Different kinds of cables and electrical wire are commonly used by the homeowner or electrician when performing routine wiring tasks. These tasks are fairly easy to do but practice with the techniques involved always helps. Before actually working with a type of wire or cable that is new to you, cut off a short piece and try stripping, joining, etc. Experiment a bit to find out which of the tools you have available are easiest for you to use and which do the best job. A little time spent in trial and error will make the job go faster.
Permanent indoor installations are made by running lengths of wire between outlets and switches along or inside walls, floors, and ceilings. An electrical circuit always needs a hot and a neutral conductor plus a ground for safety.
How to Remove the Plastic Sheathing from Plastic-Sheathed Electrical Wire
Armored cable or metallic-sheathed electrical cable has been in use since 1896 (in the U.K.) and in its most basic form contains two electrical conductors (black-hot and white-neutral) each individually insulated and both usually wrapped with a spiral of paper which is in turn enclosed in a flexible metallic sheathing such as shown in our abandoned-wire photograph below.

Cutting-tool method for stripping BX armored cable:
Make certain that the electrical power has been turned off and that you've used a test tool such as a VOM or neon tester to confirm that the wires you're working on are not electrically live. Failure to take this step risks a fatal electrical shock.
After Stripping the BX jacket from electrical wire
Protect the conductor wires (hot & neutral) from future damage from the sharp edges of the cut armored cable jacket. To eliminate the possibility of sharp edges of the armor cutting into the conductor insulation, a fiber bushing should be inserted under the armor, at the point where the conductors emerge.
