I have a ten year old KitchenAid (KUDS24SE) dishwasher for which I have just

I am looking for a good introductory book on power systems: I will be
responsible in a few months of a medium voltage power system for an
industrial establishment. I am an electronic engineer, i.e. I have good

Dumb question:
Does the NEC specifically allow, forbid or is silent on the subject of
soldering home electrical wiring (type NM solid copper) together before
using wire nuts?

I have an '88 Kawasaki 600R motorcycle.  It has an electronic 'brain'
that seems to determine when ignition occurs and spark advance.  The
only input this brain receives is from a pulsing coil (part 59026 in

I was looking at a USB cable and I noticed a black cylinder, about 2cm
diameter, just after the connector on each end of the lead. I was
wondering what this is?
Thanks
