Mulberry 30326 – Frequently Asked Questions

1) Can the Mulberry 30326 weatherproof box be used outdoors in a wet location?
Yes. The Mulberry 30326 is a die-cast aluminum enclosure built for outdoor and wet-location wiring, with a powder-coated finish over the casting to resist moisture, UV and general weathering. Typical uses are exterior junction and outlet boxes, outdoor fixtures and receptacles, and surface-mount conduit connections on commercial, industrial and residential buildings.
2) How much wire and how many devices will a 15.3 cubic inch box hold?
The 30326 gives you 15.3 cubic inches of interior volume in a 4 inch by 1-1/2 inch body, which is enough room for splices, a device and conduit connections in one enclosure. Box fill still has to be counted per the NEC for your conductor size, device yokes and grounds, so run the fill calculation against that 15.3 cubic inch figure before you pull wire.
3) I need a deeper or two-gang weatherproof box instead. What else is available?
The Mulberry 30326 is a single 4 inch by 1-1/2 inch body, so it is shallow and single-gang in footprint. For a two-gang opening, the Pass and Seymour WPB Series weatherproof two-gang box is also die-cast aluminum. If you need more depth for a device plus conduit entries, the Pass and Seymour WPBD Series one-gang deep box in gray is the deep option.
4) Does the Mulberry 30326 come with a weatherproof cover or gasket?
The 30326 is the box body only. A weatherproof cover, whether a blank, a flip-lid receptacle cover or an in-use bubble cover, plus its gasket is ordered separately and has to match the device and the box opening. Budget for that cover on the same order so the enclosure is actually rated closed when you leave the job.
5) What is the closest die-cast aluminum weatherproof box to the Mulberry 30326 if I need a two-gang enclosure?
The Mulberry 30326 is a single 4-inch x 1-1/2-inch die-cast aluminum weatherproof box with 15.3 cubic inches of interior volume, so it covers one-gang surface work. For a two-gang opening, the Pass & Seymour WPB Series weatherproof two-gang box is also die-cast aluminum and is built for the same outdoor and wet-location surface-mount use. Match your device count first: two devices will not fit the 30326 footprint.
6) Is the Mulberry 30326 a surface-mount box or does it recess into the wall?
It is a surface-mount enclosure. The 4 inch by 1-1/2 inch profile is sized to sit on the face of a wall, soffit or structure and tie into surface conduit and fittings, which is the normal method for exterior work rather than cutting into the building envelope.
7) Why choose a die-cast aluminum weatherproof box over a plastic or thin steel one?
Die-cast aluminum gives you impact strength and corrosion resistance that lighter-gauge material does not, which matters on exposed walls, loading docks and equipment yards where a box takes hits. The 30326 adds a powder coat over the casting for extra protection against weather and UV. If the run is indoors and dry, you do not need this level of enclosure.
8) Does the Pass and Seymour WPBD deep box look the same as the Mulberry 30326 once it is on the wall?
Not in appearance. The Mulberry 30326 carries a powder-coated finish over its die-cast aluminum body, while the Pass & Seymour WPBD Series one-gang deep box is specified in gray. If you are standardizing the look across a run of exterior boxes on one building, keep to one family rather than mixing the two, even though both are one-gang weatherproof enclosures.
9) Can I use the Pass and Seymour WPB two-gang box as a direct swap for a Mulberry 30326 already mounted?
No. The WPB Series box is a two-gang weatherproof enclosure, so its hub locations and mounting footprint do not line up with the 4-inch x 1-1/2-inch single-gang footprint of the Mulberry 30326. Swapping one in means re-drilling the mounting surface and re-landing the conduit. It is the right choice when the device count changes, not when you are replacing a 30326 in place.
10) What part number do I order for the Mulberry 4 inch weatherproof box?
Order Mulberry 30326. That is the manufacturer part number for the die-cast aluminum weatherproof box in the 4 inch by 1-1/2 inch size, and it is the only configuration in that model.
11) Will a powder-coated aluminum box corrode where it contacts steel conduit or fittings?
The 30326 body is aluminum with a powder coat, which is what handles the weather exposure. Where aluminum meets dissimilar metal in a wet location, use the appropriate fittings and keep the coating intact at the hub so you are not setting up galvanic corrosion at the connection.
