Thomas & Betts LB57SA – Frequently Asked Questions
1) Does the LB57SA come with a cover and gasket?
The LB57SA is ordered as the conduit body itself. Covers and gaskets for a form 7, 1-1/2 inch LB are separate line items, so add them to the order if you need to close the opening.
2) I need a 2 inch LB body, not 1-1/2 inch - what should I order instead of the LB57SA?
The LB57SA is built for 1-1/2 inch conduit, so it will not serve a 2 inch run. For a 2 inch opening, the Arlington Industries 935NM AnyBODY LB-style conduit body is a 2 inch threadless non-metallic body. Confirm your raceway accepts a threadless connection rather than threaded hubs before ordering.
3) When do I use an LB conduit body instead of an LL, LR, or T body?
An LB turns the run back through a wall, the back hub facing the structure and the end hub facing along the conduit, which is what you want where a riser enters a building or a panel. LL and LR bodies turn left or right in the same plane instead, and a T body gives you a third opening for a branch. The LB57SA covers the back-entry case in 1-1/2 inch.
4) Is the LB57SA conduit body suitable for outdoor or damp locations?
The body is sand cast aluminum, which is the usual choice for exterior and damp-location conduit work because it does not rust like ferrous fittings. To make the installation weatherproof you still need a gasket and a cover rated for wet locations; aluminum alone does not seal the opening.
5) Can I use an aluminum conduit body like the LB57SA with galvanized rigid steel conduit?
Mechanically the threads mate, but aluminum against galvanized steel is a dissimilar-metal contact. Most installers either stay with aluminum conduit and fittings throughout or treat the joint with an approved anti-seize/joint compound. The LB57SA body is sand cast aluminum.
6) Can I use a non-metallic LB conduit body instead of the aluminum Thomas & Betts LB57SA?
Only if the trade size and connection method match your run. The LB57SA is 1-1/2 inch and sand cast aluminum with threaded hubs. The Arlington 935NM AnyBODY is a non-metallic LB-style body in 2 inch threadless, so it is not a size-for-size swap for a 1-1/2 inch threaded opening. A metallic body also carries the equipment grounding path through the raceway, while a non-metallic body does not, so the grounding method for the circuit has to be accounted for separately when you substitute material.
7) How do I order the exact part number for this 1-1/2 inch aluminum LB body?
Order it as Thomas & Betts LB57SA. That single part number covers the 1-1/2 inch form 7 LB in sand cast aluminum, with no finish or handing options to specify.
