Most trendy PAT testers have a helpful IEC lead take a look at facility. All one has to do throughout PAT Testing is to plug in each ends of the lead and take a look at Earth Continuity, Insulation Resistance and Polarity. The Polarity take a look at simply checks that the lead is wired accurately. This will solely be carried out if one has entry to each side of an influence wire.
On different PAT testers there’s a facility for a 2-stage take a look at of energy leads. The primary stage is a take a look at of Earth Continuity and Insulation Resistance by plugging each ends of the lead into the PAT tester. The second stage is a test of the polarity by plugging the facility lead into the mains and the opposite finish to the tester. Couple of lights on the PAT Tester present whether or not the polarity of the facility lead is right or unsuitable. Car MP3 Player B08BP3PTCL
PAT Testers that do not need this facility can use an influence lead tester that’s out there as an adjunct. That is utilized in a 2-stage take a look at.
Stage 1: The lead is plugged into the PAT Tester and the lead tester. The take a look at lead is clipped onto a submit offered on the IEC lead tester and the Earth Continuity and Insulation Resistance take a look at is carried out.
Stage 2: The ability lead is now plugged right into a mains socket and likewise into the IEC lead tester. The 2 lights on the tester present whether or not the polarity of the IEC cable is right or defective.
When PAT testing lengthy IEC leads one wants to recollect to regulate the go limits as outlined within the IEE Code of Follow.
PAT Testing Mains extension leads
If a PAT Tester has an IEC lead take a look at facility, then this may be simply tailored to check mains extension leads as properly. All one wants is a brief IEC result in join the socket of the mains lead again into the PAT tester as proven. The same technique will also be used if the PAT Tester has a 2-stage IEC lead take a look at.
