What would you use to crush the wire terminal around a wire?
Insert one wire into each end and crush the tube onto each wire with a pair of fine-nosed pliers or blunt wire cutters (but if you use wire cutters, take care not to cut into the tubing).
Should I use ferrules?
In addition to providing protection against damage, ferrules offer mechanical advantages during wiring by preventing the splaying and over bending of individual litz wire ends. This is particularly beneficial when performing multiple rewiring operations in the control cabinet – not least from a safety point of view.
Can you put two ground wires one screw?
Most screw terminals are designed for only a single wire. No you can’t.
Is there a DIY way to terminate wire for screw terminals?
Now for the correct DIY way to terminate wires for screw terminals, there are three that are practical and might be worth mention.
Is there a way to avoid tin in screw terminals?
The ways of avoiding the need to tin have been solved and are pretty practical. Firstly most professional screw terminals these days have a flat pressure pad or tongue that protects the wire from the turning screw end and keeps the wire end strands in order. Often solid wire conductors are used in alarm and telephone applications.
Can a hot gun be used on a screw terminal?
The extra high reliability terminals for aviation and aerospace use may have a crimp and internal solder so they can be reflowed with a hot gun after crimping to flow the solder and shrink the strain relief/insulation boot to seal the wire end from moisture and gas while making better electrical contact after an already sound mechanical connection.
How is a wire terminated in a PLC?
In factory automation (PLC) and distribution boards the wires are systematically terminated with bootlace ferrules (little thin wall copper (thin tin plated, not solder dipped) tubes with a plastic funnel) that are carefully crimped (or just squashed with a pair of pliers) onto each wire end before termination starts.
