Choose the correct size wire and crimp tag for the job.

Avoid whiskers.

Ensure that there is a small amount of bare wire visible either side of the crimp.
This is to ensure that there is not an excessive amount of insulation trapped under the tag which could give poor continuity.

Fit one lead only into each tag.

Some crimps tags have one crimp for the wire and a second one for the insulation.
Ensure that insulation is visible either side of the second one to ensure good clamping.

Rubber or heat shrink sleeving can be fitted to improve insulation and SPRINGYNESS.

Ensure that this sleeving is not trapped under screw heads or nuts when fitting the lead.
