12Fault FindingPreliminary Electrical SystemsCheckA. EARTH CONTINUITY CHECK - Appliance mustbe electrically disconnected - meter set on Ω(Ohms) x 1 scale and adjust zero if necessary.a) Test leads from any appliance earth point to earthpin on plug. Resistance should be less than0.1 Ω (Ohm), check all earth wires for continuityand all contacts are clean and tight.B. INSULATION CHECK - Appliance electricallydisconnected, all switches ON.a) meter set on Ω (Ohms) x 1 scale.Test leads from L to N in appliance terminalblock. If meter reads «0» then there is a shortcircuit.b) meter set on Ω (Ohm) x 100 scale.Repeat test with leads from L to E. If meter readsless than ∞ (infinity) there is a fault.NOTE - Should it be found that the fuse has failedbut no fault is indicated - a detailed continuity check(i.e. by disconnecting and checking eachcomponent) is required to trace the faultycomponent.It is possible that a fault could occur as a result oflocal burning/arcing but no fault could be found undertest. However a detailed visual inspection shouldreveal evidence of burning around the fault.STARTIsolate applianceand carry out:A: Earth Continuitycheck.Has inlet fuse blown?Carry out:C: Polarity check.Electricity supplyshould now besatisfactory.Carry out:D: Resistance toEarth check.Inlet wiringfaulty.Rectify anyfault.Isolate appliance andcarry out:B: Insulation check.Rectify any faultincluding replacingfuses as necessary.SOCKET(face view)PLUG (with coverremoved)Earth WireGreen/YellowNeutral WireBlueBrown BlueGreenYellowBrownBlue( )FUSE( )EN LNO YESNO YESA.
