Can I use two power cord adapters together

[dee74]

I am in the process of purchasing a new tt that has a 50 amp power cord. I plan on buying a 50 amp to 30 amp adapter much like this one 50 to 30and I already own a 30 amp to 15 amp adapter much like this one 30 to 15 My question I have, is it safe to connect the adapters together or should I purchase a separate 50 amp to 15 amp adapter like this one 50 to 15 ?

great idea, can even get one with surge protector.

Electrically either way will work but generally speaking, the fewer the plug/connector connections the better. My choice would be the 50-15 in the link. A dogbone adapter is also preferable over a puck style.

One thing you should do is always turn the power off before plugging in (either at source end of power cord or inside an RV) otherwise you can end up with pitting on the contacts and dirt buildup leading to overheating. Ensure plug blades are kept clean. Had two 15 amp extension cords go up in smoke in our driveway in a short period to time from failing to shut the power off. Now have a 30A recept. c/w disconnect in our carport.

If you can't turn off the power the outlet as suggested above, plug together 2 of the adapters as your last step (rather than plugging into the wall or the TT last). That way you have a fairly beefy and infrequently used set of connectors that are taking the abuse.

YES

Thanks for the replies. I only need the 15 amp at my home to keep the refrigerator cold. I am fortunate to have a 30 amp outlet at my storage place. My tt really only needs a 30 amp cord but it is prepped to add an additional ac if I would like.

if the RV has a standard Marinco type of male plug on the side I'd just get a female to match, a short length of appropriate sized wire, and put a 15/20 amp male plug on it. then just use any standard extension cord for limited electrical use.

The "dogbone" adaptors are better than the simple plug style. If you're going to be connected long-time to a 15 amp receptacle, I'd get the single adaptor or two dog bone adaptors.

Its likely safe because the camps breakers will not let you overamp their system.
Camps are wired in 2 ways, the old 'spider' system in which each pedestal is individually cabled to the master panel and its breakers there.
Newer camps may have 'loop' cabling which has master breakers sized to the cabling and maximum load at the distribution panel with individual panels controlled by breaker sizing in them. Both are NEC approved.
What you are suggesting to do with multiple connections into a single power point will not give you a higher voltage unless the ped. is wired with L1 & L2, 120v. each. Most 30 amp ped's are L1 only.
You cannot draw a higher amperage from the pedestal than its breakers allow at either location.


Talk to the camp staff and your electrician about using combination devices.

OP is just wanting to plug his 50A TT into a 15A outlet using 2 adapters and his power cord.

Ya, that was blown way out of proportion.
The answer is simply: "Yes, it's fine to use two adapters."

Used a 50A to 30A and then a 30A to 15A plugged into house outlet for 2 weeks while we lived in RV alongside house during closing.
Converter/charger, TV and A/C FAN in use.

Was able to run 15K A/C unit but had to turn off converter and start a/C fan first.

No problem. When in storage I use a 50-30 adapter to a 30-15 adapter. Stays plugged in that way any time it is in storage. Very little load on it of course.

Here is a good article written by DMBRUSS that describes the various RV Adapters along with lots of schematics...

Good info here...
