Favorite

Appleton™ EGC static ground indicators connect to tanker trucks to provide a positive ground prior to the dispensing of flammable materials. A positive ground safeguards trucks, railcars and loading racks from the accumulation of static charge during transfer operations.
Features
  • Two wire positive ground indicator system renders the pumping system inoperable without a positive ground.

  • Intrinsically safe ground detecting circuitry.

  • Supplied standard with two LED indicator lights. Red indicates unit is on but without a positive ground. Green indicates positive ground.

  • Supplied with a 7.6 meter (25 foot) cord and heavy duty self-release clamp.

  • Release of the ground clamp opens the contacts, stops the product flow and is indicated by the red LED pilot light.

  • Circuitry will control a pump, valve or indicating device such as light or audible warning device.

  • Provided with internal ground lug.

  • If any electrical connections fail (either in the enclosure or at the ground rod) the red indicator light will be on and the unit will not operate and switch to green; until the problem is solved.

  • An optional retractable reel is available to raise and lower static ground cable. Allows cable and clamp to hang free when not in use. The clamp should not be in contact with ground when not in use. The retractable reel is supplied with 7.6 meter (25 foot) of nylon covered steel cable and cable securing clamp.
