working Mathod

Electrical work can come in the form of anything from residential electrical wiring to high-tech electronic instrumentation. While there exist many specialty tools for different electrical purposes, there several tools that are universal to all electrical workers.
Wire strippers, or strippers, are the most common and universal tool that is used to do electrical work. Strippers are used to remove insulation from the ends of wires before they are terminated to some type of outlet or connector. They are available in a variety of different types and sizes to accommodate every gauge of wire. Two special versions include electrician scissors and thermal strippers. Electrician scissors have special notches which can be used to strip household size wiring with the assistance of a thumb. Thermal wire strippers use heat to break the insulation after which the insulation can be removed easily by hand.

Another common tool for electrical workers is a digital multimeter. Multimeters are the primary method of measuring voltage, resistance, and amperage within a circuit. The newest models can now also measure frequency, and perform diode checks. While there are meters available that measure only one electrical property, such as a volt meter, most electrical workers agree that having a meter that can read multiple electrical properties is very convenient.

A soldering iron is a tool that is used extensively in the electronics field. Soldering irons are used to permanently repair broken wires and to perform repair on circuit boards. A properly made solder joint entails melting solder in the desired location which creates the new, repaired connection upon drying. Common solder, which is normally a lead/tin mix, in melted around 750-800 degrees Celsius.

A tool that every electrical handy man uses is a crimper. Using a solderless crimp is often far more convenient and mush easier than soldering a broken wire back together. A solderless crimp is installed by crushing it down upon each broken wire end with a crimper, thereby restoring the circuit’s electrical continuity. While a soldered connection is viewed as a permanent repair, a solderless crimp is viewed by the electrical community as a quick fix.

When working with electronic instrumentation, it is often necessary to employ the use of a grounded wrist strap. These wrist straps protect sensitive electronics from being zapped by an ElectroStatic Discharge, or ESD. ESD is commonly felt when a person walks across a carpeted, dry room and touches a metal door handle. Since it is possible for a person a accumulate a static charge of tens of thousands of volts, it is important that the technician utilizes an ESD strap so that he is grounded and therefore at the same electrical potential as the equipment, where there is no danger of a static discharge.

A good set of micro-precision screwdrivers can be found in every electronic technicians toolkit. These are typically used to adjust variable resistors and capacitors, and to connect wires to proper terminals. Where micro screwdrivers are normally used in a low-voltage setting, regular-sized insulated screwdrivers are used for high-voltage operations.
These are some of the most common tools that are used by electrical workers. There exists a plethora of different electrical tools and testers, but most of these are meant for a very specific task.
