Application
Used to supply power, usually from a pole-mounted transformer, to the user's service head where connection to the service entrance cable is made. Also suitable for installations for street lighting, security lights, and temporary service for construction. To be used at voltages of 600 volts phase-to-phase or less and at conductor temperatures not to exceed 75 潞C for polyethylene insulated conductors and 90 潞C for cross-linked polyethylene (XLP) insulated conductors.

Specifications
Meets or exceeds the following ASTM specifications:

• B-1 Hard-Drawn Copper Wire.
• B-3 Soft or Annealed Copper Wire.
• B-8 Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard, or Soft.

Meets or exceeds all applicable requirements of ANSI/ICEA S-76-474 for polyethylene and cross-linked polyethylene insulated conductors.

Construction
Conductors are concentrically stranded compressed soft copper insulated with either cross-linked polyethylene, or conventional polyethylene.
Neutral messengers are either solid or concentrically stranded bare hard-drawn copper.

Notes:

• Code words for XLP insulated products are formed by adding ""XLP"" to the conventional polyethylene code words above (e.g.-Theta/XLP).
• Ampacity figures for black insulation only. Based on conductor temperature of 75 潞C for polyethylene insulated conductors, 90 潞C for XLP insulated conductors, ambient temperature of 40 潞C 2 ft./sec. wind in sun.
