Getting 50A from a 30A+20A post

[FTWingRiders]

Hello all,
Loving the new 325SRX, what a RV!! Question about getting extra juice for the 50 A tho.. The campground we've been going to for years has both a 30A and a 20A with separate circuit breakers in their post. As this is my first 50A camper, I found this little adapter at CW..

Just wondering if anyone else uses this to get the full 50A for the RV? Good idea, or bad? I've got the progressive 50A surge protector just in case.

Tried searching first for the answer, sorry if this has been discussed before!!

That adapter allows for a little extra electricity, but you won't get the "full 50 Amp service" that you get using the 50 Amp plugin. The RV plug when connected to a 50 Amp socket provides 50 Amps on each leg (total 100 Amps)

When you use the adapter and plug into the 30 amp and the 20 amp plugs, you get just that: 30 amps on one of the legs and 20 amps on the other leg. Yes, that's a total of 50 amps, but it does not provide the 100 amps that you get using the 50 amp campground supply.

I have a similar product and it works just fine.... AS LONG AS the 20 amp circuit available to you is NOT a GFCI outlet (most are).... If it is a GFCI outlet (or breaker), it will trip.

The function of this device depends on how the power pedestal is wired internally. If the 30A and 20A outlets are on different 120V legs, then you will get the result JRTJH describes, which is usually adequate and may appear to "work just fine", even with 240V appliances, as long as you don't trip either breaker by drawing too much.

But if the 20A and 30A outlets share the same leg, then your 240V devices will not work at all.

I have yet to see a Keystone RV with a 240 volt device in it. Everything in the Keystone line uses 120 volt AC or 12 volt DC. Where have you found 240 volt appliances in Keystone products?

Thanks for all the replies! Looks like another cord to add, but if it will allow a little extra juice when you can't get a 50A site, definitely worth it. I'm at my favorite campground 2 weeks every year, and with only 30A max,with the 20A outlet too, I'll feel better when the AC is in full blast mode.

Don't some Keystones include a clothes dryer? Are you telling me it's not 240V?

I purchased one at General RV for about 1/2 the price as the one your showing. As far as it's performance... It's a little better than just 30A but it's not anywere near a 50A hookup performance.

Diugo -

Here to tell ya, go on out to your friendly CW and peruse, the dryer is 120VAC. I know in some high end fivers and some dieselpushers, there are 240VAC appliances including dryer and AC. But like John said, not in Keystone.
