Your RV Questions Answered! part 2

Welcome back to Two-Minute Tech Tip Tuesday, brought to you by the National RV Training Academy (NRVTA)—the largest hands-on RV training school in America! Before we dive in, don’t forget to subscribe to our channel so you never miss a tech tip that can save you time, money, and headaches.

This week, Todd is answering some great viewer questions about plugging your RV into lower-amperage power sources—like a standard household outlet—and using EMS surge protectors correctly when switching between 50-amp and 30-amp services.

Question 1: Can I Plug My 50-Amp RV into a 120V Household Outlet?

This question comes from Kevin, who just purchased his first RV (congrats, Kevin!) and asked:

“I just bought a camper that has a 50-amp hookup. Until I have 50-amp service installed at my house, can I step it down and plug my camper into a 120-volt outlet?”

The Answer:

Yes—you absolutely can plug your 50-amp RV into a regular 120V household outlet using the proper adapter (often referred to as a “dog bone” adapter). But there’s a big caveat…

You Must Reduce Your Electrical Demand

When you reduce your power supply from 50 amps down to 15 amps (a standard household outlet), you must also reduce the demand inside your RV. Here’s what that means:

What You Can Do:

• Turn on the lights
• Use your converter to charge your batteries
• Possibly run your refrigerator (especially if it’s energy-efficient)

What You Cannot Do:

• Run your air conditioner—it requires far more power
• Use the microwave (at least not reliably)
• Power multiple heavy-draw devices at once

So, while this setup is fine for basic power needs—like keeping the lights on and maintaining your batteries—it’s not suitable for full functionality or comfort.

Question 2: Can I Use My 50-Amp EMS Surge Protector on a 30-Amp Pedestal?

This next question comes from Scott, who asked:

“I have a 50-amp RV and a 50-amp EMS surge protector. If I go to a 30-amp site, is it okay to use a 30-to-50 dog bone to plug into my EMS and then into my RV?”

The Answer:

Yes, you can safely do this with most EMS (Electrical Management System) surge protectors. Here’s how it works:

• Using a 30-to-50 amp dog bone adapter, you can connect your 50-amp surge protector to a 30-amp power pedestal.
• Your EMS will still function, though it may show different readings:
  • Leg 1 will have voltage.
  • Leg 2 may show zero or the same voltage (depending on how it’s wired).

This setup won’t hurt your EMS or RV, but again—you’re limited by the power capacity of the source.

Know Your Limits:

• A 50-amp RV has access to 12,000 watts of power (50A x 240V).
• A 30-amp pedestal only gives you 3,600 watts (30A x 120V).

So if you’re plugging into a 30-amp source with your 50-amp RV, you’ll need to manage your load carefully to avoid tripping breakers.

Final Thoughts from Todd

Both of these questions highlight a common theme in RV electrical setups: Yes, you can plug in. But can you power everything? Not always.

Managing your power needs—and understanding what your RV and power source can handle—is crucial for safe and efficient travel.
