Thomas & Betts IH5-LM Device Box

Two hub sizes: 1/2 inch (model IH5-1-LM) and 3/4 inch (model IH5-2-LM). Pick the one that matches the conduit you are running into the box; there is no reducing bushing included, so order the hub that fits the trade size on the job.

The IH5-LM gives you 17 cubic inches of wiring volume in a single-gang box, and the cubic content is cast right on the box so an inspector can read it. Using the NEC volume allowances, 17 cubic inches supports eight 14 AWG conductors (2.00 cu in each) or seven 12 AWG (2.25 cu in each) before you count device and clamp deductions.

On its own, no. The IH5-LM is rain tight only when it is paired with the appropriate Red Dot cover, so the cover is part of the weather seal and has to be ordered with it. The box itself is machined with clean cover edges to seat the gasket, and it is listed for dry, damp and wet locations in that combination.

No. The IH5-LM is a UL listed die cast aluminum device box intended for dry, damp and wet locations, and it is rain tight when paired with the appropriate Red Dot covers. For a classified area you need an explosionproof enclosure instead, such as the Appleton GRJ series explosionproof conduit outlet box in malleable iron, the Appleton GRJS universal explosionproof conduit outlet box, or for a round body the Appleton GRT75 malleable iron round conduit outlet box.

The Mulberry Royal Mountie weatherproof outlet box is the nearest match in construction and capacity class: it is a die-cast aluminum, 1-gang weatherproof box, the same material and gang count as the IH5-LM, which is die cast aluminum and one gang with a 17 cubic inch wiring volume. The IH5-LM is ordered by threaded hub size in 1/2 inch (IH5-1-LM) or 3/4 inch (IH5-2-LM), so match the hub to the conduit trade size you are landing.

It is die cast A380 aluminum with certified zinc alloy hardware and stainless steel springs, which is the combination that keeps the box from seizing or blooming in damp and coastal air. Finish is powder coat in silver. For genuinely corrosive or classified atmospheres you want a different animal, such as the Appleton GRJ Series explosionproof malleable iron outlet box.

The casting works out to 4 9/16 by 2 13/16 by 2 inches on the main body, with a 3 13/16 inch dimension across the mounting lug span, 3 1/2 and 3 1/4 inch intermediate dimensions, and 1 7/8 and 1 1/2 inch hub and depth references. The 2 inch depth is the number that usually decides it, since a deep device plus a backbox clamp eats that fast.

Yes. The IH5-LM has cast mounting lugs that accept a variety of mounting methods, so it goes onto masonry, strut or a pole bracket without an adapter plate. The device mounting plates are factory fastened in the casting, which is what keeps a receptacle from going loose later.

Yes, it carries UL certification, and the UL marking is cast into the box along with the cubic content so an inspector can verify it on the wall without paperwork.

The IH5-LM is the die cast aluminum route: rugged casting with machined faces, built for exposed industrial and exterior work where the box takes abuse. If you are doing residential rough-in behind finished wall and want multi-gang in nonmetallic, the Cantex EZ Series PVC multi-gang residential outlet box is the other approach. For a one-gang die cast weatherproof alternative, the Mulberry Royal Mountie is the comparable.

It is not the right box for that. The IH5-LM is a one-gang 17 cubic inch device box, too small for the conductors and the receptacle a range or dryer circuit needs. Use a purpose-built unit like the Pass & Seymour P242RRD range and dryer box instead.

The IH5-LM is a cast metal, hub-fed box sized at 4 9/16 by 2 13/16 by 2 inches with a 17 cubic inch volume, built as a rugged device and junction enclosure. For stud-bay residential rough-in where nonmetallic cable is used, the Cantex EZ Box series PVC multi-gang residential outlet box is the type normally specified, and it offers multi-gang configurations where the IH5-LM is one gang only.

No, they serve different purposes. The Pass & Seymour P242RRD is a thermoplastic range and dryer box built around a single large appliance receptacle outlet. The IH5-LM is a one-gang die cast aluminum device and junction box with a 17 cubic inch wiring chamber, threaded hubs in 1/2 or 3/4 inch, and a powder-coated finish for use in dry, damp and wet locations with the appropriate covers.

The IH5-LM uses alloy A380 aluminum with certified zinc alloy and stainless steel springs for corrosion resistance, which suits general dry, damp and wet location device work. Where the specification calls for a malleable iron body, the Appleton GRJ series and the round Appleton GRT75 are malleable iron conduit outlet boxes, and the GRJ and GRJS are explosionproof designs for classified areas.

Yes. Besides holding a wiring device or switch, it works as a junction box for branch conduits and as an accessible wiring chamber for pulling conductors and making splices. The cast and machined interior surfaces are smooth so pulls do not nick insulation. Just hold to the 17 cubic inch fill.

Sold each, one box per inner pack, with 25 to a standard outer carton. Handy if you are standardizing a building and want to buy a full case per crew.
