Electrical Enclosure Stands
Electrical enclosures are designed to house industrial components and to protect them from the surrounding environment. They are also designed to protect operators from electric shock. Enclosures come in wall-mount, floor-mount (with legs) and freestanding (enclosure extends to the floor). When selecting freestanding enclosures, there are several enclosure bases to consider: floor stands, leg and casters and pedestals. Enclosure floor stands can easily be installed on most freestanding or wall-mount enclosures for floor mounting or to add additional height.
Hoffman Floor Stand Kits are easily installed on most Hoffman wall-mount enclosures and can be used to elevate Hoffman free-stand enclosures. They maintain UL/CSA Type 4, 4X (stainless steel only) and Type 12 when properly installed on Hoffman Type 4 and Type 12 enclosures. The stainless steel floor stand is available in Type 316 and Type 304 and the 12 gauge steel floor stand has a painted finish. Each kit includes two stands. Two sets of floor stands are recommended for enclosures larger than double door free-stand enclosures.

Hoffman PROLINE G2 Floor Stand Kits mount depth-wise on the PROLINE G2 enclosures, securing both through the corner blocks and the frame drain holes. The 12 gauge painted steel floor stand kits are used to elevate the enclosure off the ground by approximately 1 ft.
Maintaining NEMA 4 Rating When Making Enclosure Penetrations
Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure. This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure. There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure. If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
