Hi, I got snuckered into putting together a diverse set of pc boards +
devices as part of what is supposed to be a software project. I'm
going to deliver with a big disclaimer that I ultimately don't know
what I'm doing, but I was wondering if anybody had some quick answers
for some hopefully simple questions.
1. Are there any safety guidelines for hooking a device up to 110 VAC
current? Is this a matter of just making sure the connections are
insulated and properly grounding anything that might come into contact
with a stray voltage? I need to hook wall current up to a 24 VAC
transformer that will drive a stepping motor via a 3rd party pc board.
There are a couple of other boards that get their power from a
computer.
2. Any links or info on specifying a fuse? I have 24 VAC at 2 amps,
so that would be something like .6 amps for 110 volts? When should I
use slow blow fuse?
3. Is it all right to mount everything on metal box with a few vents
and close it up? 24 volts at 2 amps is about 50 watts. It seems like
I could put a 60 watt light bulb into a box and close it up no
problem. Is that the case?
4. Any good books on this topic? When I was a student (a while back)
"The Art of Electronics" by Horowitz and Hill was popular. It seemed
a bit "off balance" in that in one sentence they were telling you not
to use electrical tape to insulate connections and in the next
sentence they were talking about quantum electrical theory. Is the
new edition any good? Any better books?
Thanks.
