Bridgeport Fittings 845SP – Frequently Asked Questions

1) What cable types does the Bridgeport 845SP connector work with?
The Bridgeport 840 Series SP connector, model 845SP, is built for AC, MC, and MCI-A cable terminating into a box or enclosure. It is a 3/8 inch trade size fitting, which is the size used for standard AC/MC cable runs. If you are landing something other than AC/MC type armored cable, this is not the fitting for it.
2) Does the Bridgeport 845SP snap into the knockout or does it need a locknut?
It snaps in. The E-Z Lock front end pushes into the knockout and holds, so there is no locknut to thread on from inside the box. That is the whole labor argument for the SP version: one hand on the fitting, then a single set screw to clamp the cable.
3) What knockout size does a 3/8 inch AC/MC snap-in connector fit?
A 3/8 inch trade size AC/MC connector like the 845SP is made for the standard 1/2 inch knockout found in outlet boxes, panels, and enclosures. Trade size on these fittings refers to the cable end, not the knockout.
4) Is the Bridgeport 845SP UL listed for code inspection?
It is NRTL listed under UL file E20534 and carries a NEMA FB-1 rating, and Bridgeport states its fittings meet the bonding and grounding requirements for this class of connector. Those are the two lines an inspector or a spec writer usually wants on the submittal.
5) Can a RACO 4734 liquidtight connector be used in place of a Bridgeport 845SP for AC/MC cable?
No. The Bridgeport 845SP is a 3/8 inch trade size zinc die cast connector made to terminate AC/MC/MCI-A armored cable into a box or enclosure, secured with a single set screw. The RACO 4734 is a 1 inch Type B liquidtight multi-position connector in nylon from the SWIVEL-LOK series, built for liquidtight flexible conduit rather than armored cable, and in a different trade size. If the run is AC or MC cable at 3/8 inch, the 845SP is the correct fitting; use the liquidtight connector only where 1 inch liquidtight flexible conduit terminates.
6) Will a zinc die cast AC/MC connector hold up in a damp mechanical room?
The body is die cast zinc with a ball burnished, mirror smooth finish, which Bridgeport specifies for corrosion resistance and for clean cable entry without snagging the armor. That covers ordinary indoor commercial and industrial environments. For wet locations or anywhere a liquidtight seal is called for, you want a liquidtight fitting instead, such as the RACO 4734 SWIVEL-LOK multi-position liquidtight connector.
7) How big is the Bridgeport 845SP connector body, and will it clear a crowded panel wall?
Compact. The fitting measures 0.8125 inch in length, 0.4375 inch in width, 0.375 inch in height, and 0.365 inch in depth, so it takes very little room behind the knockout when you are stacking multiple MC drops into one gutter or panel side.
8) Are Bridgeport 840 Series connectors made in the USA for Buy American jobs?
Country of origin is the United States, and Bridgeport is an American manufacturer. That matters on federal, municipal, and institutional work carrying Buy American procurement language.
9) What is the model number to order for the Bridgeport 3/8 inch snap-in AC/MC connector?
Order model 845SP. That is the 3/8 inch AC/MC/MCI-A snap-in version of the Bridgeport 840 Series. One set screw, zinc body, no locknut required.
10) I need a 4 inch square box with a built-in connector - is the Bridgeport 845SP the same idea?
No, they solve different parts of the job. The Bridgeport 845SP is a standalone 3/8 inch connector that snaps into a knockout and clamps the AC/MC cable with one set screw, so it goes into whatever box or enclosure you already have. The RACO 232MSCM is a 4 in. square welded box, 2-1/8 in. deep with an M bracket and a STAB-IT connector already integrated, so the cable entry is part of the box. Buyers standardizing on plain knockout boxes typically stock the 845SP separately; buyers who want the box and cable entry in one part number go to the 232MSCM.
11) For bonding a service to an intersystem point, does the Bridgeport 845SP do that job?
No. The 845SP is a cable termination fitting: it carries a NEMA FB-1 rating and is NRTL listed under UL file E20534 for connecting AC/MC cable into a box. For bonding separate systems at the service, the Burndy BDTIBB BONDIT is the wall mount intersystem bonding connector, in stainless steel and rated for #14 through #2 AWG conductors. Electricians finishing a service typically need both parts: the 845SP where armored cable lands in the enclosure, the BDTIBB at the intersystem bonding termination point.
12) I need a box with the connector already built in instead of loose fittings. What is the alternative?
If you would rather not land separate connectors, a box with an integral cable clamp does the same job. The RACO 232MSCM is a 4 inch square welded box, 2-1/8 inch deep, with STAB-IT connectors and an M bracket. The Bridgeport 845SP is the right choice when you are terminating into an existing box, panel, or enclosure knockout.
