500v IR test shock?

[Bailey326]

Why are you testing at 500V for this?

I normally apply a continuity test first, if it is above the max reading of that tester then I'd switch to the IR range but at 50V or 100V

The continuity setting of most MFT's doesnt have the range required, so the IR setting is used because it has a much higher range.

Yes my multimeter in continuity mode goes up to 19.99k and so then my next available option to get a higher range would be 250v.

Why do I see and read lots of people using it at 500v for this test?
I've never liked the idea of doing this.

Probably because so many people have been taught "all IR tests at 500V" without teaching any of the thinking behind why you might use a different voltage in some situations. And because most of these situations are fairly modern, it's become on of those unwritten "laws" passed on from generation to generation of new leckys.

You're supposed to warn anyone present before carrying out an insulation test to prevent them from receiving a shock.

Or if your at college, attach the leads to your mates ears

Unless it's the kitchen fitter who put a screw through your cable.
