NACS Tesla EV Charging Cable Open End Bare Wire | 3.5kW-15kW

Product Overview

This NACS open‑end charging cable features a standard NACS connector at one end and pre‑stripped bare‑wire terminals at the opposite end. Certified with ETL safety and FCC electromagnetic compatibility standards, this cable is engineered as a core component for EV charging equipment manufacturers, system integrators and maintenance service providers.

Instead of a complete ready‑to‑use charger unit, it is a high‑quality gun‑cable assembly for integration into your own EVSE host. Built with heavy‑duty TPU outer jacket, it withstands outdoor UV exposure, wide temperature fluctuations and repeated bending for long‑term commercial and residential operation. Cable length and conductor gauge can be customized to satisfy different AC charging power requirements.

Key Features

✅ Standard NACS Interface
Original‑compatible NACS connector for North American EVSE systems. Ergonomic curved‑handle design reduces fatigue during frequent plug‑in & unplug operations, robust anti‑impact housing for heavy‑duty daily usage.

✅ Open Bare‑Wire Terminals for Easy Integration
One‑end stripped bare wire design. No extra gun housing disassembly required. Technicians can directly connect wires to internal terminals of charging station hosts, ideal for new‑unit assembly, on‑site retrofitting and damaged‑cable replacement.

✅ ETL Safety & FCC EMC Certification
Compliant with North American market access requirements. ETL safety certification guarantees electrical safety; FCC certification ensures low electromagnetic interference, helping your finished products pass local regulatory audits.

✅ Weather‑Resistant Heavy‑Duty Cable
Premium TPU cable sheath delivers excellent resistance against abrasion, UV ray, cold‑hot cycling and outdoor aging. High flexibility prevents crack from thousands of bending cycles for all‑weather installation.

✅ High‑Performance Copper Conductor
High‑purity copper inner conductors minimize electrical resistance and heat buildup during continuous charging, delivering stable power transmission and extending service life of the whole charging system.

✅ Flexible Customization Available
Support custom cable length and conductor cross‑section gauge to match different AC power ratings. OEM service is available for bulk project orders.

Important Purchase Notes
 > Please read carefully before placing orders

1. This is a semi‑finished cable assembly ONLY
This product contains only NACS gun and cable with bare wires. Controller board, relay and full charger host are NOT included. It **cannot work by direct connection to mains power**. It must be wired to a compliant EVSE charging host unit.

2. Parameter confirmation before ordering
Please confirm required cable length and conductor gauge according to your charging power rating. Different current‑rated cables cannot be mixed in application.

3. Professional installation required
Bare‑wire terminals shall be wired by qualified electricians. Improper wiring may lead to equipment failure and safety hazards.

4. Market compliance reminder
ETL and FCC certifications are targeted for North‑American market. Please verify local regulatory requirements if exporting to other regions.

5. Lead‑time for custom orders
Custom‑length or special‑spec bulk orders require dedicated production lead‑time. Sample lead‑time differs from mass‑production orders. Please confirm lead‑time with sales in advance.

6. Warranty scope
Warranty covers manufacturing defects of cable and connector only. Damage caused by wrong wiring, violent mechanical impact, unauthorized modification and improper outdoor operation are excluded from warranty coverage.
