Y-split adapter to get more power at a 30-amp site

[Bob K4TAX]

Our TT has a 30A service. I carry a 50A to 30A adapter. But we still have only 30A, not 50A. The main breaker inside the trailer is 30A which is the limiting factor.

I also carry a 20A to 30A adapter. With this, I only have 20A which is limited by the breaker on the power post.

There is no free lunch.

In a service you can only have 1 neutral. As many circuits as you like, just one neutral. Every circuit uses that 1 neutral. With the neutral and ground lug bars connecting at one point, I'm thinking the sensitivity of the GFI is picking up the introduction of a new neutral as a dead short to ground. A regular plug would probably work, but then....

I'm 50 amp so never needed or tried one of these

So how do you deal with smaller campgrounds that only have 30A service?

My rig is 50Amp, all electric, 3 roof acs, resi fridge, induction cooktop etc. I don't use washer/dryer or ACs when on 30A, everything else (as long as you don't run at once) works without a problem. That's not even a hard rule, just two weeks ago I was in that position and it was getting hot. I turned on one AC and nothing tripped. I think you just need to be mindful of what you're going to use.
Yes you won't be able to use all 3 ACs, run a load of laundry, cook and use the oven at once, honestly I don't even know if I'd be able to do that with 50A.

Not trying to sound flip, but you use what you've got. I've seen many people try to rig something up and later regret it.
Also, just my observations, my wife and I try to book parks that have 50 amp. Some don't, but in all our trekking around the country I haven't yet not been able to find one that suited our needs.
Just be careful. I just want to throw this into the conversation.
Get yourself a multimeter and always check your pedestal. Many of the older parks aren't up to code and nothing will cook your rig quicker than an open ground. I've seen it a few times. A meter can save your rig

Yes we've come to the conclusion that, as Rich put it, we don't want to 'displease the electronics' on an expensive rv. We saw many thoughtful comments about safety, good explanations from knowledgeable folks. Thank you all - we've decided to bite the bullet and look into soft-start (on sale right now). AND we're trying to stick to 50-amp campgrounds.

The 800+ mostly positive reviews on the etrailer link above reveal that this does work with caveats as described in the reviews. I certainly wouldn’t use it without an EMS checking for proper wiring and electrical conditions before allowing power Into RV.
