Progressive Industries electrical management system with smart surge protection. Model EMS-LCHW50 240v hard wired protection. Used in my motorhome about 10 months. Easy to install and includes manual. Provides RV protection from unknown power posts in campgrounds. Rolling display monitors volts, amps per leg, frequency and any error codes. Great piece of mind when you plug in. Note this is a 50 amp unit that sells new for $290. No low ball offers please. Buyer pays shipping from Tampa Florida.
