Re: Voltage on Frame
the impedance of a Digital Voltmeter (DVM) is over a million ohms - so the 'short' would have to have millions of ohms of resistance - that is a possiblility -if someone spilled something on the breaker or ground, and it was salty or only slightly condutive, then you would see voltage on the frame with a DVM - but if the resistance is that high its not a problem
you can put your fingers on the probes of a DVM and it will register several thousand ohms - much less than the input resistance of the meter iteself when its on the volts scale.
