Dear Experts,
I have some trouble with NEC grounding code provisions. I've been doing
this for a long time from Electrical Plans of different Design
Companies for industrial plants & comm'l complexes even in power staion

So I just installed a new garage door opener, and somehow taught it how
to recognize the two transmitters that came with it. The instructions
assured me the openers would somehow 'roll their code' each time the
door was opened as a security measure.

Please tell me about the factors to be considered for earthing

Thanks for guidence on PLC information.
I searched the web for I/P converter and P/I converter working concept.
all results came with product catalogues.
Can anybody help me out,

A good one tonite.
Power went off for a few seconds and then came back on at between 175
-190 volts for nearly 3 hours. The farm next door lost two phases
completely, apparently had the same wandering and low voltage on the

Dear Experts,
I'm in the mountains doing installation of a substation grounding in
Thailand, after 15 years of labor suprvision on construction works and
rote following of plans has really blunted my engineering/math analysis

Hello, I was wondering if someone could help me in building a variable
current source, which can run from a 9V battery, that can supply
4mA-20mA.

I am cleaning up an old 20 quart mixer to sell.  The power cord was
frazzled.  No apparent ground wire connection.  Insulation was off one
of the wires coming out of the capacitor holder, and sparks once about
four inches away near a spade connector (noticed the spark before the

I have completed the online Table 310.16 wire size, ocpd, and voltage
drop calculator.  I can't find anymore bugs but maybe you can.  It took
me about 10 weeks during the last 10 years to build this program.
It is at

Hello experts:
I am hoping to get instructions on the proper use of a megohmmeter in
the testing of a 3 phase 460 volt  29 FLA AC motor.  The motor in
question has been blowing fuses on an intemitent basis for a couple of

I am using Vishay 120 ohm Strain Gauges, (specifically EA-06-062AP-120)
to try and generalize certain readings taken from aircraft engines. We
have set up a small device to vibrate to simulate an engine on a small
scale.  The strain gauge is mounted to this device and the leads are

Hello Friend,
Today i just want to ask you one question.
What are the current nonconventioal methods of Power Generator.
I know about Power Generated through Solar Cell,
