Begginers questions

Ben, think you may be confusing yourself a bit, here goes


Earth Continuity - For Class I appliances, the test is to ensure that the connection between the earth pin in the plug of the appliance and any exposed metal casing of the appliance is of sufficiently low resistance.

Readings should show less than 0.1Ω + R1 (where R is the resistance of lead)

Insulation Resistance - This test is used to verify that adequate insulation exists between the mains supply pins and the earth.

Results should be over 1MΩ for Class I and 2MΩ for Class II

Hope this helps and makes sense

Thanks mate,

I think you might be right in the sense of me confusing myself

I think one of the problems is that im learning to many things at one time and just mixing it all up!
