Jeannie you are thinking of a surge PROTECTOR.. Surge Guard is the name of a product... and it works GREAT to protect the RV ... it cuts off all power to the RV if it senses high or low voltage conditions.. protects from surges and does a 2 min polarity check every time you plug in the RV... if the plug head is miss-wired it will not allow power through to the RV

I was using the term you used. "That is why I have the surge guard." Surge Guard (the brand name) makes both surge protectors and EMS units.
Unfortunatly Camping World demands to ship UPS (Unreliable Pathetic and Shi**y) I buy my stuff when I am in the US and the DECLARE it at the boarder. Most often I get it free then under my personal exemption.
