Bridgeport Fittings 630-DC2 – Frequently Asked Questions

1) What size knockout does the Bridgeport 630-DC2 duplex connector need?
The 630-DC2 goes into a 1/2 inch knockout. That is the point of the duplex design: two runs of 3/8 inch flexible metal conduit or armored cable land in a single 1/2 inch KO instead of taking up two openings on the box or panel.
2) Will this Bridgeport duplex connector accept 12/2 or 10/3 armored cable?
Yes. The strap type duplex connector is rated for 14/2 through 10/3 armored cable, covering an outside diameter range of .430 to .610 inches, so 12/2 sits comfortably inside that window. It also takes 3/8 inch trade size flexible metal conduit.
3) Can I run two separate MC cable whips into one box opening with this fitting?
That is exactly what it does. One 630-DC2 takes two lengths of flex or armored cable and terminates both through a single 1/2 inch knockout, which is how electricians pick up a second home-run or fixture whip on a box that has no spare openings left.
4) Is the Bridgeport 630-DC2 UL listed for commercial and inspected work?
It is UL listed under file E20534 and RoHS compliant, and it meets NEMA FB-1. That combination is what an inspector or a facility spec typically asks for on flex and AC cable terminations.
5) I only need to land one run of flex, not two - what should I order instead of the Bridgeport 630-DC2?
The Bridgeport Fittings 630-DC2 is a duplex strap connector, meaning it brings two lengths of flexible metal conduit or armored cable into a single knockout. For a single run, a straight one-piece FMC connector such as the Thomas & Betts 306 Straight Tite-Bite connector is the style to look at; the 306 is a non-insulated fitting for 1 inch FMC, so confirm the trade size matches your conduit. The Bridgeport duplex fitting is built for 3/8 inch flex going into a 1/2 inch knockout.
6) Can I use the Bridgeport 630-DC2 duplex connector on liquidtight flexible conduit in a wet location?
No. The 630-DC2 is a strap type duplex fitting for 3/8 inch flexible metal conduit and 14/2 to 10/3 armored cable, rated NEMA FB-1, and a strap-and-screw design does not seal the conduit. For liquidtight flexible conduit you need a purpose-built liquidtight fitting such as the RACO 4734 SWIVEL-LOK, a 1 inch Type B liquidtight multi-position connector in nylon. Match the fitting to the conduit type the drawing calls for.
7) How does the cable get secured in this strap type connector, and do I need extra hardware?
Two Phillips/slotted head screws clamp the strap down over the conduit or cable, so it takes nothing more than a screwdriver. The screws are part of the fitting; the only thing not included is the locknut side you would already be handling at the box.
8) Is a zinc die cast duplex connector suitable for damp or corrosive areas?
The body is die cast zinc with a ball burnished, mirror smooth finish, which gives it good corrosion resistance and a clean look on exposed work. It is rated NEMA FB-1, which is a fittings and boxes standard, not a wet or liquidtight rating. For a liquidtight run, use a fitting built for it such as the RACO 4734 SWIVEL-LOK Type B liquidtight connector.
9) What is the difference between this duplex connector and a single straight flex connector?
A duplex fitting like the 630-DC2 lands two cables in one 1/2 inch knockout. A single connector, for example the Thomas and Betts 306 straight Tite-Bite, terminates one run per opening, and the 306 is a 1 inch FMC fitting rather than 3/8 inch. Use the duplex when knockouts are scarce; use singles when you have openings to spare or a larger trade size.
10) If I want to cut down on separate fittings, is there a box with the connector built in instead of using the Bridgeport 630-DC2?
Yes. The 630-DC2 is a standalone fitting you install into a 1/2 inch knockout on an existing enclosure. If you are setting a new box anyway, the RACO 232MSCM is a 4 inch square welded box, 2-1/8 inches deep with an M bracket, from the STAB-IT series with the connector integrated into the box. Note the Bridgeport duplex fitting still has the advantage of landing two runs of 3/8 inch flex in one knockout, so check how many cables you are bringing in before you switch approaches.
11) What makes the Bridgeport 630-DC2 different from a standard Tite-Bite style flex connector?
The Bridgeport 630-DC2 uses a two-screw strap with Phillips/slotted heads that clamps down over the conduit or cable, and it accepts two runs into one knockout. A squeeze or bite style fitting like the Thomas & Betts 306 straight Tite-Bite connector is a single-entry FMC fitting sized for 1 inch conduit and supplied non-insulated. The Bridgeport fitting is zinc die cast with a ball burnished, mirror smooth finish and carries UL listing under file E20534 with RoHS compliance.
12) How much room does this fitting take up inside the enclosure?
Overall it measures 2.1875 by 1.625 by 0.61 inches, so plan for a little over two inches of length where the two cables converge. On a shallow box or a tight gutter that matters more than the KO size does.
13) Is the Bridgeport 630-DC2 made in the USA?
Yes, country of origin is the United States. That answers the domestic-content question that comes up on government, school, and healthcare purchase orders.
