Thomas & Betts TB57SA – Frequently Asked Questions
1) Will the Thomas & Betts TB57SA conduit body work in place of a Crouse-Hinds, Appleton or OZ Gedney Form 7 body?
Yes. The TB57SA is a Form 7 conduit body, and both the bodies and covers are interchangeable with Crouse-Hinds, Appleton and OZ Gedney Form 7 conduit bodies. That means an existing Form 7 cover and gasket from those brands will mate with it, which matters when you are patching one bad body into a run that was installed with another brand.
2) Does the TB57SA come with a cover and gasket, or do I order those separately?
The TB57SA is the Type TB conduit body itself. Covers are a separate item, and because it is a Form 7 body, Form 7 covers (including Crouse-Hinds, Appleton and OZ Gedney Form 7 covers) will fit it. Plan on ordering a cover and gasket to close the body out.
3) What standards does the Thomas & Betts TB57SA conduit body meet?
The TB57SA is listed to UL Standard, is CSA compliant, and meets Fed Spec W-C-586D. The federal spec reference is what institutional and government specifiers usually need on a submittal for conduit outlet bodies.
4) Can I use a Type TB conduit body to make a 90 degree turn instead of bending conduit?
Yes, that is one of its intended uses. A Type TB body turns a conduit run 90 degrees and gives you a removable cover at the corner, so you get a pull point and access to the conductors later instead of a sealed field bend. It also works as a pull outlet during the wire pull, as a splice point for branch conductors, and as a mounting outlet for wiring devices or lighting fixtures.
5) What thread type do Thomas & Betts Type TB conduit bodies use, and do I need a bushing to protect the wire?
Threads are tapered NPT, so the body threads directly onto standard rigid or IMC conduit with no adapter. Integral bushings are built in to protect conductor insulation at the hubs, so you do not add separate insulating bushings.
6) Is an aluminum conduit body like the TB57SA suitable for a food plant or chemical processing area?
The TB57SA is sand cast aluminum, and Thomas & Betts lists these Type TB bodies for food and beverage, pharmaceutical, chemical processing and other corrosive environments. For washdown areas, pair it with the matching Form 7 cover and gasket so the enclosure stays sealed.
7) How much clearance do I need to mount a TB57SA, and how heavy is it?
Outer dimensions are 8.5 x 6.5 x 4.12 inches and it weighs 1.42 lbs each, so it takes real space in a tray or on a wall and is light enough to hang off threaded conduit without extra support in most runs.
8) Is the TB57SA sold individually or in a multi-pack?
The TB57SA carries an outer quantity of 2, so case packs come two to a carton while the stated weight of 1.42 lbs is per piece. Order in even counts if you want full cartons.
9) What is the exact part number and UPC for the Thomas & Betts Type TB conduit body?
Manufacturer part number is TB57SA from Thomas & Betts, a Form 7 Type TB conduit body in sand cast aluminum. That MPN is what to quote so you get the TB configuration rather than another form or body style.
