440 volt question

[kwired]

I glazed over most of the thread when I saw you are using a meter not suited for more than 277V on a circuit that could be 480VAC. Do yourself a favor as many in this thread have suggested.....spend a few more dollars on a 600VAC meter. I have seen meters (mostly the very cheap ones) explode in the user's hands due to overvoltage. At the end of the day, someone, somewhere is waiting at home for you......

Usually happens when it is set to measure resistance and they connect it to voltage.

Usually, but not always.

A friend had just taken his meter out of his vehicle and it was cold outside. When he came in, the meter got condensation in it. He went to test a 240 volt res panel and the meter exploded.

It was a cheepie, and not CAT rated.

He now knows what the CAT ratings mean. Lucky he learned the hard way and not the real hard way.

I thought 440 is obsolete. It's still used????

I said "440" in my original post, but what I meant was 480.
