Bridgeport Fittings 501-DC2 – Frequently Asked Questions
1) What size MC or AC cable will a Bridgeport cable connector accept?
The Bridgeport cable enclosure connectors take 14/2 through 10/3 AC/MC cable, or 14/2 through 10/3 MC-PCS cable, which works out to a cable outside diameter of .42 to .61 inch. Measure the jacket OD on what you are pulling; if it falls in that window you are good. There is also a version built for larger cable, the 561-DC2, which covers a 61 to 87 OD range on a 3/4 inch knockout.
2) Which Bridgeport connector do I order for a 1/2 inch knockout versus a 3/4 inch knockout?
Knockout size is the first thing to pin down. For a 1/2 inch knockout the models are 501-DC2, 560-DC2, 570-DC2 and 570-DCI2. For a 3/4 inch knockout, 4157-DC covers the 43 to 61 cable OD range and 561-DC2 covers the larger 61 to 87 range. There is also a 563-DC2 on a 1/4 inch knockout. Match the knockout in the box or fixture first, then check that your cable OD falls in that model's range.
3) Does the Bridgeport zinc die cast cable connector maintain the equipment ground path?
It does. The zinc die cast body carries the bonding path from the cable armor through to the enclosure, and the connector is suitable for maintaining grounding continuity when it is installed per the NEC. That is what lets the armor or the MC-PCS assembly serve its bonding role instead of you having to run a separate path.
4) Is the Bridgeport MC cable connector UL listed for a permitted commercial job?
UL listed and RoHS compliant, with a NEMA FB-1 rating. FB-1 is the fittings standard an inspector expects to see on a commercial or institutional installation, so this satisfies a spec that calls for listed fittings on AC/MC terminations.
5) Will a Bridgeport MC cable connector fit a light fixture knockout that has flats around it?
Yes. These connectors are built to fit knockouts with flats, the kind you find on lighting fixture housings, so the locknut seats properly instead of riding up on the flat. That is a common failure point with connectors sized only for a plain round KO.
6) Do I need an anti-short bushing with these Bridgeport MC connectors?
The connector has an insulated throat that protects the conductors up to 105 degrees C, so the wire is not bearing on a raw metal edge as it passes into the box. Note that the insulated throat is a feature of the connector body and does not by itself replace the red anti-short bushing that armored cable installation practice calls for at the cut armor end; follow the cable manufacturer's instructions and the NEC on that point.
7) How does the tri-drive screw on a Bridgeport MC connector get tightened?
One screw does the whole job. Push the cable into the connector and tighten the single tri-drive screw to lock it. Tri-drive means you can drive it with a flat blade, a Phillips, or a nut driver, whichever is already in your hand. Tighten it with a screwdriver by hand, not with an impact.
8) Can I use a Bridgeport set screw connector on 3/8 inch flexible metal conduit as well as MC cable?
Yes, the set screw connector handles 3/8 inch flexible metal conduit along with MC, MCI-A and MC-PCS cable, so one fitting covers a fixture whip and a homerun on the same job. Set screw ends secure either the conduit or the cable armor in the same body.
9) What is the difference between the Bridgeport 570-DC2 and the 570-DCI2?
Both are 1/2 inch knockout connectors covering the same 42 to 61 cable OD range, so they land on the same cable and the same box opening. The DCI2 is the insulated throat variant of the pair. If your spec or your local inspector calls for an insulated throat on the termination, order the 570-DCI2; otherwise the 570-DC2 does the same mechanical job.
10) Will a zinc die cast connector hold up in a damp mechanical room or parking garage?
Zinc die cast is naturally corrosion resistant, which is why Bridgeport uses it for long term service in any environment, and the fittings are burnished so the surface stays bright. For a property manager standardizing on one fitting across a portfolio, that is the practical reason to spec die cast zinc over a plated steel connector.
11) Are Bridgeport cable connectors made in the USA for a Buy American job?
Bridgeport Fittings is an American manufacturing company, which is the reason these connectors get specified on public and institutional work carrying domestic sourcing language. Confirm the specific model against your project's Buy American documentation requirements before submitting.
