really? .89c ground lifters?

I again want to reiterrate that removing grounds is not only unsafe, it is irresponsible and the potential is not for electric shock, but for death. People are minimizing what could happen here. 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. There are many ways posted to find the faulty equipment. Please do so and fix the problem, do not lift grounds. Remember, "Accidents" happen when you do not expect them to. Lifting a ground in my opinion and getting severely shocked or causing a death is not an "Accident" you were asking for it by lifing the ground. 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. Imagine having one outlet or several outlets in series back to the panel on one phase. You now have a 10, 12 or 16 gauge wire w/neutral caring all that current. Is that wire rated for the maximum amount of your equipment? If not, no electrician worth their salt would allow this. Having your equipmen balanced on each phase is the proper way and having several independent outlets run to each phase with their own neutrals is the proper way. Example would be if you have mono amps for your speakers. One proper way is to have separate outlets for each amp run back to the panel and another outlet run to the panel for the lower powered equipment (pre-amp, turn table, tuner, cd player, etc., which should be combined via a conditioner, or multiple outlet device.

Enjoy and stay safe

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:

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

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.....
