But since a 50 amp RV protector is three times stronger, it is able to block 3 times more power surges than a 30 amp RV surge protector.

FAQs of 30 amp and 50 amp Surge Protector
Here I will share some frequently asked questions of 30 amp and 50 amp surge protectors.
Can I Plug A 30 Amp RV Into A 50-Amp Power Pedestal?
Yes, you can plug a 30 amp RV into a 50-amp pedestal. The voltage will rise to the maximum the power pedestal is able to provide.
It is always best practice to use the right RV surge proctor for your RV.
Can I Plug A 50 Amp RV Into A 30 Amp Shore Power Pedestal?
No, you can’t plug a 50 amp RV into a 30 amp shore power pedestal. This will not only damage your wiring system, but it may also damage the appliances on your RV.
Also, it can harm your wiring system and even cause a fire in some cases.
Why you cannot do this? The problem here is that the power coming from the pedestal does not have enough juice to power your appliances. The pedestal’s 30 amp rating is split into two legs, with 15 amps each. That means that you cannot use the full 30 amps available in your RV at once.
What is the Solution? The solution here is to have a professional electrician set up a 50 amp pedestal outside your RV.
Instead of this, you should first upgrade your 30 amp RV protector to a 50 amp surge protector.
Will a 50 amp surge protector work on a 30 amp?
No, a 50 amp surge protector will not work on a 30 amp. It can’t be converted. If you do this, it may cause problems with the RV’s wiring system and appliances.
Also, if you use a 50 amp protector on 30 amps, then it will get damaged too.
Can A 50-Amp Surge Protector Plug Into A 30-amp RV Outlet?
No, you can’t plug a 50 amp RV into a 30 amp outlet. Not only will the protector get damaged, but it may also damage the appliances on your RV.
What are the main reasons?
- A 50 amp motorhome has a service cable that is much thicker and heavier than a 30 amp cable.
- The 50 amp outlet has a different shape to prevent a mistake when plugging in the cable.
- The 50 amp outlet is placed with its ground post right below the neutral post. A 30 amp outlet is placed with its ground post right below the hot post. (Fig 1)
- The 50 amp service cable brings many additional wires that do not exist in a 30 amp system (called tandem or quad).
Limitations with 50 Amp to 30 Amp Plug Adapters
If you want to upgrade your 30 amp RV protector with a 50 amp surge protector, then it is wise to know the limitations of these adapters. Here are some limitations that you need to know.
- The 50 amp RV surge protector may be too big for your 30 amp power cord. This can cause problems with plugging it into the outlet.
- The 50 amp RV surge protector should be put on the cord first before being plugged into an outlet.
- The 30 amp RV surge protector usually has a clip that is used to attach it to the power cord. This clip might not work with a 50 amp protector since that one is bigger.
- The 50 amp RV surge protector usually doesn’t have clips since it’s metal and may get damaged using them.
So based on this, I can say that upgrading to a 50 amp RV surge protector is very smart since it will give you more safety and power for your appliances. But there are some limitations with adapters so you need to keep this in mind.
And you should never upgrade your 30 amp RV surge protector to a 50 one using adapters.
