EM Group Tubular Ring Terminal 16mm² M8 Tinned Copper

The EM Group tubular ring terminal is a high-quality electrical component engineered for the secure termination of 16mm² conductors. Constructed from premium tinned copper, this terminal ensures optimal electrical conductivity and long-term protection against oxidation and environmental corrosion. Its robust design makes it a reliable choice for maintaining stable power distribution in demanding electrical systems.

Advantages

The primary benefit of this tubular ring terminal is its superior material composition, which facilitates efficient current flow while minimizing resistance. The tinned copper finish provides an essential barrier against rust and corrosion, making it suitable for use in environments where moisture or temperature fluctuations might otherwise degrade standard copper connections. Its precise engineering ensures a tight, vibration-resistant fit when secured with an M8 bolt, contributing to the overall safety and longevity of the electrical installation.

Suitable for

• Industrial power distribution panels
• Residential electrical wiring systems
• Automotive and marine battery cable connections
• Grounding and earthing applications
• Renewable energy system installations

When it may not be suitable

This terminal is specifically designed for 16mm² conductors and is not compatible with cables of significantly different gauges. Using it with undersized or oversized wires may result in a poor mechanical connection or overheating.

Furthermore, this component is intended for use with M8 mounting hardware. It will not fit correctly on smaller or larger studs, which could compromise the integrity of the electrical contact.

Key specifications

• Conductor cross-section: 16mm²
• Stud hole diameter: M8
• Material: Tinned copper
• Design: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the end of the 16mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for tubular terminals to compress the barrel firmly onto the wire, ensuring a gas-tight connection. Once crimped, place the ring end over the M8 stud and secure it tightly with a nut and washer to ensure a stable electrical interface.

What to consider before purchase

• Verify that your cable gauge is exactly 16mm²
• Ensure the mounting stud size is M8
• Check that you have the correct crimping tool for tubular terminals
• Assess the environmental conditions to ensure tinned copper is appropriate for your specific application

Usage recommendations

Always perform a pull test after crimping to ensure the conductor is securely fastened within the terminal barrel. Ensure that all contact surfaces are clean and free of debris before tightening the M8 nut to prevent high-resistance connections.
