hello can someone tell me if this will get me through this question to decribe how to undertake an insulation restence test on a new installation
or is this over kill lol
describe how to undertake an insulation resistence test on a new installation
inform people in the area
seek permission to isolate the supply
lock off the supply
prove the installation is dead useing an approved voltage indicator
confirming the approved voltage indicator is working correctly with the use of an proving unit
then test the approved voltage indicator again with the proving unit after confirming the installation is dead
warning notices are present
remove all voltage sensitive equipment
like lamps dimmers neon lamps control timers delay timers luminairs
select an insulation resistence tester check calabration of insulation resistence tester
check for signs of damage confirm with GS 38 document
check leads and probes for signs of damage
leads should be insulated with no damage to leads
leads should be correctly coloured
probes should be fused 500A
probes tips should be shrouded
probe tips should be atleast 4mm diametre preffably 2mm
set insulation resistence tester to 500v dc
with circuits breakers and switches open
test between line conductors and neutrel conductors connected together to earth at the appropriate distrbution board or for circuits not vunrable to insulation resistence testing line and neutrel seperately to earth
for circuits containing 2way switching and intermedate switching the switches must be opperated one at a time and circuits subjected to addtional insulation resistence tests
an insulation resistence value of not less than 1.0Mohm complies
with the regulations where an insulation resistence of less than 2Mohm
is recorded the possibility of a latent defect exists in these cirumstances each circuit should be tested seperatly
or is this over kill lol
