The Surge Guard 34951 provides total electrical protection for your 50-amp RV, including protection against wiring issues; reverse polarity, open neutral and open ground. Also protects against low/high voltage, low/high frequency and elevated ground line current. Includes patent-pending Load Side Open Neutral Protection that detects and protects your RV from the catastrophic results of an open neutral in a 50-amp RV electrical system. Ten-second start-up sequence and 128 second fault delay sequence protect compressor motors against damage. Works with Surge Guard Wireless LCD Display (sold separately). A security ring on the cord lets you lock the Surge Guard to prevent theft.
