== Procedure <ref name = "ref3" /> ==
=== Prepare the Wire ===
[[File:Crimp1.png|thumb|150px]]* Check if any strands of the stranded wire to see if any strands have loosened and expanded spread out to be larger than the wire and the insulation together. If In case this has occurredhappened, twist the wires to the size they were before they were strippedstripping. * The cut should be nice and clean. Check the insulation to ensure that there has been a nice clean cut. Wires Don't use wires with damaged insulation should .* Ensure that the stripping tool has not cut/nicked any wire. If you see any nicked wires, you must cut and re-strip the wire before crimping. This ensure that there is no reduction in the amount of current that can be usedcarried
===Setup and Operate a Hand Crimp Tool===
[[File:Crimp2.png|thumb|150px]]#Ensure that you have the hand correct crimp tool . Check if it is designed to crimp the for your specifications of size wire and the proper terminal shown on by looking in the Hand Crimp Tool Specification sheet.#Place If the above check is passed, place the terminal in the tool. #If you are using a locator, lift the locator and insert the terminal in the proper nest with the barrel up and against the locator bar. Release the locator blade to hold the terminal in position.
#Insert the wire.
#Squeeze the handle.
#Inspect for proper crimp location.
 == Importance of Proper Crimping <ref name = "digikey"/> ==
Proper attachment of terminal to the wire is critical. Mechanical as well as electrical connections are important - The result of a properly crimped joint is a reliable mechanical and electrical connection. <br \>
The mechanical connection is refers to the crimping of the terminal to the conductor. It must be so secure enough that it does not to vibrate loose or to be pulled off through normal use. <br \>The electrical characteristics are just as equally important. The major concern is the amount of electrical resistance caused by the mechanical joint which crimp is a major concern, because it determines the crimped joint’s ability of the crimp joint to conduct current.

One indication of the importance of proper crimping is evidenced in a study for the Space Shuttle Program that traced 28% of all defects to improperly assembled wiring and connectors.<ref name = "digikey"/>

== Tips for Crimping <ref name = "instructable">http://www.instructables.com/id/How-to-Make-A-Quality-Crimped-Joint/</ref>==
=== Step 1: Choosing the Wire ===
Depending on your application, you You may or may not have a choice on the say in deciding which wire to use, depending on your application. Firstly do not use Avoid solid cored wire, and if you want a reliable job definitely avoid solid wire.!
=== Step 2: Determine the wire size ===
This The wire size may be listed in a number of several ways, the most common being . AWG (American Wire Gauge)(e.g. 16 AWG), Cross is the most common. Otherways are listing the cross sectional area in square mm millimeters (e.g. 1 sq mm) or strand and diameter count (e.g. 32/0.2). <br \>If you are buying a new wire, the its size will be listed on the reel or packet. <br \>Many These days, many wires are now have this information printed into in the insulation with this information , and repeated along the length. Insulation If you use standard wires, then insulation diameter should not give you a significant issue. In other cases, it is important very crucial for the most reliable crimps as it affects how the rear of the crimp grips the wire, however as long as you use standard wires, then this should not give you a significant issue.
=== Step 3: Choosing the Crimp Terminal ===
Now you know what wire size you have, you will also need to work out what you need to connect to. There are many, many variations of crimp, but there are a handful of very common ones. <br \>The terminal must be of have sufficient cross section size and conductive material that it is as good as an electrical conductor <br \>The surfaces of the terminal and wire and terminal that are pressed into contact in the crimp must be clean and . They should be free of heavy, non-conductive films such as oxides, sulfides, and similar substances

'''Pre-Insulated Terminals<ref name = "instructable"/>''' <br \>If you are using pre-insulated terminals have a heat sleeve to grip the wire insulation.All terminals are sold with a defined wire size range- this should be listed on the packet, but if not and you are using pre-insulated parts you can tell the wire size by looking at the colour of the sleevecolor.
The generally adopted standard is:
* '''Red Insulation:''' 0.5-1.5mm2 / 22-16 AWG
* '''Blue Insulation:''' 1.5-2.5mm2 / 16-14 AWG
* '''Yellow Insulation:''' 4.0-6.0mm2 / 12-10 AWG
There are other colours around, but you are unlikely not likely to come across these unless you are doing industrial, aerospace or military work.
