Issue:
Product Design Features
Product Line:
Load Centers, Safety Switches, Metering
Environment:
Knockout Pattern
Cause:
Application
Resolution:
The knockout patterns in the products should be more than sufficient to accommodate conduit sizes for the wires required to supply the product for its maximum amperage rating and should not be cut or enlarged in the field.
BUT if for some reason a KO pattern needs to be expanded (or Cut larger than the maximum KO size), that will be between the installer and the local code authority. Always check with the local Code BEFORE expanding or cutting knockout patterns larger than what is factory supplied. With the approval of the local code authority, expanding knockouts won't be a violation in the UL listing and in the warranty.
