How Do You Punch Down a 110 Block?

Punch-down blocks often are used for networks and telephone systems because of how versatile they are.

A 110 punch-down block is a large circuit used to connect computer networks, telephones, and other wiring applications that run on low voltages. Punch-down blocks such as the 110 block are used because they offer a large variety of configuration options. There are two common types of 110 punch-down block configurations; horizontal and vertical. Place metal wires into the slots on the block with a punch-down tool when wiring a punch-down block.

Things You'll Need

• Punch-down tool
• Wire stripper

Instructions

1. Strip about 2 inches from the outer jacket of the cable you want to punch down.

2. Separate the conductor pair. Do not untwist them more than 1/2 inch. This will ensure best performance.

3. Place each pair in the correct slot. Punch down each pair using the punch-down tool. Place the blade of the punch-down tool on the selected terminal, and press firmly downward until the wire is fully inserted into the terminal.

4. Trim excess wire. Place strain relief caps over the connection.

Tips & Warnings

• Punch down connectors from the center of the block to the outside. This will ensure proper performance.
