Non-Submersible Grounding Boxes

NonSubmersible1Single phase direct grounding boxes with disconnecting link are used in conjunction with terminations to ground the cable sheath.

Single phase grounding boxes with surge arrestor protection areused in conjunction with terminations to protect the cable sheath from transient voltage build-up and from over-voltages arising from lightning strikes or switching surges.


Three phase direct grounding boxes with disconnecting links are used in conjunction with terminations and splices to ground the cable sheath.
Three phase grounding boxes with surge arrestor protection are used in conjunction with terminations and splices to protect the cable sheath from transient voltage build-up and from over-voltages arising from lightning strikes or switching surges.


Specialty four phase grounding boxes are available for integrating a spare fourth phase. This is convenient in the event of a failure in one of the existing primary phases since it would be already coNonSubmersible002nnected into the existing system bonding scheme.


The boxes provide an easily accessible shield break location that can be used for system testing purposes.


The boxes are suitable for indoor or outdoor environments. They can be mounted vertically or horizontally on a support structure. The cover incorporates a seamless foam-in-place gasket.
