Buy a unit with both 1 AND .5kV ranges. It would be money well spent on a tester with built-in 600VAC measurement, to be damn sure the circuit’s deenergized before trying to meg. [Escaping smoke is expensive.]

Biddle/AVO's "A Stitch in Time" booklet is excellent reading. Also stuff at: http://www.avointl.com/us/publications/Index.asp
