Bridgeport Fittings 566-DC2 – Frequently Asked Questions

1) Which Bridgeport 566/660 cable connector do I need for 12/2 NM-B romex on a 1/2 inch knockout?
Use the 566-DC2. It's the 1/2 inch knockout size in the round cable series and covers (1) or (2) 14/2 up to (1) or (2) 12/2, plus (1) 14/2 to (1) 10/3. That's the everyday size for standard branch circuit romex into a metal box or panel.
2) What cable outside diameters do the Bridgeport 660 through 666 round cable fittings accept?
Each knockout size covers a specific OD band: 660-DC2 at 3/4 inch K.O. takes .680 to .800 inch, 662-DC2 at 1 inch takes .850 to 1.000 inch, 664-DC2 at 1-1/4 inch takes 1.090 to 1.300 inch, 665-DC2 at 1-1/2 inch takes 1.187 to 1.490 inch, and 666-DC2 at 2 inch takes 1.750 to 1.950 inch. Measure the cable jacket OD with calipers and match it to the band, not to the conductor size.
3) My cable OD falls between two of these Bridgeport ranges. Which one do I pick?
There's a gap between bands on purpose, and you should not force it. For example .800 to .850 inch sits between the 660-DC2 and 662-DC2 ranges, and 1.000 to 1.090 sits between the 662-DC2 and 664-DC2. A jacket under the stated minimum won't be gripped properly, and one over the maximum won't seat against the throat. Re-measure the jacket at its widest point and choose the fitting whose published range actually contains that number; if it lands in a gap, go up to the next size so the cable clamps within spec rather than at the edge.
4) I need to standardize cable connectors across a whole building. Does one series cover 1/2 inch through 2 inch knockouts?
Yes. The 566/660 round cable family spans six knockout sizes from a single series: 1/2 inch (566-DC2), 3/4 inch (660-DC2), 1 inch (662-DC2), 1-1/4 inch (664-DC2), 1-1/2 inch (665-DC2), and 2 inch (666-DC2). Same die cast zinc body, same FB-1 rating, same rectangular throat across all of them, so a facility can stock one family and cover every box opening.
5) Can I run two cables through one of these Bridgeport connectors?
Only on the 1/2 inch size, and only for the small gauges. The 566-DC2 is listed for (1) or (2) 14/2 or (1) or (2) 12/2, so two 14/2 or two 12/2 in one fitting is within its published range. A single 14/2 to 10/3 is also covered. The larger sizes in the series are specified by a single round cable OD band, so treat those as one cable per fitting.
6) Are these round cable fittings OK for round SOOW type cord, or only for NM cable?
The 566/660 series are nonmetallic cable fittings sized by round cable outside diameter, with the larger sizes (660 through 666) listed purely by OD band from .680 up to 1.950 inch rather than by wire gauge. They are rated FB-1, which is the NEMA standard for nonmetallic sheathed cable fittings, so specify them for nonmetallic sheathed cable applications. If the job calls for a liquid-tight cord grip or a strain relief connector, that's a different fitting family.
7) Is the Bridgeport 566/660 series zinc or plastic, and will it hold up in a damp mechanical room?
Die cast zinc, not plastic. Zinc die cast is corrosion resistant and dimensionally stable, and these are given a ball burnished mirror smooth finish so the cable jacket slides in without scraping. That's why they get specified for retrofit and industrial work where corrosion resistance matters more than cost.
8) How do I know the cable is inserted far enough into the connector?
The throat is rectangular and acts as a positive end stop for the cable jacket. Push the cable in until the jacket bottoms against that throat, and the cable is positioned correctly with the jacket ending inside the fitting rather than short of it. No guessing on insertion depth, which is the usual failure on cable connector installs.
9) Do these Bridgeport fittings satisfy a Buy American requirement on a government or institutional job?
Country of origin is the United States, and Bridgeport Fittings manufactures domestically. That's the detail institutional and public sector procurement asks for when a domestic content clause is in the contract.
