Copper building wire for a 600V tray run is not specified the same way as cable for a 15kV or 35kV distribution system. Commodity Cables offers copper VNTC-TC-ER and MC Copper for commercial, industrial, and utility projects. Within the MC Copper family, MV-105 is organized into 15kV and 35kV subcategories. In-stock orders placed by 2:30 PM can ship the same day from one of 11 warehouse locations.
VNTC-TC-ER and MC Copper serve different parts of the power distribution system. MC Copper is the parent product family for the MV-105 15kV and MV-105 35kV subcategories. Use this comparison to separate 600V tray and exposed-run applications from medium-voltage work before reviewing the full product documentation.
| Cable Family | Verified Details | Project Fit |
|---|---|---|
| VNTC-TC-ER | 600V Type TC-ER cable with copper conductors, PVC and nylon insulation components, a PVC jacket, and UL 83 and UL 1277 listings. | Tray, exposed-run, and direct-burial applications supported by the product marking. |
| MC Copper | Parent product family containing the MV-105 15kV and MV-105 35kV subcategories. | Medium-voltage power distribution requiring the appropriate 15kV or 35kV cable. |
| MV-105 15kV | MC Copper subcategory with a copper conductor, 133% no-lead EPR insulation, copper tape shield, low-friction PVC jacket, and UL 1072. | 15kV medium-voltage distribution. |
| MV-105 35kV | MC Copper subcategory with a copper conductor, 133% no-lead EPR insulation, copper tape shield, low-friction PVC jacket, and UL 1072. | 35kV utility and industrial distribution. |
VNTC-TC-ER uses uncoated annealed copper conductors, PVC insulation with an individual nylon layer, a flame-retardant PVC jacket, and a bare copper ground conductor. Its marking includes Type TC-ER, THWN-2, 90C wet or dry, FT4, sunlight resistance, oil resistance, and direct burial.
Available construction tables document three-conductor and four-conductor configurations with ground. Buyers should match the gauge, conductor count, footage, and installation conditions to the approved project documents.
MC Copper includes two MV-105 subcategories organized by voltage class: 15kV and 35kV. Both use copper conductors, 133% no-lead EPR insulation, copper tape shielding, and a low-friction PVC jacket. They support approved installations in wet or dry locations, conduit, ducts, direct burial, and cable tray.
The required system voltage determines which MC Copper subcategory to review. The 15kV one-core table covers 2 AWG through 1500 MCM. The 35kV one-core table covers 1/0 AWG through 1500 MCM. Both product documents also include three-core constructions and list operating limits of 105C for normal operation, 140C for emergency overload, and 250C for a short circuit.
Copper building wire supports power distribution across commercial construction, industrial manufacturing, utility infrastructure, and data center projects. VNTC-TC-ER can support suitable 600V tray and exposed-run applications, while the MC Copper MV-105 subcategories address 15kV and 35kV medium-voltage systems. Final cable selection should follow the project specification, installation conditions, and applicable product documentation.
Provide the details that determine product selection and availability:
VNTC-TC-ER is the 600V tray-cable option in this category. Confirm the required gauge, conductor configuration, and installation conditions against the project documents before ordering.
The required system voltage determines which MC Copper subcategory to review. The two MV-105 subcategories use similar documented construction, but each has its own voltage class and size table.
Review the matching product sheet and approved project specification. Confirm voltage class, conductor size, configuration, installation conditions, required compliance, and submittal requirements before releasing the purchase order.
Depending on the system design and product requirements, copper building wire may be used in renewable energy, water and wastewater, transportation, and institutional facility projects. Buyers should confirm the cable family, voltage class, installation conditions, and required listings with the approved project documents.
