I'll 'fess to it.
Of course, I work primarily with 110 - and I only work hot on a very rare basis. Usually just changing a receptacle, switch, or some such, and only where there's a single conductor in the box.
Multiple "hots", or >110? Kill 'em. Kill 'em all. Just got an Ideal 61-090 voltage / continuity tester on clearance at Grainger, and it replaces 3 smaller testers I used to tote around (Non Contact Voltage presence, high voltage up to 600VAC/200VDC, low voltage as low as 24VAC/6VDC, and audible continuity)
Tried to import pic, but couldn't.
