Mulberry 30203 1-Gang Weatherproof Outlet Box with Grounding Lug, Die-Cast Aluminum

The Mulberry 30203 is a 1-Gang Weatherproof Outlet Box built from powder-coated die-cast aluminum, engineered to house wiring devices in exposed or outdoor electrical runs where moisture, corrosion, and impact resistance matter most. This box includes an integral grounding lug for a secure equipment ground connection and carries a 2.750-I dimension for consistent fit within standard weatherproof device assemblies and covers. It is available in Bronze and White finishes, giving electricians a matching option for a range of exterior surfaces while keeping the same rugged die-cast aluminum body and integral grounding lug across both finish options. Mulberry engineers this box to mount standard single-gang wiring devices, such as receptacles or switches, while keeping the internal wiring connections sealed against rain, humidity, and general jobsite weathering.

Key Features

  • Configuration: 1-Gang layout accommodates a single standard-size wiring device for receptacles or switches.
  • Durable Construction: Powder-coated die-cast aluminum body resists corrosion and impact better than lightweight stamped-steel alternatives.
  • Weatherproof Design: Outlet box construction is built for exposed, outdoor, and wet-location mounting of wiring devices.
  • Grounding Lug: Integral lug provides a dedicated point for equipment grounding connections, simplifying bonding at the box.
  • Finish Options: Available in Bronze and White powder-coated finishes, letting installers match the box to the surrounding exterior surface.
  • Dimension: 2.750-I sizing keeps the box compatible with standard single-gang weatherproof device covers and assemblies.
  • Material Advantage: Die-cast aluminum construction offers a favorable strength-to-weight ratio compared to heavier cast alternatives, easing handling during installation.

Why Mulberry?

Mulberry builds the 30203 outlet box from powder-coated die-cast aluminum specifically so it can stand up to the corrosion and physical stress that outdoor electrical boxes face over time. The integral grounding lug and weatherproof 1-Gang configuration reflect a design focused on dependable, code-conscious installations for professional electricians, and the Bronze and White finish options let installers keep a consistent look across a building exterior. Choosing Mulberry electrical boxes means choosing rugged materials, a protective powder-coated finish, and practical grounding features built for real-world jobsite conditions where weather exposure is a constant concern.

Mulberry 30203W – Frequently Asked Questions

1) Can the Mulberry 30203 weatherproof outlet box be used outdoors in a wet location?
That is what the 30203 is built for. It is a weatherproof 1-gang outlet box in die-cast aluminum with a powder-coated finish, intended for exposed outdoor and wet-location mounting of wiring devices. To keep it weatherproof in service you still pair it with a weatherproof device cover and seal the conduit entries.
2) How many devices will the Mulberry 30203 box hold?
One. It is a 1-gang box sized for a single standard wiring device, so a single duplex receptacle or one switch. For two devices side by side you would need a 2-gang box such as the Thomas and Betts 2IH3-1 Red-Dot 2-gang conduit outlet box.
3) Will a standard single-gang weatherproof cover fit the Mulberry 30203?
Yes. The 30203 carries a 2.750-I dimension, which keeps it in line with standard single-gang weatherproof device covers and assemblies, so a conventional 1-gang flip-lid or in-use cover mounts to it.
4) Can I use the Mulberry 30203 outlet box in a hazardous or classified location?
The Mulberry 30203 is a weatherproof die-cast aluminum outlet box for exposed and wet-location wiring devices; it is built for weather exposure, not for classified areas. Where the drawing calls for an explosionproof enclosure, the Appleton GRJ Series and GRJS Series conduit outlet boxes are explosionproof malleable iron bodies, and the Appleton GRT75 is a malleable iron round conduit outlet box in the same family of cast fittings.
5) What is the closest alternative to the Mulberry 30203 weatherproof outlet box for a 2-gang exterior device?
The Mulberry 30203 is a 1-gang die-cast aluminum weatherproof outlet box, so it holds a single standard wiring device. For a two-device exterior opening, the Thomas & Betts 2IH3-1 Red-Dot is a 2-gang conduit outlet box with three 1/2 inch hubs, sold in a pack of 100. That gives you the second gang in the same exposed-conduit style of enclosure.
6) Does the Mulberry 30203 outlet box have a place to land an equipment ground?
Yes, there is an integral grounding lug cast into the box, so you get a dedicated point to land the equipment grounding conductor and bond the metal enclosure without adding a separate ground screw or clip.
7) Aluminum or steel box for an exterior wall - which should I use?
For an exposed exterior device, the 30203's powder-coated die-cast aluminum resists corrosion and impact better than lightweight stamped steel, and it is lighter to handle than heavier cast bodies. Welded steel square boxes like the Orbit 4SDB deep box or the RACO 229 BOX-LOC box are made for concealed interior or in-wall work, not exposed weather. Hazardous locations are a separate case and call for an explosionproof malleable iron box such as the Appleton GRJ or GRJS series.
8) Is a weatherproof cover included with the Mulberry 30203 outlet box?
No. The 30203 is the box with its grounding lug only. You order the wiring device and a single-gang weatherproof cover separately, plus conduit fittings or connectors for the entries.
9) What should I use instead of the Mulberry 30203 for an interior wall rough-in?
The Mulberry 30203 is a powder-coated die-cast aluminum weatherproof box intended for exposed and outdoor runs. For concealed interior work, the Cantex EZ Series is a PVC multi-gang residential outlet box, and the RACO 229 BOX-LOC is a 4 inch square welded steel box with AC/MC/flex clamps for cable-wired interior framing. The Orbit 4SDB is a welded steel square deep box with 1 inch knockouts if you need the extra cubic capacity inside.
10) How does the Mulberry 30203 die-cast aluminum box differ from a malleable iron conduit box?
Both are cast enclosures for exposed conduit work. The Mulberry 30203 uses a powder-coated die-cast aluminum body with an integral grounding lug in a 1-gang configuration, which keeps it lighter in the hand on a ladder. The Appleton GRJS Series and GRT75 are malleable iron conduit outlet boxes, a heavier casting typically specified where the enclosure also has to satisfy explosionproof requirements.
11) Is the Mulberry 30203 a substitute for a range and dryer box?
No. The Mulberry 30203 is a 1-gang weatherproof box sized for a standard single-gang receptacle or switch. A dedicated appliance outlet is a different enclosure: the Pass and Seymour P242RRD is a thermoplastic range and dryer box built for that specific device. The two are not interchangeable.
12) I need to match existing boxes across a building exterior - can I standardize on the Mulberry 30203?
It works well for that. The same 30203 box is offered in White and Bronze, so you can keep one part number and one body style across a property and just pick the finish per elevation. Both finishes carry the identical die-cast aluminum construction and grounding lug, so maintenance stocks one spare for all of them.
13) If I need more wiring volume than the Mulberry 30203 1-gang box, what else can I look at?
The Mulberry 30203 is a 1-gang die-cast aluminum box carrying a 2.750-I dimension so it mates with standard single-gang weatherproof covers. Where splice volume is the constraint, the RACO 232MS STAB-iT is a 4 inch square welded box 2-1/8 inches deep rated 600V, and the Orbit 4SDB is a square deep welded steel box with 1 inch knockouts. Both are larger square bodies rather than single-gang weatherproof shells, so your cover and device plate selection changes with them.
