Frequently asked questions

Common questions about HUBBELL-WIEGMANN from 3G Electric.

What is the Hubbell-Wiegmann grounding lug kit WGNDKT used for?

The WGNDKT is an aluminum grounding lug kit designed for use with NEMA 412C enclosures. It includes a grounding bar with 1/4 in holes and assembly hardware. The kit provides a means to connect a ground wire to the enclosure, but the ground wire itself is not included. It is typically used in applications where a reliable grounding path is required for safety and code compliance. Verify compatibility with your specific enclosure model before installation.

What sizes of Hubbell-Wiegmann interior mounting panels are available?

Hubbell-Wiegmann interior mounting panels are available in a range of sizes to fit common enclosure dimensions. Examples include the HW-MP2020A (18.88 in × 18.88 in aluminum), HW-MP1816A (18 in × 16 in aluminum), HW-MP2420CS (23 in × 23 in steel), HW-MP1210A (12 in × 10 in aluminum), and HW-MP1816CS (18 in × 16 in steel). Smaller panels such as a 6.75 in × 5 in steel panel are also offered. Panels are available in aluminum with mill finish or steel with powder-coated finish. Selection depends on enclosure size, component weight, and environmental considerations.

What is the difference between aluminum and steel back panels from Hubbell-Wiegmann?

Aluminum back panels (e.g., HW-MP2020A, HW-MP1816A) have a mill finish and are lightweight, corrosion-resistant, and non-magnetic. Steel back panels (e.g., HW-MP2420CS, HW-MP1816CS) have a powder-coated finish for durability and are magnetic, which can be useful for certain grounding or shielding requirements. Steel panels generally offer higher strength, while aluminum panels are easier to drill and tap. The choice depends on the enclosure environment, component mounting needs, and weight constraints.

Can Hubbell-Wiegmann swing-out panels be used in any enclosure?

The Hubbell-Wiegmann swing-out panel kit (polycarbonate, 9.63 in × 7.63 in) is designed for specific enclosure models that have provisions for a swing-out panel. It is not universal. The panel allows components to be mounted on a hinged surface that swings out for access. Check the enclosure's compatibility and mounting hole pattern before ordering. The polycarbonate construction provides insulation and is suitable for many industrial environments.

What NEMA ratings are associated with Hubbell-Wiegmann enclosures?

Hubbell-Wiegmann enclosures are available with various NEMA ratings, including 1, 3R, 4, 4X, 12, and 13, among others. The rating indicates the level of protection against environmental conditions such as dust, rain, splashing water, and corrosion. For example, NEMA 4X enclosures are constructed from materials like stainless steel or non-metallic composites for corrosion resistance. The grounding lug kit WGNDKT is specified for NEMA 412C enclosures. Always match the enclosure rating to the installation environment.

How do I select the correct Hubbell-Wiegmann back panel for my enclosure?

To select a back panel, first identify the enclosure model and its internal dimensions. The panel's overall height and width must fit within the enclosure's mounting provisions. Consider the material (aluminum or steel) based on weight, corrosion resistance, and grounding needs. The finish (mill or powder-coated) affects durability. Also account for the components to be mounted and their clearance. 3G Electric can assist with cross-referencing part numbers and confirming compatibility with your enclosure.
