Splicing Q Cable and Raw Q Cable with Junction Boxes
For complex installations that include multiple arrays, it is possible to use raw Q Cable (Q-12-RAW-300) to
service the arrays and branch circuits that do originate directly at the primary roof mounted junction box. In
the case that Field Wireable Q Connectors are not readily available, a small junction box may be used to
splice two sections of Q Cable together or may be used to splice Q Cable to raw Q Cable.
The raw Q Cable is available in 300m (938ft) cable rolls (Q-12-RAW-300).
You must terminate the raw Q Cable in one of the following manners:
• Into a junction box using a ½” service entrance (SE) strain reliefs or UF cable glands
• With a Field Wireable Q Connector (male or female)
