Pin Count & Wire Gauge Chart

Terminal blocks come in different sizes and pin counts to match various wiring needs. Use this quick chart to select the right model for your project.

Pin Count	Wire Gauge (AWG)	Typical Use Case
2-Pin	18–26 AWG	Power input, small modules, sensor connections
3-Pin	16–26 AWG	Signal + power lines, motor driver inputs, LED drivers
4-Pin / 5-Pin	14–22 AWG	Stepper motors, multi-wire sensors, CNC wiring
6-Pin and above	12–20 AWG	Distribution blocks, high-current connections, multi-channel systems

How to Connect Wires Using Terminal Blocks

Strip the wire: Remove 5–7 mm of insulation without damaging the copper strands.

Open the terminal screw: Loosen the screw or lever until the wire slot is free.

Insert the wire: Push the copper into the terminal until fully seated.

Tighten securely: Tighten the screw until the wire is firmly clamped. Avoid overtightening to prevent damaging the conductor.

Test the connection: Gently tug the wire to ensure it does not come loose.

Power up and verify: Once all wires are connected, power your circuit and check stability.

Safety Tips for High-Current Terminal Block Connections

Use the correct wire gauge: Undersized wires can overheat and cause failure.

Ensure a tight, clean connection: Loose wires generate heat and may lead to arcing.

Avoid mixing stranded and solid wire in the same terminal - choose one type for consistency.

Use ferrules for stranded wires to improve grip and reduce fraying.

Check for discoloration or heat marks: These indicate poor contact or excessive load.

Never exceed the rated current: Check the terminal block’s datasheet for maximum current capacity.

Terminal Block

This terminal block with cage clamp connection is similar to the Wago 222 series. Wire terminal blocks are primarily used to make secure wire connections in industry, communications, networking, lighting, security, signaling, heating, ventilation and air conditioning. This terminal block connector allows you to interconnect solid, stranded, and fine wire cables without the use of tools. This terminal block accepts wire sizes from 28 AWG to 12 AWG. Compact connection terminal for up to 5 strippable conductors depending on the type of blocks. This wire connector is suitable for soft and hard wires. With the advantages of long life, corrosion resistance, aging resistance, high pressure resistance, insulation and flame retardancy, it can effectively prevent electric leakage. This makes the lever nut more secure than a traditional wire nut.

Check out the compatible wires for these terminal blocks.
