Theory of Operation

Thetracerconsistsofatransmitterandareceiver.Thetransmitterproducesaunique

signalontothecircuittobetraced.Thereceiverdetectsthisuniquesignalwhenplacedin

theproperorientationtothewiresbeingtracedorbreakersbeingidentified.Thereceiver

providesanumericvalueandavariablepitch/tonethatincreaseasthesignalbecomes

stronger.

Thetransmittersendsa32kilohertz,fixed-amplitude,time-modulatedsignalthatinjectsa

voltageontothecircuittobetraced,whichtheninducesanelectromagneticfieldontothe

circuit.

Whether the circuit is open or closed greatly affects the strength of the electromagnetic

field.

Inanopencircuit,nocurrentcanflow,sotheelectromagneticfieldproducedismuch

weaker.However,inaclosedcircuit,theinjectedvoltageinducesacurrentflow,which

producesamuchstrongerelectromagneticfield.Thisistheoptimalmethodfortracingas

thismuchstrongersignalallowsthereceivertodetectitfromagreaterdistanceawayfrom

thecircuitbeingtraced.

HerearesomeexamplesofOpen/ClosedCircuits:

RemoteReturnPath

Electromagneticfieldsradiatecounter-clockwiseinrelationtothecurrentflow.For

example,currentflowsoutonahotconductorandreturnsontheneutral.Thischangein

oppositecurrentflowalsocreatesopposingmagneticfields.So,whenthesetwoopposing

conductorsareclosetogether,thetwomagneticfieldstendtocanceleachotherout.This

cancelingeffectdiminishesthecircuit’sabilitytoradiatethetransmitter’sstrongsignal

makingitmoredifficultforthereceivertodetectthesignal.

Toavoidthecancelingeffectoftheopposingmagneticfieldsandoptimizethe

transmittedsignal,theconductortobetracedshouldbeseparatedfromthereturn

conductorbyutilizingaremotereturnpath.

Thesimplestmethodistousethe25’testleadtoconnecttoaremotereturnpath,such

asaneutralorgroundfromanothercircuitorawaterpipe.Whenidentifyingbreakers,

thehotandneutralarealreadyseparatedattheelectricalpanelsotheuseoftheAC

outlet adapter is sufficient.

Ifunsurethattheremotereturnpathchosenisagoodone,useamultimetertomeasure

theresistancebetweenthecircuitneutralandtheremotereturnpath.If>100Ω,a
