Adding to its ongoing series of National Electrical Installation Standards (NEIS), NECA recently released NECA/NEMA 105-2002, Recommended Practice for Installing Metal Cable Trays. The standard covers installation and maintenance procedures for metal cable tray systems used to support power and communications cabling and is the first NEIS to be produced in partnership with the National Electrical Manufacturers Association (NEMA).

The standard was developed by NEMA’s Cable Tray Section and will be published by NECA. It is the 17th publication in the NEIS series and the ninth to be jointly produced with another industry group.

NECA/NEMA 105-2002 is $25 and can be ordered via phone at (301) 215-4504 or email by contacting
