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
