hvGrid-tech’s Type N weatherproof link box is IP66/NEMA 4X rated and is intended for use at above ground locations, outdoors or indoors. The boxes can be mounted vertically or horizontally.
All bond lead entrances are IP68/NEMA 6P rated and are sized to the specific dimensions of the insulated single conductor bond leads.
The hinged cover is secured with stainless steel fasteners and incorporates a seamless compressible gasket with a resilient cellular structure. The hinged cover may be supplied with a clear window to facilitate inspection without unsealing the enclosure. Link fasteners are readily accessible when the cover is opened to permit measurement of contact resistance as well as link removal and replacement for jacket integrity testing.
