Conversions Tech 4-Port Insulated Tap Connector — 1/0 AWG to 750 MCM, NEC 230.46 Line-Side Rated
Conversions Tech 4-Port Insulated Tap Connectors are engineered for reliable multi-conductor connections in demanding electrical distribution environments. Each connector features UV-resistant plastisol insulation, a rounded ergonomic housing, and set-screw termination for precision mechanical strength and long-term conductivity. Designed to meet NEC Article 230.46, these connectors provide a code-compliant solution for line-side service applications in residential, commercial, and industrial systems.
Key Features and Advantages
- Secure Set-Screw Connections: Adjustable set screws and precision-machined aluminum body deliver a high-pressure clamping force that minimizes electrical resistance and ensures long-term connection integrity.
- Four-Port Single-Side Entry: Simplifies conductor arrangement by allowing up to four wires to be connected through a single entry side — ideal for parallel or tap connections between 1/0 AWG and 750 MCM conductors.
- NEC 230.46 Compliance: Fully compliant with National Electrical Code Article 230.46, authorizing its use for line-side connections on service equipment and panelboard assemblies.
- Ergonomic, Rounded Design: Smooth plastisol coating provides improved grip and eliminates sharp edges during field installation, reducing installer fatigue and risk of insulation damage.
- Removable Protection Plugs: Each port and set screw is fitted with a removable plug to prevent ingress of debris, dust, and moisture before and during installation.
- Pre-Filled with Oxide Inhibitor: All ports are pre-loaded with conductive oxide inhibitor gel to prevent galvanic corrosion and maintain low contact resistance between aluminum and copper conductors.
- Heavy-Duty Insulation: Plastisol coating provides UV, chemical, and abrasion resistance, maintaining mechanical and dielectric performance under outdoor and industrial conditions.
- Professional-Grade Construction: Dual-rated AL9CU aluminum alloy body supports both copper and aluminum conductors, certified to UL 486A/B and cULus standards.

Frequently Asked Questions (FAQs)
1. What makes this connector suitable for NEC 230.46 line-side use?
It meets the requirements of NEC Article 230.46, which defines acceptable methods for line-side tap and service equipment connections. The insulated design, UL 486A/B certification, and voltage rating ensure full code compliance.
2. How many conductors can this tap connector accommodate?
This model supports up to four conductors through single-side entry ports, simplifying parallel or multi-feed connections.
3. Can this connector be used with both copper and aluminum wires?
Yes. It is dual-rated for AL9CU, which authorizes the connection of both aluminum and copper conductors under UL 486A/B standards.
4. What protection does the plastisol insulation offer?
The heavy-duty plastisol coating provides exceptional UV, chemical, and abrasion resistance, making it suitable for indoor and outdoor environments.
5. What is the function of the oxide inhibitor gel?
The pre-filled oxide inhibitor minimizes oxidation and galvanic corrosion, maintaining low contact resistance and long-term reliability in copper and aluminum terminations.
6. What is the rated temperature and voltage?
Rated for continuous use at 90°C with a 600-volt maximum operating voltage, cold-temperature rated to −45°C for harsh environments.
7. Is this connector UL Listed?
Yes. It is UL Listed under File No. E186991 and tested to UL 486A/B for mechanical and electrical performance standards.
8. What is the torque requirement for installation?
The recommended tightening torque is 275 in-lbs using a 9/16″ hex driver to ensure optimal electrical compression without damaging the conductor.
9. Can this connector be used outdoors?
Yes. Its UV-resistant plastisol insulation and moisture-sealed ports make it ideal for outdoor and direct-exposure installations.
10. What applications are best suited for this product?
Applications include electrical distribution panels, service disconnects, HVAC units, switchgear, solar systems, and industrial equipment where durable multi-conductor taps are required.
