Voltage Types and Conductor Count
The Engage Cable is available for either 240VAC split phase or 208VAC three phase (Separate models
are available for 230 VAC service). All cable connectors bear labels indicating their cable voltage
designation. Typically used for residential applications, 240VAC cabling includes four conductors. Three-
phase 208VAC cabling includes five conductors and is used for most commercial installations. Because
Enphase microinverters output onto two phases, three phase cabling balances the phases by rotating the
conductors from one microinverter to the next as shown in the following diagram.
Cabling Length Options
Engage Cabling is available in shorter lengths with 30 or 40 connectors, depending upon voltage type.
Longer lengths can be ordered and cut to suit per order. Ordering options include:
