When I was young I worked in a music store (surprise  :lol: ) and one summer the air handlers in the mall shut down.  We got some large floor fans to circulate air.  I went to move them while they were running.  I grabbed one and went to get the other one.  As I grabbed the second one I became immediately aware that one of the plugs had been replaced without following color code with a non polarized plug.  I couldn’t let go.  My boss saw what was happening and quickly unplugged one.  I think he saved my life that night.


Which is essentially the same thing as using some kind of cheat to force a polarity change on a polarized plug.

I rest my case.

For safety purposes the safety ground should be big enough to carry the full capacity if the circuit. Unless it can handle the fault current when a phase to chassis fault occurs, this wire will most probably overheat and possibly even fuse.

The National Electric code recommends on Table 250.122 that for a circuit connected to a breaker of up to 30 amps the size of the safety ground wires should be the same as the current carrying conductors for a given breaker size. So unless the gauge of your IC wire is equal to or greater than that of the power cored connecting the unit you are running  a risk by relying on the IC to provide a a safety path to ground.

And this of course assumes that the return of the IC circuit is designed to be at earth potential and it is not a floating ground circuit in which case the IC cable would not have a earth path in the first place.

  OK Experts. What is wrong with components ungrounded except one [ Amp] to a grounded power conditioner. Are not the components grounded through interconnect ?
  Esplain.

  Interesting Jim. For me glare is a bad thing due to a eye surgery gone wrong. So the darkening was a blessing. Valid point for others to consider.

  Yes Sirre Bob. Clean connections do wonders for the high frequencies. Cable management is important as well. Should not touch each other. Power cords away from signal cables.
  Have fun Jim sorry I cannot make it doing demos.

Yes, sirs!  Failure to follow electrical protocols is just stupid when one has no idea what is the safe way to proceed.

Two personal cases here:

When I was young I worked in a music store (surprise  :lol: ) and one summer the air handlers in the mall shut down.  We got some large floor fans to circulate air.  I went to move them while they were running.  I grabbed one and went to get the other one.  As I grabbed the second one I became immediately aware that one of the plugs had been replaced without following color code with a non polarized plug.  I couldn’t let go.  My boss saw what was happening and quickly unplugged one.  I think he saved my life that night.

I worked in implant at Philips Semiconductor until they pulled up stakes in America.  Implanters back then pulled vacuums in the -8 torr range, developed huge magnetic fields, produced ionizing radiation, ran on poisonous gasses and voltages up to 1,000,000 V.  To top this off there was the source.  An implanter is essentially a single car garage.  The source arc is the filament.  Variable voltages from about2 - 25VDC at currents up to 250A.

I was on the ERT (emergency response team) and I saw the results of a moron (rest his soul) that did not follow strict lock out/tag out (LOTO) protocols.  It is something I will never forget.
