    Find prospective cabling positions using a variety of resources.

    Organize potential positions into categories.

    Discover possible educational directions for future opportunities.

    *vervie,:

    In order to locate prospective job opportunities, the student must be familiar with

    the different methods of locating cabling-related positions.

    here are many different types of available cabling jobs from an entry-level

    !able Installation echnician to a !abling Installation "roject #anager. In

    addition, there are a number of advancement positions such as cabling mar$eting

    representatives, estimators, and design engineers to name a few. his lab gives

    the student the s$ills to research available job positions, determine where their

    e%perience and s$ill sets lie within the job mar$et, and plan future opportunities

    and goals around their education and interests.

    he blac$ or red wire is the ungrounded, or hot, conductor. his is the conductor

    that feeds power to an appliance.

    he white wire is the grounded, or neutral, conductor. It is the electricity path

    bac$ to ground, which completes the circuit.

    he green, or bare copper, wire is the grounding conductor. It is an e%tra safety

    wire that provides an additional path to ground which is normally connected to

    an appliance housing.

    !urrent normally flows between the ungrounded conductor, or hot, and thegrounded conductor, or neutral. !urrent flows through the grounding conductor

    in the event of a fault.

    + multimeter is an electrical testing tool capable of detecting voltage levels,

    resistance levels, and open or closed circuits. It can measure both +lternating

    !urrent 0+!1 and Direct !urrent 0D!1 voltages. Opens and shorts are shown by

    the amount of resistance for each circuit type. Opens are very high resistance and

    shorts are very low resistance. his resistance is measured in ohms.

    Direct !urrent is a voltage at a certain level that stays at that level flowing in one

    direction. + battery produces D! voltage. One battery terminal is positive and

    one is negative. 2hen a load such as the light bulb in a flashlight is connected

    between the terminals, electricity flows through the filament in the bulb causingit to glow.

    +lternating !urrent is a voltage that rapidly changes between positive and

    negative. +n e%ample of +! is the common wall outlet. In most countries, this

    outlet provides either 889-8:9; +! or ?1 use 889-

    8:9; +! in all of the outlets.

    Step 1 C(tti"g &oo.s

    6andle all of the tools listed. *imulate how they would be used in the field.

    9iago"a. C(tti"g -.iers

    Diagonal cutting pliers, also referred to as side cutters, are used for cutting I*O-

    D 0!ategory >e1 cables and other small to medium copper cables such as 8>-pair

    cable. hey can also be used to score the jac$et of a cable. hese cutting pliers

    should only be used for cutting copper. !utting steel wire will dull the blades

    rapidly.

    !are should be ta$en when using side cutters. 7esides the obvious hazard of

    cutting fingers, it is possible to get fingers pinched between the handles.

    *afety glasses should be worn when using this tool. 7its of cut wire could fly up

    into the eyes when cutting.

    Li"ema"s -.iers

    &inemanEs pliers are used for cutting larger copper cables li$e 8>-pair cable.

    hey can also be used for cutting smaller steel cables. &inemanEs pliers have a

    large heavy head. he pliers can also be used for pounding. *tudents should ta$e

    care not to pinch their fingers or cut themselves when using linemanEs pliers. +s

    with all cutting tools, safety glasses should be worn.

    -a"%(it ;ire Stripper &oo.

    he "anduit wire stripper tool is used to remove the outer sheath from twisted

    pair cable and small coa%ial cable. he tool is pulled apart to retract the cutting

    blade. !able is inserted into the hole and the installer releases the blade. he tool

    is spun around the cable one turn. It turns in a cloc$wise direction for cables

    with thinner jac$ets and counter cloc$wise for cables with thic$er jac$ets. hetool is then spread apart to remove the tool. he jac$et can now easily be pulled

    off. 7ecause this is a cutting tool, safety glasses should be worn when using this

    tool.

    $.ectricia"s Scissors

    lectricianEs scissors, also $nown as snips, can be used for cutting twisted pair

    cable and miscellaneous wire on an installation project. here is sometimes two

    notches on the bac$ edge of one of the blades. hese notches are used to s$in

    insulation from individual conductors. he scissors can also be used for scoring

    cable jac$ets. +s with other cutting tools, care should be ta$en not to pinch

    fingers between the handles or cut fingers. +lways wear safety glasses when

    using snips.

    he utility $nife is used for any number of tas$s where a razor blade is needed.

    he blade on this tool is razor sharp and can create very deep wounds. +lways

    use great care when using this tool to ma$e sure hands and fingers are $ept away

    from the blade. *afety glasses should be worn when using this tool. Only push

    the blade out when cutting material. +s soon as the material has been cut, retract

    the blade bac$ into the handle. +lso, always ma$e sure the blade is loc$ed. +s$
