Also Known As:

300-300-300-4/0 type r cable, 300-300-300-4/0 service entrance cable, 300-300-300-4/0 ser cable, 300-300-300-4/0 aluminum ser cable, 300-300-300-4/0 aluminum service entrance cable, 300-300-300-4/0 electrical entrance cable.

Conductors:

Aluminum type R cable has compact strand soft drawn 8000 series aluminum conductor, per ASTM B-801. The conductor is the electrode in the cable and is responsible for transmitting electric current. 

Insulation:

Aluminum SER cable has a type XHHW-2 cross linked polyethylene (XLP) insulation. The conductors are cabled together with a bare aluminum ground and covered with a reinforced binder tape. For color code, see table B in the technical section. 

Jacket:

The cable jacket used in its design is Polyvinyl Chloride (PVC). The jacket protects the inner components of the cable from potentially damaging external forces. PVC is robust and resistant to oil, sunlight, water, flames, acids, chemicals, radiation, impact, abrasion, and weather changes. Sequential footage markings that help the user identify the appropriate length during installation are noted on the cable jacket.
