Q: Will these read the ac output from a 12vdc to 120vac modified sine wave inverter (ie - does it read rms value)? thanks in advance!

Not likely. The premium feature you're asking for is called a "true rms" volt meter. Simple AC volt meters assume a sine wave and display 0.707 of the peak voltage. True RMS volt meters take many samples and compute the RMS voltage. Some require a repetitive waveform, all have an upper limit on the waveform slope before the accuracy degrades. The modified sine wave converters usually produce a staircased approximation of a sine wave. The summit area is usually a bit flat-topped which makes a peak reading volmeter understate the RMS voltage.

Q: I am looking to measure the output voltage of a Variable frequency drive three phase no neutral circuit what are the recommendations to wiring

Bien yo los estoy usando sin el neutro porque estamos usando el voltaje a 220 voltios y los medidores trabajan perfectamente exigen a 120 voltios y a 230 voltios yo compré de 230 voltios

Q: What size standard drill bit is needed to drill for these?

a 7/8" hole will work it is designed for a 1/2" knock out
