SYSTEM GROUNDING
To attach the WEEB Lug 10.3, insert the M10 T-Bolt into
the side slot on CrossRail and rotate clockwise 90 degrees.
Attach the remaining components, as shown, tightening the
Serrated Hex Nut to 15 ft-lb (20.3 Nm). Once the lug has been
installed, a #6 or #8 AWG solid copper wire from a DC ground
location external to the array must be inserted in the equip-
ment ground conductor location on the lug. Torque the bolt
to 5 ft-lb (6.7 Nm).
Note: Verify with your local jurisdiction that the WEEB Lug
10.3 is considered a single-use item in a UL 2703 Listed
System.
Warning: Employ best industry practices to ensure that cop-
per does not contact aluminum and galvanized steel.
Note: the WEEB Lug 10.3 utilizes a WEEB 11.5 as a bonding
washer and thus carries the markings of a WEEB 11.5

IMPORTANT NOTE
CrossRail components are required to be electrically bonded
and grounded via the Everest Ground Lug or Burndy’s WEEB
Lug 10 and the use of #6 or #8 AWG solid copper wire. A
minimum of one lug is required per each inde-pendent row of
modules.
To attach the Everest Ground Lug, insert the MK3 slot nut of
the pre-assembled ground lug into the top chan-nel of the
CrossRail. While slightly lifting the plastic tabs, rotate 90
degrees clockwise to engage the MK3 into the channel. En-
sure the bonding teeth are perpendicular to the rail channel.
Torque the M8 bolt to 10 ft-lbs using a 13 mm deep socket.
Insert a #6 or #8 AWG solid copper wire and tighten ter-minal
screw to 35 - 60 in-lb using a 7/16" socket.
