How do you measure 3 phase 440 with one hand?

[Tim McCulloch]

I want a prehensile tail with an opposable thumb....

How do you measure 3 phase 440 with one hand?

Very, very, carefully! (I seem to recall that was the punchline to some joke when I was a kid, but can't remember the set-up )

How do you measure 3 phase 440 with one hand?

I dunno. That's my Lampie's problem 

Ya, that's a nasty shock (or worse) just waiting to happen...

How do you measure 3 phase 440 with one hand?

The question answers itself.

With one hand (and the other safely behind your back).

[Steve-White]
