3-8 Electrical Installation
Installation with Only a Neutral Conductor Provided
Installations where no grounding conductor is provided must comply with article 250-32 of
the National Electrical Code. If the installation in question meets all of the requirements of
article 250-32, the following guidelines must be observed:
• Connect the grounding electrode cable at the local disconnect, never at the display power
termination panel.
• A disconnect that opens all of the ungrounded phase conductors should be used.
• The neutral and the ground conductors should be bonded in the display power termination
panel.
Refer to Figure 37 for installation details.
