8/10/12 Positions 600V 15A Dual Row Wire Screw Terminal Blocks with Cover & 400V 15A Pre-Insulated Barrier Strips Jumpers - 6 Pack

Dual Row Terminal Block & Jumper Strip Kit (8/10/12 Positions)

Key Features

• Complete Wiring Solution: This comprehensive 6-set kit includes heavy-duty dual-row terminal blocks and matching pre-insulated jumper strips in 8, 10, and 12-position configurations, providing maximum versatility for complex circuit organization.
• High-Capacity Electrical Rating: The terminal blocks are rated for up to 600V and 15A, while the included jumper strips are rated for 400V and 15A, safely accommodating a wide range of industrial, automotive, and high-draw DIY applications.
• Protective Safety Covers: Each terminal block comes equipped with a transparent, snap-on polycarbonate cover to protect the screw terminals from accidental physical contact, preventing dangerous short circuits and electrical shocks.
• Pre-Insulated Barrier Strips (Jumpers): Includes easily trimmable red and black jumper strips that allow you to quickly bridge multiple adjacent terminals together to create a common bus, eliminating the need for messy, stripped wire loops.
• Secure Screw-Clamp Connections: Features high-quality brass alloy conductor plates and heavy-duty zinc-plated screws that provide maximum torque, ensuring a tight, vibration-resistant grip on your wires.

Product Specifications & Included Components

• Kit Contents: 6 total terminal blocks (typically two 8-position, two 10-position, and two 12-position) with matching transparent covers and red/black jumper strips.
• Terminal Block Rating: 600V, 15A (Maximum).
• Jumper Strip Rating: 400V, 15A (Maximum).
• Wire Compatibility: Designed to securely hold and connect 22 AWG up to 12 AWG solid or stranded electrical wire.
• Standard Model Equivalents: TB-1508 (8-Position), TB-1510 (10-Position), TB-1512 (12-Position).

Universal Compatibility & Applications

These universal wire terminal blocks are ideal for organizing and securing complex wiring layouts across multiple disciplines:

• Automotive & Marine: 12V/24V accessory wiring, boat distribution panels, and RV electrical upgrades.
• Home Automation & Audio: Speaker wire distribution, LED lighting arrays, and low-voltage home relay boards.
• Industrial Controls: CNC machine power supplies, PLC wiring, and custom electronics enclosures.

When to Use or Upgrade

• Messy Wiring Upgrades: Replace twisted, taped, or poorly spliced wire clusters with a clean, professional, and easily traceable distribution block.
• Power Distribution: Use the included red and black jumper strips to create a common power (positive) and ground (negative) bus bar to feed multiple devices from a single main wire.
• Corroded Connections: Replace old, rusted, or stripped terminal blocks in marine or outdoor enclosures that are causing intermittent power failures or high resistance.

Installation & Wiring Tips

• Safety First: CRITICAL: Ensure all power sources (batteries, breakers, or power supplies) are completely disconnected before installing or modifying any wiring.
• Proper Wire Stripping: PRO TIP: Strip approximately 1/4 to 3/8 of an inch of insulation from your wire. While bare wire works, using crimp-on fork or ring spade terminals provides the most secure, professional connection under the screw heads.
• Customizing Jumpers: The pre-insulated barrier strips can easily be cut with heavy snips or side-cutters if you only need to bridge 3 or 4 terminals instead of the entire row.
• Mounting the Blocks: Secure the blocks to your mounting surface or enclosure using the pre-drilled mounting holes at each end of the base before attaching your wires to prevent stress on the connections.
