This is fairly self explanatory. My only suggestion here is to use decent wire cutters similar to the ones pictured. In this photo I've chosen a pair of Klein High-Leverage Cable Cutter's Part No. 63050. They cost about $20.00 at Home Depot & Chanel-Lock also makes a set that are slightly less money but they do a rather sloppy cut in comparison to the Klein. The right tool, for the right job, is always well worth the expense.
Using a set of Diagonal Cut Pliers or "Dykes" as they are normally called will not make as clean or as nice a cut as a good set of cable cutters will and will not work very well at all as the wire gauge gets bigger. I can cut up to 2/0 battery cable with these Klein cutters.
