Bridgeport Fittings MLB-46 – Frequently Asked Questions
1) Do the MLB conduit bodies thread directly onto rigid conduit, or do I need adapters?
The hubs are NPT threaded, so rigid metal conduit and IMC screw straight into the body with no adapter or coupling in between. Match the trade size of your run to the body size (2, 2-1/2, 3 or 4 inch) and thread it in.
2) Are Bridgeport MLB mogul conduit bodies UL Listed for a commercial inspection?
They are UL Listed under File No. E11077 and rated NEMA FB-1, and the series meets the NEC 6X rule for conduit body pull applications. That is the paperwork an inspector on a commercial or institutional job will ask for.
3) Why choose a mogul conduit body instead of a standard LB?
Mogul bodies like the MLB series use a split diagonal cover and a larger internal body so there is real room to get large conductors around the bend during a pull. A standard-size body of the same trade size is tighter inside. On 2 inch and up, especially 3 and 4 inch with big feeders, the mogul is what keeps you from damaging insulation on the pull.
4) How much clearance do I need to mount a 4 inch Bridgeport MLB body?
Plan for a body height of 10.38 inches. On the largest MLB-50 at 4 inch trade size you also want swing room on the cover side, since the split diagonal cover has to come off in place for pulling and later inspection.
5) Does the MLB conduit body come with the cover and gasket, or is that ordered separately?
The MLB series is a cover system: the split diagonal cover is part of the conduit body design rather than a separate catalog item. What you do supply on the job is the conduit itself and any locknuts or sealing compound your installation calls for.
6) Can I use an MLB mogul body outdoors or in a wet location?
The MLB series carries a NEMA FB-1 rating, which is the standard covering fittings and conduit bodies for the environmental conditions they are marked for, and the aluminum body is finished in grey enamel paint. For a specific wet or hazardous classification, go by the NEMA type marking on the body you receive rather than assuming from the series.
