Thomas & Betts XD012-TB – Frequently Asked Questions
1) What is the difference between an expansion coupling and an expansion/deflection coupling like the XD012-TB?
A straight expansion coupling only takes up movement along the length of the run. The XD012-TB is an expansion/deflection type, so it handles both axial expansion and contraction and angular deflection, which is what you want at a building seismic or settlement joint where the two sides move in more than one direction. If your only concern is thermal growth in a long straight run, a plain expansion fitting is the simpler choice.
2) Do I need an expansion/deflection coupling where conduit crosses a building expansion joint?
Yes, that is the job this fitting is built for. A rigid coupling across a structural joint transfers building movement straight into the conduit and the boxes at each end. The XD012-TB, at 5 inch, lets the two halves of the run move apart, together, and out of line without stressing the raceway. Install one at each point the conduit crosses the joint.
3) How do I make sure I am ordering the right Thomas & Betts XD coupling?
Order by the part number, not by description alone. XD012-TB is the 5 inch expansion/deflection coupling from Thomas & Betts. The XD series uses a different number for each trade size, so matching the number is the only way to be sure the coupling matches the conduit on the drawing.
4) What is the Thomas & Betts XD012-TB coupling body made of?
Ductile cast iron. That is the structural body material for the 5 inch XD coupling, chosen for the loads a 5 inch conduit run puts on a joint that has to move.
5) Is the XD012-TB a coupling or a complete fitting with everything needed?
It is a coupling, the Thomas & Betts XD012-TB in 5 inch. It joins two conduit ends at the movement point. Bonding across the joint is a separate consideration on your install, and any straps, supports, or bonding jumper for the run are ordered separately.
