TITLE:- PRELIMINARY ELECTRICALCHECKS

Before carrying out preliminary electrical checks , ENSURE there is NO VOLTAGE at the appliance using an electrical test meter .

EARTH CONTINUITY CHECK Appliance must be electrically disconnected , meter set on Ω ( ohms ) scale . Test leads from all appliance earthed metals to earth pin or plug . Resistance should be less than 1 Ω ( ohm ) . If the resistance is greater than 1 Ω ( ohm ) then check all earth wires for continuity and all contacts clean and tight . If resistance of earth is still greater than 1 Ω ( ohm ) then this should be rectified r ectified by a electrician .

SHORT CIRCUIT CHECK Appliance electrically disconnected . All switches ON ( including stats ) . Meter set on Ω (ohms ) scale . Test leads from L and N in appliance terminal strip / block , if i f meter reads “ 0 “ then there is a short circuit .

EARTH CONTINUITY :If the resistance between the earth pin of the plug and the appliance case is greater than 1 ohm (Ω ) check all the earth wires for continuity and that all the contacts are clean and tight. If the resistance to earth is still greater than 1 ohm ( Ω ) then the fault must be rectified before proceeding . WARNING, Poor, or no earth continuity will cause a danger if there is a short circuit on the appliance, as supposedly earthed metal would become LIVE giving rise of an electrical shock when touched.

SHORT CIRCUIT TEST :-

The resistance between L and N indicates the internal resistance of the appliance. Where this is zero ohms, there is a short circuit fault which must be rectified. If a fuse repeatedly fails, but no fault is indicated in this test, a detailed continuity check ( i.e. by disconnecting and checking each component ) is required to trace the faulty component. It is possible that fault could occur as a result of local burning / arcing, but no fault is found under test. However, a detailed visual inspection should reveal evidence of burning around the fault.

RESISTANCE TO EARTH CHECK :All switches, including any thermostats, should be switched on. If the resistance between L and E is other than infinity ( ∞ ), there is a fault which should be isolated. A detailed continuity check is required to trace the faulty component.

MAINS VOLTAGE AND POLARITY CHECK ( TESTS PARTS 1. 2. 3 ) :If a low Vac reading is given between terminals L and N or Land E, there is an electrical fault. Repeat the test at the appliance plug / inlet spur to check the wiring system up to the appliance and rectify any fault. If necessary, repeat the test at the supply system socket outlet / spur. If the fault also occurs at this stage, then there is a house system fault. This should be rectified by a competent electrician, such as a NICEIC registered contractor. The appliance should be left disconnected and the customer warned not to use the appliance until this work has been carried out.

MAIN VOLTAGE AND POLARITY CHECK CONTINUED :- Part two Most appliances will appear to operate normally with the live and neutral connections transposed. The exceptions are some models with spark generators or microprocessor controls. However, if there is a short to earth, the fuse would not blow and the resulting current flow could cause a fire. In addition, most switches are normally connected in the live circuit and transposition of the live and neutral would mean the appliance was still ‘on’ when apparently switched ‘off’. Transposing live and earth connections should cause the fuse to blow. It would also cause the appliance to become live if there was a fault in the earth circuit. Transposing neutral and earth would not prevent the appliance from working, but is contrary to the electricity supply regulations and must be avoided. On some installations it would cause the earth trip to fail.
