Installation Notes

Installation and operation should be performed by a qualified electrician familiar with knockout punch tooling and NEC conduit installation requirements. Always de-energize and lock out the work area before punching knockouts in live panels or enclosures. Confirm the die and punch are properly seated and aligned in the SPEED PUNCH System driver before applying force. Inspect the die for wear or damage before each use and replace if the cutting edge shows deformation.
