Product Overview
Copper Conductor Quadruplex Service Drop Cable 600V is a neutral-supported overhead service cable with three phase conductors and one bare neutral messenger, assembled in a quadruplex (four-conductor twisted) configuration. Phase conductors: concentrically stranded compressed soft copper, insulated with PE (75°C) or XLPE (90°C). Neutral: bare hard-drawn copper, solid or stranded. The quadruplex configuration provides three 120V phase legs plus a grounded neutral for 120/208V three-phase wye service — the standard for multi-family residential buildings, small commercial services, and light industrial applications requiring three-phase power from an overhead drop.
Service Drop Cable Comparison
| Duplex | Triplex | Quadruplex | |
|---|---|---|---|
| Conductors | 1 phase + neutral | 2 phase + neutral | 3 phase + neutral |
| System | 120V 2-wire | 120/240V 3-wire | 120/208V 3-phase 4-wire |
| Typical Use | Small loads, lighting | Standard residential | Multi-family, commercial, 3-phase |
Phase Conductors (×3)
Concentrically stranded compressed soft copper per ASTM B-8. PE (75°C) or XLPE (90°C). 45 or 60 mils insulation.
Neutral Messenger
Bare hard-drawn copper, solid or 7-strand per ASTM B-1. Supports full mechanical tension of the overhead span.
Quadruplex Assembly
Three insulated phases twisted around the bare neutral. Single-cable overhead drop for complete 3-phase service entrance.
Applicable Standards
