Knipex 98 66 20 Twist-On Connector

This Knipex twist-on wire connector accepts conductors up to 20 mm and is rated for 1,000 V AC. It is built for electricians and maintenance crews who need a secure splice on bare live cable ends. The red insulation identifies the connector in busy panels. It meets DIN VDE 0680-1 standards for electrical safety.

Installation notes and common issues

The connector twists onto stripped conductors by hand without special tools. A firm, even twist ensures full contact across the wire bundle. Under-twisting leaves gaps that increase resistance and heat. Over-twisting can damage fine strands or crack the insulation shell. Always verify that no bare copper remains exposed after the connection is complete.

Capacity and headroom

The 20 mm maximum wire size covers heavy-gauge power cables in industrial and automotive circuits. At 1,000 V AC rating it handles mains-voltage distribution and control wiring with margin. The 3.94 in overall length fits standard junction boxes and enclosures. It is not suited for cables exceeding the stated diameter or for voltages above the rated value.

Questions about this item

How can I verify the connector is working correctly after twisting it onto the wires?

After twisting the connector onto the bare live cable ends, check that the splice is secure and the insulation fully covers the joint; the 1,000 V rating applies when the connection is properly made.

What comes in the package and what must I source separately?

The package contains the red twist-on wire connector itself; you must supply the bare live cable ends up to 20 mm maximum wire size for splicing.

Which version should I choose for a 20 mm maximum wire size and 1,000 V requirement?

The 98 66 20 model in red is specified for a 20 mm maximum wire size and 1,000 V AC rating per DIN VDE 0680-1.
