Instructions
Application Use these instructions to install a neutral connection plate in a Bulletin 2100
motor control center section. Instructions apply to the following kits:
•
Catalog number 2100H-NPC1 and 2100H-NPS1 (for top horizontal
wireway)
•
Catalog number 2100H-NPC2 and 2100H-NPS2 (for incoming line
compartment or for 0.5 space factor units)
•
Catalog number 2100H-NPC3 and 2100H-NPS3 (for bottom horizontal

Recommended Tools Screwdriver, 5/16” and 7/16” wrench or socket, torque wrench
Installation Refer to Figure 1, 2, or 3, and use the following steps to install a neutral
connection plate:
1. Make sure that all power has been disconnected.
2. Remove the unit support pan or top horizontal wireway pan from the
appropriate location. (See Publication 2100-5.0 for removal
instructions.)
3. Replace the unit support pan or top horizontal wireway pan with the
modified unit support pan or modified horizontal wireway pan.
If there is interference from other parts, unassemble the neutral
connection plate assembly from the pan, and install the pan.
4. If necessary, reattach the neutral plate assembly. Torque to 45 lb-in
(5 N-m).
5. For catalog numbers 2100H-NPC3 and 2100H-NPS3 (for bottom
horizontal wireway): If unit support pan removed in Step 1 has a latch/
interlock bushing installed, remove this bushing and reinstall it on the
pan supplied with the kit. Torque to 32 lb-in (3.6 N-m).
Important: If the feed to the neutral connection plate kit is separated from
the phase conductors by a complete path of magnetic material,
the current that is feeding the neutral connection plate kit must
not exceed 280 amperes rms. Lug supplied has a wire capacity
of #6-250 kcmil and should be torqued to 370 lb-in (41.8 N-m).

ATTENTION: De-energize all power sources to the motor
control center before installing neutral connection plate.
Failure to de-energize all power sources can result in severe
injury or death.
