All I use in a Meggger MIT 200, it's only a 500 volt unit, and I only use it for trouble shooting
OK thanks I am looking into the
MIT 400 series. Looks like it has Bluetooth wireless data transfer. I would prefer USB. Looks like it can only do a 1000V test. not a 1080. Thats probably fine.
and a rugged design.

..going in another direction with the reference to article 550, and a mention of manufactured buildings.
Yeah sorry the reference to mfd buildings was sloppy, just the test is all. The test is a nice compromise because it is in a familiar book for the AHJ.

OT, but how do they test K&T wiring that is free air installation then put insulation around it and even consider it safe?
Agreed. Here is a link to the
Oregon's NEC amendment. Scroll down to 918-305-0180. I don't remember what type of wire that K&T rubber conductor is. I thought it was just R.I had an old 1930's book "California electrical regulations in the workplace" that had a 310.16 type table. It listed it as 80C insulation. The Oregon amendment changed that to 60C. I don't understand why it is not enforced to be on a GFCI breaker during panel change (410.18 and 406.3(D)(2) 2005 NEC) I often do this on a panel change if I see 3 prong replacements or new light fixtures in a house on K&T or ungrounded wiring.
Customers don't like the cost though.

There are many times that even a megger will not show damaged conductors..
Agreed! That is why I have not purchased one of these yet. I have done fine with the Ideal Suretest and visual inspection.
