Types of Wire Strippers
There are two main types of wire strippers currently available on today’s market. This includes standard wire strippers and automatic (self-adjusting) wire strippers. Each of these two individual types of wire strippers is designed to accomplish a common goal, by stripping the insulator from a wire’s conductor, so that viable connections can be established.
The main difference between standard wire strippers and automatic wire strippers is how they accomplish this task.
Standard Wire Strippers
Standard wire strippers operate under the same general concept as a pair of pliers. However, when closed, standard wire strippers pierce a wire’s insulator, allowing it to be pulled from its conductor with manual force.
Each jaw pertaining to a set of standard wire strippers features divets of an exact size, that correspond with an identical divet that is present on the stripper’s opposite jaw. When these jaws are closed together, a conical-shaped orifice is created, through which a wire is pulled during stripping.
Standard wire strippers feature orifices of graduating size, which allows for multiple gauges of wire to be stripped.
Automatic (Self-Adjusting) Wire Strippers
Automatic wire strippers operate through the actuation of two individual jaws, which are mechanical in nature. These jaws are manipulated through the closing of the stripper’s handles, and compress downward at their inner edges.
A wire is inserted above a designated lip, which is directly beneath the pair of actuating jaws. The combination of these components creates a pinch point, in which wire is held during the act of stripping.
As a set of automatic wire strippers’ handles are squeezed together, the wire is pinched, its insulator is pierced, and each individual section of the insulator is pulled apart. This style of stripper is known as self-adjusting because it automatically articulates to fit any wire size.
Understanding Wire Gauges
When first dealing with wiring of any type, many are often confused by the idea of various wire “gauges”. However, this concept is often easier to understand than one might think. When speaking of wire, the term gauge is used as a sizing reference. More specifically, a gauge measurement refers to a particular wire’s diameter.
As a general rule, the lower a wire’s gauge number is, the larger its diameter. Likewise, the higher a wire’s gauge number is, the smaller its diameter.
For example, a 16 gauge wire is smaller in diameter than a 14 gauge wire. This can be assumed without ever physically comparing each wire, because of the fact that 14 gauge is a lower numerical rating than 16 gauge.
Initially, this can be a somewhat difficult concept to grasp. However, with a little practice, one will become adept at the nuances of wire sizing and gauge designations quite quickly.

How to Use Wire Strippers
Both standard and automatic wire strippers carry their own individual methods of use. While the procedures pertaining to each differ quite notably, either type of wire stripper can be successfully used with a little prior knowledge.
- Select Appropriate Hole – Before one can proceed to strip the insulator from their wire, they must first decide which size hole best fits their particular wire size. While some strippers feature stamped sizing designations that correspond to each hole, others do not. In any event, the hole that is selected must snugly fit around a wire’s insulator.
- Twist Strippers – In order to remove all insulative material to the most efficient degree possible, one should rotate their strippers back and forth before exerting force. This evenly severs the insulator that is to be stripped.
- Pull Outward – You will now pull outward on your wire strippers while holding a firm grip on the wire in question with your other hand. If done correctly, the end portion of the wire’s coating will be pulled free in the process.
- Place Wire Into Strippers – Begin by placing the wire that is to be stripped, between the stripper’s mechanical jaws, and the flat shelf directly below. You will measure the length of wire that will be stripped, by lining this spot up with the central meeting point of each mechanical jaw.
- Squeeze Handles – You will now squeeze both of the strippers’ handles together. This will actuate the unit’s mechanical jaws, and pull the severed insulator apart. After releasing the unit’s handles, you should notice that a severed segment of the insulator has now been upward along the conductor.
- Inspect Wire – Upon stripping your wire, it is important to inspect for the presence of an unstripped or missed insulator. While automatic wire strippers do tend to be quite efficient, they can leave behind small amounts of unsevered insulator on occasion.
