Failure to follow these instructions will result in death or serious injury.
NOTE: Refer to Line Side Barrier and Neutral Bonding Strap Kits, page 38 for
information.
NOTE: The terms “neutral bonding strap” and “neutral bonding cable”, describe
the components which meet the requirements for a “neutral bonding conductor”.
These are equivalent terms.
100 or 250 A Maximum NQ Panelboards
To install a neutral bonding strap on NQ panelboards with mains rated up to 225 A
(with main lugs or main circuit breaker), or up to 250 A with a factory assembled main
circuit breaker, refer to Bonding Strap Installation—100 or 250 A Maximum NQ
Panelboards, page 11, and follow the instructions below.
1. Align the bonding strap on the side rail, as pictured.
NOTE: For some applications, it may be necessary to remove the lug (not
pictured) before installing the bonding strap.
2. Insert the two mounting screws, as pictured. Tighten the 10-32 screw to 10–12
lb.-in. (1.1–1.4 N•m) and the 1/4-20 to 25–30 lb.-in. (2.8–3.4 N•m).
NOTE: Lug mounting screws are provided in the bonding strap bag assembly.
a. If the lug was removed in step 1 above, reinstall it on top of the bonding
strap.
b. Use 1/4-20 x 9/16 in. screw in mounting for 100/225 A interiors with no
options. Refer to note C and D for other options.
c. Use the 1/4-20 screw x 11/16 in. lug mounting screw on applications with
feed-through lug, sub-feed lug, sub-feed circuit breaker, or 200% neutral
applications.
d. Use the 1/4-20 x 7/8 in. lug mounting screw on applications with 200%
neutrals and with feed-through lugs, sub-feed lugs, or sub-feed circuit
breakers.
