Installing Conduit and Cable
A second form of hardwood brace (not shown) is a yolk type, in which the
cables are passed through. Make sure the holes are small enough to provide a
snug fit for the cables. The connectors or lugs are attached to the cables and
cables are bolted to the terminals.
When using the hardwood bracing method and the short circuit current is less
than 42,000 A, brace the cables every 12 in. (305 mm). When the short circuit
current is 42,000 A or greater, brace the cables every 6 in. (153 mm).
Incoming Line Brace
Allen-Bradley manufactures an incoming line brace similar to the hardwood
clamping-type brace. To order an incoming line brace, contact your local
Allen-Bradley distributor or Rockwell Automation sales representative and
reference assembly number 40113–848.
IMPORTANT
Install lugs so they are in line with each other and proper spacing is used
between phases. Hardware must be torqued per the torque tables found on
the enclosure door.
