TESTING POWER LEADS AND MAINS EXTENSIONSPower leadsMost modern PAT testers postulate a handy IEC lead test adeptness. plenary unrivaled has to deliver is to plug in both ends of the lead and test Earth Continuity, Insulation barretter besides Polarity. The oppositeness objection just checks that the make active is wired correctly. This can only be done if one has access to both sides of a power cord.On other PAT testers practiced is a facility because a 2-stage test of power leads. The first stage is a test of Earth Continuity and Insulation resistance by way of plugging both ends of the lead into the shade. The second stage is a check of the polarity by plugging the power lead into the mains also the single end to the tester. Couple of lights on the PAT canopy show whether the polarity of the power lead is correct or wrong.PAT Testers that do now not posit this facility boundness use an power lead tester that is available as an accessory. This is used in a 2-stage test.Stage 1: The lead is plugged concern the PAT Tester and the lead baldachin. The test lead is clipped onto a post provided on the IEC motivate tester and the cave Continuity and insulation Resistance test is carried out.Stage 2: The expertise lead is now plugged into a mains socket and additionally into the IEC lead canopy. The two lighting on the tester show whether the polarity of the IEC cable is desired or faulty.When testing wanting IEC leads one needs to be aware to conclude the pass limits as outlined in the IEE judicature of Practice.Mains extension leadsIf a strong-willed shade has an IEC lead test facility, then this can mean easily adapted to dare mains extension leads as really. All one needs is a short IEC lead to connect the socket of the mains lead back into the PAT tester over shown. A similar approach can also be used if the PAT cope has a 2-stage IEC institute test.PAT Testers that do not have an IEC lead defiance facility at all can use the IEC lead tester. This is used in a 2-stage test through outlined below.Stage 1: The mains lead is plugged into the PAT cope besides the brief IEC go into is plugged into the mains lead and the IEC lead tester. The test lead is cropped onto a post provided on the IEC lead tester and the Earth Continuity and insulation Resistance threat is carried out.Stage 2: The mains extension lead is now plugged recreation a mains socket. The short IEC activate is plugged into the mains also into the IEC lead tester as shown. The two lighting on the cover show whether the polarity of the mains extension is correct or faulty.When trying out mains leads, please note the following:ₘ Depending on the length of the extension lead, adjust the Earth continuity pass limit.ₘ On a multi-way mains extension, it is finance to concur every outlet in that true lair continuity. If any one socket should ignore then the whole extension bring about must be failed and discarded.ₘ If the Insulation Resistance trial is carried out at 500V, then one consign seal a fail if the unfolding lead has surge protection. In this case use a 250V test if one is available on the tester. If this is not available thence open a suitable note in the test record and pass the appliance. Some testers such as the BattPAT from First axe Safety do now not have this problem as the Insulation Resistance test is always done at a voltage of 350V.ₘ irrefutable is central to un-reel any coiled produce leads to inspect for any damage to the cable prior to any testing.ₘ Long up leads have a higher power rating when un-coiled compared to when they are frizzy. If carrying out the Earth Continuity test at a current of 25A, care needs to be taken not to perfect this over a long period as this capability lead to over-heating. Normally resolute testers zero this to 5 seconds which should not present a problem.ₘ some extension leads may have an RCD built agency. If this is the case, please refer to Test Examples 8 when wearing extrinsic the tests.Users of proliferation leads must be fictional conscious of the following:ₘ enthusiasm extension leads take it a higher ability rating whilst un-coiled compared to when they are coiled. If the person intends to use the extension lead to power say a 2kW heater, then intrinsic is very important that it is fully uncoiled. If it is not coiled, so there is a risk of a phlogiston breaking out.ₘ An extension lead wired secrete normal 13A news flash should not be longer than 12 meters. ₘ An extension lead must not be plugged into another extension lead twin that their total length exceeds 12 meters.ₘ If the extension lead is longer than 12m, then it must be fitted with a Residual routine Device (RCD) with a rated operating current not exceeding 30mA.ₘ Care need to be taken to route the extension lead away from work areas and no longer across paths where they might get awakened and pulled, or run over and damaged.
