A 120V 3 wire twist lock
Found one. I went down to the parking lot where we plan to keep he FT and talked to a guy that had a commercially produced adaptor. He got it on Amazon.

Problem solved.
Thanks for the input.

George, your link is to a 50-amp adapter.
Barry... Sorry, we ended up with a 50amp site for the coach. The place has both 30 and 50 amp sites.
George
I'm going to assume you have a EMS hooked-up. ^.^d
OR, have checked at the female end of the adapter with a voltmeter:
Outer straight to outer straight= 240 VAC
Either outer straight to center straight or center round= 120 VAC
Center straight to center round= 0 VAC
If these aren't your readings, let us know what you find.
Mike... always have one inline. See attached.

I don't know that brand, here's what Progressive has to say:
Brett... Good idea. I contacted the company that makes the adapter and they sent me the attached wiring diagram. Looks OK to me. But I will check. There are three other coaches with this adaptor at the storage site. Also, I have a friend here in Anacortes that is an electrician. I will have him check it!
George
Receptacle posted in first picture is not the same as the adapter
In a 30 amp 120v to 50 amp adapter if you test between the outer blades voltage will be 0 zero since they will be the same phase
That works well with our motorhomes since they have no true 240 V circuits--just two seperate 120 V 50 A circuits.
Yes, there are two different marine 50 amp services-- and the prong configuration is DIFFERENT. One is 50/125, the other 50/125/250. Either will work for George's needs as even the "lessor one", the 50/125 will give 50 amps @125 VAC.. The 240 one is similar to our RV 50 amp service= TWO 50 amps hots @ 125 VAC.
On the sailboat, we carry both styles of adapters.
Scroll down to"Shore Power Cords" see the box on the right showing the different marine configurations.

Finally in storage. The "slip" is not quite level, but not too bad. Turned off the HWH, refrigerator (residential), the inverter, and the salesman's switch. Anything else to turn off when stored with no power? The plug adaptor will not be here until next week. I'll check on the coach frequently. Might even turn the "auto" on for the generator.

Update 6/5/19... The 50/50 amp adapter (see above) arrived and worked perfectly. Checked the voltages and they are as expected. Surge Guard did not object.
