One thing I do - I carry a 50 to 30 adapter. Whenever I am at a 50 spot, I use it instead. I figure it is less often used and will be in better shape.
But by doing this, aren't you removing a layer of protection? The cord on your TT is designed to carry 30 amps, but by plugging it into a 50A breaker, there's the potential that the cord could be exposed to 50 amps of current, causing it to fry.

For instance, what would happen if over the years of pulling the cable in and out of the TT, the wires twisted, creating a minor short somewhere before the attachment to the converter or surge suppressor? (just enough contact to cause some resistance, but not enough to trip a 30A breaker.)
If plugged into a 50A breaker, couldn't the load limit of the wires be exceeded, more easily causing a fire?

I think I would always plug my 30A cable into a 30A (or less) breaker, since that's what the cable is designed for- not 50A.

Edited to add: And who knows. Maybe that's why your plug melted???

Just my 2 cents.

This triggered my memory of "Driveway Camping" in our dealer's parking lot (several times since buying the tt). The shore power was only set up for 50amp. So the service manager had one of the techs give us an a adapter to use. Maybe it's ok to do once in a while if the service people give you one to use overnight? They didn't seem to concerned anyhow. We do keep an adapter with us now, as when traveling, we overnighted a few nights at a cg with only the 50 amp

It doesn't matter how much cord is pulled out. Wire that is properly sized for the load and given clean connections is not going to overheat. Stay with the established brands, Marinco, Hubberd, Camco. Why jeapordize your investment by trying to save a few bucks on some Chinese built piece of c __p?

As an aside, every boat in the world that is wired for 30A shore power has #10 three conductor, usually inclosed in a closed space and often bundled with other wiring and the only problems generated are those caused by burned or corroded connections that once start generating heat should be replaced anyway. 50A cords and wiring are done the same way, only using #6 wire, Anything smaller regardless of how short the run is unacceptable.

The advantage to using the Marinco cord is that the molded rubber is yellow and the plug is easily inspected for burning. If it is a dark color, the end needs to be replaced.

The adapter is only going to use one leg of the 220/50A plug, and the breakers on the converter are going to limit you to 30A, so there's no problem with that.

I thought about what Bill said before, and yes it probably does remove a layer of protection - but the 30 amp breaker and the EMS in the camper should catch most any problems. When my cord melted, I was using a 30 amp - which is when I started to use the 50 amp service. I personally think the risk is minimal compared to the problems I have had with the old 30 amp connectors - but that is just me....my other thought was that if it was really a bad idea - and violated electrical code - they would not be allowed to sell the adapter.

Well, I'm on my way down to the barn right now to pull it all out. Just running the refrigerator but since all I know about Faraday is that he was a moron cop on Boston Blackie, I'm not taking any chances! :dunce:

I am envious of your solar power set-up. It must be quite the system.
