How will you be measuring differential leakage and touch leakage?

I thought PAT testers were introduced so that semi-skilled guys could test appliances rather than using an electrician. The testers have a lot of nice extras and can make recording the results easier. But any decent electrician with a insulation and continuity tester plus a note book can test appliances.
How many battery powered PA testers do that ? At my last job (in IT), the boss thought it might be a good idea to get a tester and offer it as a service to customers. My response was that I wasn't going to be the only person "qualified" to do it, and no-one else actually bothered. I borrowed it and used it for my own requirements more than it got used at work (I'd test stuff that came across my desk) Anyway, the spec for it wasn't for much current - only something like 200mA IIRC.My biggest issue would be with the 200mA continuity test. 25A will prove the cpc far more effectively (or nuke it if it's hanging on by a strand or two).
I prefer the mains-powered PAT Testers. Mine can be connected to either a 230V or a 110V supply.How many battery powered PA testers do that ?
If 200 mA is good enough for installation continuity testing, why not not for appliances?I'd been thinking about making an adapter a bit like that - but with an extra socket for an earth continuity lead and a switch. Idea being that the switch would take care of the different connections needed - so the MFT could stay connected, the extra lead connected to exposed conductive parts for Class I continuity & Class II IR test, and only the switch would need to be moved (plus the mode switch on the MFT).
Otherwise, yes an MFT can be used, it's just a bit of a faff having to reconfigure the leads all the time for the different tests.

The flex in an appliance would typically take more abuse than fixed wiring embedded in the walls or in a conduit/trunking to be fair. It's not really a like comparison. Although traditionally conduit joints would have been tested at these higher currents.If 200 mA is good enough for installation continuity testing, why not not for appliances?
You don't need to be qualified to carry out ISITEE.I'd been thinking about making an adapter a bit like that - but with an extra socket for an earth continuity lead and a switch.

Why doesn't the all-purpose glue stick to the tube?
Not required. Earth Bond 4V at 100mA min and IR 500V DC at 1mA max. are the only compulsory tests. The rest are more to do with analysis...How will you be measuring differential leakage and touch leakage?
