Thomas & Betts IHD3-1 Device Boxes, Covers & Accessories, 100 Pack

One gang, 24.8 cubic inches of volume. That single-gang opening takes one switch or receptacle, and the 24.8 cu in is the number an inspector uses for conductor fill calculations. The cubic content is cast into the box along with the UL marking, so the capacity can be read on site without the spec sheet.

No. The IHD3-1 is a die cast aluminum device box that is rain tight when used with appropriate Red Dot covers, which addresses dry, damp and wet locations rather than classified areas. For a classified location you need an explosionproof enclosure such as the Appleton GRJ series or GRJS series universal conduit outlet boxes in malleable iron, or the Appleton GRT75 malleable iron round conduit outlet box. Those are built as explosionproof conduit outlet bodies and are not interchangeable with a weatherproof device box.

The Mulberry Royal Mountie P473899 is the nearest match in material and configuration: it is a die-cast aluminum weatherproof outlet box in a 1-gang arrangement, the same material and gang count as the IHD3-1, which is die cast aluminum and single-gang. Confirm hub size against your conduit run before swapping, since the IHD3-1 carries its own hub sizing and the two series use different cover families.

The published dimensional references for the IHD3-1 are 4-9/16, 2-13/16 and 2-5/8 inches, with further dimensions of 3-13/16, 3-1/2, 3-1/4, 1-7/8 and 1-1/2 inches covering the mounting lug and cover-face layout. Map those against the drawing dimension letters when you are fitting it into a tight chase or lining up with existing boxes on the same wall.

Corrosion resistance is the point of the build. The IHD3-1 body is die cast Alloy A380 aluminum with a powder-coated silver finish, and the assembly uses certified zinc alloy parts and stainless steel springs for added corrosion resistance. It is also RoHS compliant. For a classified hazardous area it is the wrong box; a malleable iron explosionproof outlet box such as the Appleton GRJ Series is what that spec calls for.

It casts in mounting lugs that accept a variety of mounting methods, so it can be surface fastened rather than needing a bracket or stud ears. The device mounting plates inside are securely fastened as part of the box, which is what keeps a device from loosening and generating a call back. Each box weighs 0.75 lbs.

Yes. Besides holding a wiring device, the IHD3-1 serves as a junction box for branch conduits, and its accessible wiring chamber gives you room to pull conductors, make splices, and later maintain or change out a system without opening the raceway. Cast and machined interior surfaces are smooth enough for safer wire pulling.

The IHD3-1 is a die cast aluminum, one gang box built as a rugged enclosure for devices in dry, damp and wet locations with the right cover. A nonmetallic alternative like the Cantex EZ Series PVC multi-gang residential box suits interior residential rough-in and multiple gangs; the Pass & Seymour P242RRD is a thermoplastic range and dryer box for that specific appliance outlet. Pick the cast box where impact, corrosion, or conduit entry into a surface-mounted enclosure is the concern. For a comparable die-cast aluminum one-gang weatherproof box from another brand, there is the Mulberry Royal Mountie.

For interior residential rough-in, the Cantex EZ Box series is a PVC multi-gang residential outlet box, a nonmetallic option available in multiple gang widths. The IHD3-1 is a different build: die cast aluminum, single-gang, with a 24.8 cubic inch volume, intended as a junction box for branch conduits and for protecting devices in dry, damp and wet locations. Choose the PVC box for nonmetallic residential wiring and the aluminum box where you are landing conduit hubs.

That is a different box. A range or dryer outlet needs a box sized and configured for the large appliance receptacle, such as the Pass and Seymour P242RRD range and dryer box in thermoplastic. The IHD3-1 is a one-gang die cast aluminum device box with 24.8 cubic inches of volume, suited to standard wiring devices, switches, electronic components and terminal blocks.
