Tip: If you’re ever unsure about the strip length, check the Linkwell product label or manual. Most terminal blocks have a recommended strip length printed right on the housing.
With the right tools, careful measuring, and good safety habits, you’ll get perfect strip length every time. That means reliable, safe connections for all your Linkwell terminal blocks.

Recommended Wire Stripping Lengths for Linkwell Terminal Blocks
When you work with terminal blocks, you want every connection to be safe and strong. The right strip length by terminal type makes all the difference. Let’s break down the best practices for each Linkwell terminal block style, so you can get your electrical projects done right the first time.
Screw Terminal Strip Length
Screw terminals are popular in many electrical panels. You see them in control cabinets, power distribution boxes, and even in telecom setups. These terminal blocks use a screw to clamp the wire in place. You need to strip just enough insulation so the conductor sits fully inside the barrel, but not so much that copper sticks out.
For most Linkwell screw terminal blocks, you should strip between 8 mm and 12 mm. This range gives you a solid connection without leaving any exposed wire. Always check the product label or datasheet for the exact strip length. If you use a wire ferrule, make sure the stripped part matches the ferrule length.
Here’s a quick checklist for screw terminal strip prep:
- Cut your wire clean and straight.
- Strip 8–12 mm of insulation.
- Twist stranded wires for a neat end.
- Insert the wire fully into the terminal block.
- Tighten the screw to the recommended torque.
Tip: If you see copper outside the terminal block, you stripped too much. If the insulation goes under the clamp, you stripped too little.
Push-In Terminal Block Strip Length
Push-in terminal blocks make wiring fast and easy. You just strip the wire, insert it, and you’re done. These blocks are common in automation, lighting, and control systems. The wire stripping length matters a lot here. Too much or too little can cause problems.
According to Linkwell, the standard wire stripping length for push-in terminal blocks is usually between 8 mm and 12 mm. Always check the specific block’s marking or datasheet. Most push-in types need a ferrule on stranded wires for the best grip.
Here’s how you get it right:
- Strip 8–12 mm of insulation.
- Use a ferrule for stranded wires.
- Insert the wire until it stops.
- Tug gently to check the grip.
Push-in terminal blocks save you time, but only if you strip the wire to the right length. If you go too short, the connection is weak. If you go too long, you risk exposed copper.
Spring Clamp Terminal Block Strip Length
Spring clamp terminal blocks use a spring to hold the wire tight. You find these in places where vibration or movement is common, like industrial machines or transport panels. The strip length is important for a secure electrical connection.
For Linkwell spring clamp terminal blocks, you should strip about 10 mm to 11 mm of insulation. This lets the conductor fit perfectly under the spring. Always use a ferrule for stranded wires. The ferrule keeps the strands together and helps the spring grip better.
Follow these steps for spring clamp strip prep:
- Cut the wire clean.
- Strip 10–11 mm of insulation.
- Add a ferrule if needed.
- Insert the wire until it stops.
- Release the spring to clamp the wire.
Note: If you strip too much, you might see copper outside the block. If you strip too little, the insulation can get caught under the spring, making a poor connection.
High-Current and Large Conductor Strip Length
High-current terminal blocks handle big wires and lots of power. You see these in power panels, energy storage, and heavy machinery. The strip length here is critical for safety and performance. If you get it wrong, you can create serious electrical hazards.
Check out this table to see what happens if you don’t strip the wire correctly in high-current terminal blocks:
| Strip Length Issue | Consequence |
|---|---|
| Too Little | Insulation caught under clamping mechanism, leading to poor or non-existent electrical connection. |
| Too Much | Exposed conductor creates shock hazard and increases risk of short circuits. |
For Linkwell high-current terminal blocks, always follow the datasheet. Most large conductor blocks need a strip length between 12 mm and 18 mm, depending on the wire size. Use a caliper or the block’s built-in gauge to measure. Make sure the conductor fills the barrel, but no copper sticks out.
Here’s a quick guide:
- Cut the large wire clean.
- Strip 12–18 mm of insulation (check the block’s specs).
- Insert the wire fully.
- Tighten the clamp or screw to the right torque.
Safety Alert: Double-check your strip length before connecting high-current wires. Mistakes can lead to overheating, arcing, or even fire.
When you follow these guidelines for each type of Linkwell terminal block, you get reliable electrical connections every time. The right wire stripping length keeps your projects safe, efficient, and up to code.
