Which Leg Does the 50A to 15A SmartPlug RV Power Cord Adapter Supply Power to?

Question:

Re: Smartplug 50 amp to 15 amp. If the plug only supplies one leg, how do I know if the 12 volt refrigerator is on the leg that it works with? How I can I find this out. The plug will not benefit me if the fridge doesnt work while Im parked at a friends house. Thank you for your help. Cely Holcombe 2023 Airstream 30FBQ with Office.

Hey Cecilia, thanks for reaching out!

The SmartPlug RV Power Cord Adapter # SM93VR will power both legs according to my contact at SmartPlug. You just need to make sure you limit yourself to the 15A rating of the adapter as it won't be able to supply the full 50A power that a standard 50A plug would.

Does that sound like it will work for your setup?

Yes! I'm a girl new to this type of wiring...haha I had read that 2 people could not run their 12 volt fridge which had me concerned. Now think it was pilot error. I ordered. Yal are such a great team and so helpful. USPS sucks...been over a week and still haven't received my order from yal. Not your problem...USPS problem. I'll pay more next time to get item quicker.
