MixBox M6/M8 Power Junction Post Connector Kit-120A 150A Brass Terminal Set

The Mix Box Power Junction Post Connector Kit is built for safe, reliable high-current connections. This set includes both 120A and 150A terminal posts in red and black pairs - ideal for battery banks, solar systems, automotive wiring, and other high-power applications. The housing is made from PA66 flame-retardant material, providing insulation and fire resistance. The conductive parts are solid brass, offering strong conductivity and resistance to overheating.

The 120A connectors use M6 screws, while the 150A connectors use M8 screws. Both are rated for voltages below 1000V. The red and black colour coding makes it easy to identify positive and negative terminals, reducing wiring mistakes. Whether you're building a custom battery box, upgrading a 4x4 dual-battery system, or working on a solar installation, this junction post kit gives you the components you need.

ASSEMBLY & USAGE GUIDE:

• Step 1 - Plan Your Connection - Determine where you need the junction posts. Common locations include battery boxes, power distribution panels, and firewall pass-throughs.
• Step 2 - Mount the Connectors - Use the appropriate screws (M6 for 120A, M8 for 150A) to mount the connectors to your panel or surface. Ensure they are secure.
• Step 3 - Connect the Cables - Strip your cables and insert them into the connector posts. Tighten the screws firmly to ensure good contact.
• Step 4 - Observe Polarity - Connect positive cables to the red connectors and negative cables to the black connectors. Double-check before tightening.
• Step 5 - Test the Connection - Use a multimeter to verify voltage and polarity before powering up your system.
• Step 6 - Insulate and Secure - Ensure all connections are insulated and cables are secured to prevent strain on the terminals.

QUICK TIPS:

• Check voltage rating - Suitable for systems below 1000V. Do not exceed this rating.
• Use correct screw size - M6 for 120A, M8 for 150A. Using the wrong size may damage the connector.
• Tighten securely - Loose connections can cause overheating and voltage drop.
• Observe polarity - Red for positive, black for negative. Double-check before connecting.
• Keep clean - Wipe with a dry cloth. Avoid moisture and contaminants.
• Use appropriate cable lugs - For best results, use ring terminals or cable lugs that match the post size.
• Insulate exposed connections - Use heat shrink or electrical tape to prevent short circuits.
