The components of the MC plug connector systems for PV are designed to permit timesaving, dependable series cabling of PV modules which are integrated into buildings or are stand alone arrays. MC plug connector system allows for the PV arrays to be pre-assembled and pre-wires in the shop or on site. Then the completed arrays can be installed quickly by skilled construction workers.

Making Connections: Connections from modules to cord extensions are made by simply plugging the lead from the panel into the corresponding male/female extension plug. Easily snapping together for proper connection and weather tightness. Plastic "locking" devices (under development) will snap over the connector to ensure a strong mechanical union.

Wire Losses: All of the cord extensions manufactured by Energy Outfitters are #10 AWG. 

Recommended Installation Methods: Measure the length of wire needed to run from the PV module or PV array's terminating connection to the disconnect/combiner box. Using an MC cable that is long enough to handle both the positive and negative runs, cut the cable to the required length. This will leave you with two cords, one with a male MC connector and the other with a female MC connector. Properly route the extension cables to the combiner and make the connection using the cut ends. After all the connections have been made in the PV combiner box, complete the circuit by snapping the male and female cord extensions to the appropriate PV module or array.

Safety Issues: As with all electrical connections, safety should be your highest priority. Make certain all MC connections are completely engaged and tight. Do not use connectors that do not fit correctly or are loose. When entering the combiner/disconnect box, always use the correct strain relief to ensure weather tightness. Always torque the connections in the combiner/disconnect box to the manufacturer's specifications. Also, be sure to observe proper polarity as many of the system components are not protected against reverse polarity and severe damage can result, voiding the manufacture's warranty and possibly causing physical injury.
