Multi-Contact Assembly Tools

This section offers the tools necessary for making MC4 (Locking type multi-contact) extension wires. Generally, one MC4 Male connector and one MC4 Female connector are attached to each end of a #12 or #10 USE2 wire.

The components of the MC connector system for photovoltaics are designed to allow time-saving and safe serial and parallel wiring of PV modules for building-integrated and free-standing solar installations.
