Compatibility

Designed as an OEM-style replacement or new-installation component for 3-phase copper power distribution applications in commercial and industrial electrical enclosures and panelboards.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel or enclosure before installing or servicing the distribution block. Verify that conductor sizes and torque values for terminations comply with the block manufacturer specifications and NEC requirements. Do not mix copper and aluminum conductors at the same terminal without a listed connector rated for that purpose.
