Two Question on Fuses
Two Question on Fuses
(OP)
I have had these two questions purposed to me. I have very little back in electricty and hoping that this form can give me an answer.
1. One lead of a volmeter is connected to one side of a fuse and the other lead to the other side of the fuse. What is the significance of a 120V reading?
2. If a voltmeter is used to measure the voltages between the load sides of three fuses in a three phase electronic motor controller and the readings all are aprox. 480V AC, what can we say about the three fuses?
Thanks for the help

If you are reading a voltage across a fuse the fuse is open (bad).
As for question 2 I'm not sure. It depends what your load is. You would still read a voltage even with a blown fuse.

I am not sure we can tell who you are rattling the saber at, when your wording is:
"Sounded and smelled like a home work" (question?)
and then . . . .
"too correctly contstructed electrical question" Does the "too" mean also, if so, what does this mean? If it was "to", then I still am not certain what you mean. If "two", OK, but try to spell things right, before you start threatening. It has more style.

There's a third interpretation which might be substituted with 'suspiciously well' in the sense of the phrase used, meaning 'too correct' to be believable. That was how I interpreted the comment.
