Surges and overvoltage
The eGauge is rated for overvoltage CAT III, covering installation on main distribution panels. Devices that experience a CAT III or lower surge may have internal, non-user replaceable fuses blown. Surges exceeding CAT III limits may not be repairable. Contact eGauge support at firstname.lastname@example.org to set up an inspection RMA if your device no longer powers on due to surge or overvoltage. Note that damage caused by overvoltage is not covered under warranty.
