Red Dot B37D20G – Frequently Asked Questions
1) How many 3/4 inch hubs does the Red Dot B37D20G three-gang weatherproof box have, and where are they?
The B37D20G is a three-gang Red Dot weatherproof box with seven 3/4 inch threaded hubs. Seven openings gives you feed, through-wiring and branch runs off the same box without adding a condulet, and any hubs you do not use get closed off with 3/4 inch plugs, which are ordered separately. The box is sold each.
2) Can a Red Dot B37D20G weatherproof box be used outdoors in a wet location?
Yes. The Dry-tite box line protects wiring devices, switches, electronic components and terminal blocks in dry, damp and wet locations, so an exterior wall, a loading dock or a wash-down area is within its intended use. The weather seal depends on the cover and gasket you pair with it, which are separate items.
3) Is this Red Dot three-gang weatherproof box UL and CSA listed for an inspected job?
Yes, it carries UL E2969 and CSA 703005, so it satisfies both US and Canadian listing requirements on a permitted installation.
4) Does the Red Dot B37D20G come with a cover?
No. The B37D20G is the box body only, sold each with its seven 3/4 inch hubs. You order the three-gang cover and gasket for the devices you are installing separately, plus closure plugs for any unused hubs.
5) Will three standard devices fit in a 54.8 cubic inch weatherproof box?
The B37D20G has 54.8 cubic inches of volume across its three gangs, which is what you work from when you count conductors for box fill. Three devices plus the conductors, grounds and clamps feeding seven 3/4 inch hubs is a tight count, so total your fill before you commit, especially if you are through-wiring multiple circuits.
6) Is the Red Dot B37D20G box aluminum or plastic, and will it corrode near the coast?
It is cast aluminum, specifically alloy A380, and the hardware is certified zinc alloy with stainless steel springs for increased corrosion resistance. That combination is what makes it suitable for exposed exterior and damp industrial work rather than a plastic PVC box.
7) Do I need conduit fittings to connect EMT or rigid to this box?
The hubs are 3/4 inch threaded, so rigid or IMC threads straight in. EMT, PVC or flexible conduit needs a 3/4 inch male-threaded adapter or connector to land in the hub. There are seven hubs, so plan a fitting for each run you are bringing in and plugs for the rest.
8) What color is the B37D20G box, and will it match other Red Dot gray weatherproof boxes on the building?
It is the standard gray aluminum finish, listed as silver, which is the same look as the rest of the Red Dot weatherproof box family. For a facility standardizing exterior device boxes, it reads consistently alongside other gray cast aluminum boxes without painting.
