Helpful Expert Reply:
You will always use a surge protector matched to the TT's rating of 30 amps. I recommend the Power Watchdog the 30 amp Surge Protector with Bluetooth # HU97FR. You can use the free smartphone app to monitor your system and get notified if low or high voltage is detected. If you aren't using a surge protector, you're taking a big risk. While spikes caused by lightning can damage your electrical system and appliances, there are common electrical issues that can be just as dangerous.
If you are at a 50 amp service only site, you will need plug your RV's power cord into the surge protector and then plug the surge protector into a 30 amp to 50 amp adapter cord like the Mighty Cord RV Power Cord Adapter # A10-5030FHVP.
