I was doing some reading on gfci's and they referred to a neutral to ground
short upstream of the gfci would trip it.
aren't the neutral and ground buss connected and wouldn't this be seen as a
short ?

am wiring a plug/cord into a new dishwasher for installation and I came
accross
a intersting ground nut.  It is like an inverted cup with feet sitting
against the back of the splice box with a nut running through the middle?  I

Just curious:
Every once in awhile, the subject of the super capacitors (FARADS of
capacity in a handheld container.)
I have seen caps sold at Best Buy for the super sized automobile sound

Does anyone have access to information on this vintage relay?

Any URL that has examples and exercises of
Digital electronics, Boolean Algebra,
Microprocessor Engg, DRAM design,
controller, register design, analog transistor

Hi all.  I don't know if this is the correct ng or not, but I thought I'd
try here.
I have a pump with an electric motor.  It has been running fine till a while
ago it started poping the breaker.  I verified that the pump impellor turns

hey im new to electrical installation and engineering so anyone got any
tips?

i know that i need a deep cycle battery for this and from what i can
tell there are a plethra of options as far as batteries goes to pick

Am looking for a good, read inexpensive, bench power supply. +-5, +-12,
0-20VDC, and 0-20?VAC. Has anyone ever used a PC powersupply for the bench?
Thanks,

I have several contactors with 24 VAC coils, but I need 240 volt coils.  
The coils are wound on a simple plastic form, and would be very easy to
rewind.  Is there a way to calculate what gauge wire to use and how many
turns, so it has sufficient pull-in force but won't overheat?

I'm interested in building a custom aluminium radiator for a little project
I'm planning but I haven't worked with aluminium too much so I have a quick
question. The design is going to be fairly straight forward with tubes and
fins but I need to know how to 'soldier' the fins. Is ...

I have a question that I can't seem to find the answer to, or even a
direction on.   On a generation system (GE in this case), there are
bus VT's configured in open delta - open delta and the B-phase of the
secondaries is grounded.  These VT's feed various meters, the

suggestions?????   Thanks Chris...

I've started a 15 HP (480 V, 3 phase) motor while running a similar 25
HP motor, and my  Onan 37 kVA generator with Ford 6 cylinder LPG
engine running at 1800 rpm only bogged for a short while, around a
second or so.  Even though the motors are never started under a
