MK-2551

The MK-2551A/U is an alternative grounding system designed primarily for use in tactical operations for quick installation and tear-down. It can be easily installed and removed in situations where using conventional grounding rods would not be possible. It does not replace the ground rod, but is an option for use as situations or circumstances may warrant. The MK-2551A/U shall not be used as a permanent grounding system.

The MK-2551A/U provides a safe path to discharge lightning, enhancing safety of personnel and equipment. It also helps to control noise in signal circuits. The total resistance-to-ground ratio is equal to or better than that of a single ground rod, allowing the equipment to better survive a lightning strike than a single ground rod.

Usage

NOTE: Use of the MK-2551 is not authorized for permanent or semi-permanent installations. Every day the MK-2551 is deployed, check the main wire and stakes for looseness. If the wire or stakes are loose, they must be reinstalled to improve the performance. Deployment of the MK-2551 in applications that have high vehicle or personnel traffic in the vicinity may result in the necessity of more frequent checks.
