Tired of stiff cables that break during installation?
You know the struggle. You are on a job site, trying to run speaker wire through a tight conduit or around a corner. The cable is too stiff. It kinks. The jacket gets stuck, or worse, the copper conductors snap inside because the stranding is too coarse. You waste hours fixing mistakes, and your crew gets frustrated. You need a wire that pulls easy, bends without breaking, and meets strict safety codes without costing a fortune. This is where the Belden 5000UP steps in. It is not just a wire. It is a solution for the real headaches you face in commercial and residential installations.
What makes Belden 5000UP the pro choice?
This cable is built for the real world. It uses 12 AWG bare copper conductors with a 65×30 stranding count. That means it has 65 tiny strands of copper in each conductor. This high strand count makes the cable super flexible. You can bend it around corners easily without worrying about internal damage. The jacket is made of heavy-duty PVC. It is tough against abrasion but smooth enough to slide through walls. It also includes a ripcord. This little string inside the jacket makes stripping the outer insulation fast. Your installers save time and money on every foot they pull. It is available in grey, which is perfect for professional looks in commercial spaces.
Technical Specs that matter to you
Let’s look at the numbers. This wire is designed to perform.
- Conductor Size: 12 AWG (American Wire Gauge). This is the sweet spot for medium to long speaker runs. It handles power well without being too thick.
- Conductor Material: Bare High-Conductivity ETP Copper. It is not tinned copper. It is pure copper for the best signal flow.
- Stranding: 65×30. This specific stranding gives the best balance of flexibility and strength.
- Number of Conductors: 2. Perfect for standard stereo speakers or single-zone audio.
- Insulation & Jacket: PVC (Polyvinyl Chloride). It resists moisture and chemicals found in building materials.
- Voltage Rating: 300 Volts RMS. Safe for most low-voltage audio and control circuits.
- Temperature Range: -20°C to +75°C. It works in freezing attics and hot equipment racks.
- Outer Diameter: 0.302 inches. It fits standard connectors and conduit fittings.
- Weight: About 59 lbs per 1000 feet. It is heavy enough to feel quality, but light enough to carry.
- Compliance: CL3 rated, RoHS compliant, and meets UL standards.
Electrical Performance Data
You need to know if the signal gets through cleanly. Here is the hard data on how this cable performs electrically:
- DC Resistance (DCR): 1.56 Ohms per 1000 feet. Low resistance means less power loss over long distances. Your speakers get the full power from the amplifier.
- Capacitance: 32 pF/ft (Nominal Conductor to Conductor). Low capacitance keeps the audio signal crisp, especially for high frequencies.
- Inductance: 0.16 µH/ft. This helps maintain audio quality over the length of the run.
- Max Recommended Current: 26 Amps per conductor at 25°C. This is way more than you need for speakers, which means the wire runs cool and safe.
Where should you use this cable?
This wire is versatile. It fits many jobs. The “CL3” rating is key here. It means you can use it inside walls in commercial buildings, like offices, retail stores, and schools.
- In-Wall Speaker Systems: The PVC jacket is rated for indoor wall use (non-riser, non-plenum). It is perfect for running behind drywall.
- Commercial Audio: Use it for paging systems, background music, and conference rooms.
- Security and Intercoms: It works great for low-voltage control circuits in security systems.
- Portable Setups: Because it is flexible and durable, it is also great for temporary stage setups or portable PA systems that get moved around a lot.
- Power Limited Control: Use it for thermostat wiring, door bells, or low-voltage lighting control.
Safety and Standards Compliance
You cannot afford to use non-compliant wire in a building. It is a fire hazard and a code violation. Belden 5000UP checks all the boxes for the USA and international markets.
- UL Listing: It meets UL 1685 and UL loading standards for flammability.
- NEC Code: It is CL3 rated. This allows it to be run in walls, floors, and ceilings according to National Electrical Code rules.
- RoHS: It complies with EU Directive 2011/65/EU. It does not contain banned hazardous substances.
- ISO Standards: It passes IEC 60332-1-2 flammability tests.
- California Prop 65: It meets the strict safety standards for chemicals in California.
Physical Construction Details
Let’s look inside the cable. Quality comes from the materials.
- Conductors: Solid bare copper. High conductivity means better sound.
- Insulation: Each conductor has its own PVC insulation. It is color-coded (usually black and white, or other colors depending on the batch) so you can keep polarity straight.
- Jacket: The outer black or grey PVC jacket protects against physical damage. It is UV resistant for short-term outdoor exposure before installation, but it is designed for indoor use.
- Ripcord: Yes, it has a ripcord. This makes jacket removal fast. No more nicking the copper while trying to cut the plastic.
- Markings: The jacket has print markings. You will see the Belden logo, part number, and footage markers. This helps you count feet as you pull it.
Available Colors and Lengths
We know you need options for different jobs. This model comes in several colors to help you identify runs.
- Black: Standard for most installs.
- Grey: Great for blending into grey walls or industrial settings.
- White: For clean looks in homes or drop ceilings.
- Blue: Often used for control circuits or specific audio zones.
- Green: For custom labeling.
Lengths:
- 500 feet reels (Unreel or Reel)
- 1000 feet reels (1000 ft is the standard bulk box)
