NEMA VE‐2:General “How‐to” guidePrescribes methods for proper handling, storage, and installation of the cable tray.
Guidelines for proper support locations
“The support span should not be greater than the straight section length, or as recommended by the manufacturer, to ensure no more than one splice is located between supports.”
Steel Cable Tray Supports
Supports Can Be a Significant Cost
Trapeze Support$75 ‐ $250/support
Engineered Pipe Racks$1,500 ‐ $15,000/support
Why the “Current State?”• NEMA VE 2 supplies recommendations for the installation of cable tray
including support locations for fittings
B‐Line Recommended Support Locations
• B‐Line fitting support spans exceed NEMA VE‐2
• B‐Line requirements provide more flexibility in the field
• Fewer supports decreases project cost –materials and labor
• Tested to NEMA 20C
B‐Line vs NEMA VE‐2• NEMA VE‐2 allows for manufacturers recommendations for location of
supports– Fitting Support Locations NEMA VE‐2 4.4.1:
• “…unless otherwise recommended by the manufacturer…”
B-LineNEMA VE-2
Added Flexibility for Horizontal Fittings
Some Math…• Horizontal Fitting Example
– Steel weighs ~31lb/ft– Opportunity to reduce ~40’ of steel
– Results in ~1240lbs of steel removed
– How many times can this be repeated??
B‐Line reduces structural steel and labor to install it!!
Analysis Cost Summary• B‐Line’s analysis of large EPC project BOM shows the following
cost savings based upon $175/support
Solution Cost Savings– Fitting Support Solutions: $1,220,625.00
TOTAL SAVINGS: $1,220,625.00

Additional Savings Opportunities• Longer spans of Tray
– 30 and 40 foot lengths• 57A, S8A
• Reducing # of supports with longer span reduces overall cost
– As distance increases, savings increase
Long Span Trays cost savings Example
Savings greater than total cable tray cost!!!

Analysis Cost Summary• B‐Line’s analysis of large EPC project BOM shows the following cost savings
based upon $175/support
Solution Cost Savings– 3m to 6m support span $1,471,401.00– Fitting Support Solutions: $1,220,625.00
TOTAL SAVINGS: $2,692,026.00• EPC also estimated 7500 man our reduction due to structural steel savings
solution, welding and installation• 15,383 supports can be eliminated at 7.5kg = 115,373kg of weight savings
Straight Run Supports• NEMA VE‐1 load test
• NEMA VE‐2 and B‐Line recommend placing splices at ¼ span to decrease deflection
B‐Line and NEMA Recommendation
• Splice plate at ¼ span• Reduces deflection up to 50%• Increases rigidity of system
Best Installation for tray – not always for project
Splice located on supports – Simple Beam
• Standard splice plates and expansion splice plates on support
• Eases design criteria• Potential for MAXIMUM DEFLECTION
More common actual installation practice than ¼ span
Current State ‐ Expansion/Contraction
• NEMA VE‐2 Section 4.3.2 requires supports within 2’ on both sides of an expansion splice
Splice often on support to satisfy NEMA for expansion
Splicing on Supports• Splicing on supports
creates issues– Simple beam – max
deflection due to max positive moment at support location
– Potential for guide and splice hardware interference
Current State – Splicing Long Runs
• Environmental– Expansion/Contraction concerns
• Performance– Deflection
Outdoor applications present significant challenges
NEMA VE‐2 Recommendation• Splice Location
– ¼ span• Aesthetics
– Minimum Deflection– Reduced ~50%
• NEMA 4.3.2– Support within 2’ of expansion splice

• Superior load carrying versus C‐ChannelC‐section side rail profile:‐ 6” high x 16ga side rail‐ 86lbs/ft on a 12’ span
I‐beam side rail profile:‐ 6” high x 16ga side rail‐ 208lbs/ft on a 12’ span
How Can B‐Line Do This…?• Material (aluminum)
• I‐beam siderail
• Wedge‐Lock Splice
