How does NEMA 3R outdoor busway system compensate for expansion when mounted outdoors?

Issue:
Expansion and contraction due to climate.  Is a separate expansion joint required?

Product Line:
Busway

Environment:
Products sold in North America

Resolution:
We do not offer busway expansion joint rated for outdoor use.  Any expansion or contraction of outdoor busway can be accomodated dated by the busway joints and/or the fittings (elbows, tees, etc) included in the layout.
