really? .89c ground lifters?

The following paper, by Bill Whitlock of Jensen Transformers, presents a good explanation of why equipment connected via unbalanced interfaces (i.e., rca cables) is inherently prone to the kinds of problems that have been mentioned, and presents some approaches to dealing with these problems that do not involve lifting safety grounds:

As an Electrical/Electronics Engineer, I am telling you that lifting the ground and you become a better ground than the house ground and electricity will take the easiest path to ground and that becomes you.

Say what? Please explain how the human body can be a ground for an AC grounded power system......

Also, the load in your home should be balanced on each phase. Having all of your high power equipment on one phase will overload the wiring, cause it to heat up (IxIxR) losses and cause the insulation to fail causing a major electrical fire.

We are talking about audio equipment here.... In most cases all the combined connected loads would only add up to around 8 to 10 continuous FLA at best... Most hair dyers pull more than that.

the human body is an impedance. resistance, inductance and capacitance. You have an impedance. If there is a system fault or a lightning strike, or some such, very high voltages can pass through the equipment through you to ground. Since you lifted the ground, you become the easiest path to ground. We are not talking about audio equipment. We are taking about electricity, voltages, sometimes very high voltages, current and impedances. a blown transformer and you have very high voltage spikes, a shorted device or a failed tubed device and very high voltages hit you passing very high currents through your body. Since you are an impedance, small but there, you will draw very high currents.

Simply electronics/electricity rules.

enjoy.

That is a lot different statement than the one I quoted of yours in my previous post......
Yes if any part/s of the body is placed between a difference of potential, current will flow through the contact points. If the voltage and current is high enough there will be electrical burns at the entry and exit points. And yes it can kill you deader than dead! In the case of a ground fault the current is non discriminating.... It will take any conductive path available to get back to the source. It likes the least resistive path but it will still take any available path.

You really need to go back and read my other responses to this thread.....

I understand what you are saying. However, in terms of electrical design and safety and codes, you never, never, never lift grounds. If there is a problem, hum, ground loops, etc. isolate the faulty piece of equipment or cable and fix or replace it. Like I implied earlier, all you need is for it to happen once for you to realize what a bad mistake you made by lifting the ground and compromising the electrical safety. That is, if you are still alive to talk about it. It may not be you. It may be a child or guest. I have experienced ground loops and hum before. I took the time to isolate the faulty equipment and fix or replace it. I'm very much into great music and accurate, detailed reproduction of the signals, but not at the cost of safety. Life is short enough as it is. I don't mean to rain on anyone's parade but, cutting corners and shortcuts are not the proper way. One should never advocate compromising safety.

Enjoy
