Can 50 Amp Surge Protector Be Used with 30 Amp Power Supply

Published 02/17/2017

Question:

My RV 2016 Thor Windsport has a 50 amp power cable that connects to an external 50 amp supply. Some RV parks only offer 30 amp service. Is there any problem with a 50 amp surge protector working properly when connected to a 30 amp supply?

You can use a 50 amp surge protector on your 30 amp service but I would offer a bit of caution. If any of your appliances or items are rated at 30 amps and something happened that caused them to draw more power, the 50 amp surge protector would not trigger and you could suffer damage to those items.

If you decide to use the 50 amp surge protector I recommend making sure everything is in good working order, but as I stated, if there were a problem it may cause damage because the circuit was not broken.
