Is cheater plug safe with grounded monster power?

This gives a good explanation of what the problem is and why it exists, but it is mainly for AV systems. It does suggest starting with the amp only in the system. You will probably not have much hum. Then you add until you get hum. Guess what you then deal with the problem, which probably means ungrounding that component.

It also suggest plugging everything into one power strip. This is in effect star grounding and will usually cause no problems.

Tbg - responses in order of your questions:

No.

If you choose to play around with things electrical, you really should develop a better understanding about electrical standards and construction of the equipment you are playing with. Your assumptions may kill you. A chassis does not have to be referenced to ground if it is insulated. It's designed designed to prevent the chassis from becoming "live" if there is a ground fault. In this type of design there is no need for a ground prong. A chassis that is referenced to AC ground needs the ground connection; if it is removed and there is a ground fault, the chassis can become energized and deliver a potentially fatal shock to someone who touches it.

Isolation transformers and a properly-constructed star ground. This is what I did in my home theater. No "cheater" plugs necessary. BTW, I didn't try to pin any sarcastic labels on you. Why do want to start that kind of childish crap?

Circuit breakers will not stop an electrical fire. Circuit breakers will not prevent ground faults.

"STUPID, STUPID" Your statement prompted my dismissal of your condecenson. One of my undergraduate majors was EE, so don't lecture me.

None of the component that I refer to have plastic housings, so forget that assumption.

"if (the grounding of the chassis) is removed and there is a ground fault" (and if the person is grounded, there can be a fatal shock. Really? Lots of ifs, which many manufacturers ignore.

Shorts or hot wires cause electrical fires. Don't breakers deal with shorts?

Given your fear of electricity, you probably should use a 12 volt system.

I see no reason to continue this tangent off the original question.

"Shorts or hot wires cause electrical fires. Don't breakers deal with shorts?"

Thanks, good point. What is the chance of being grounded and touching the chassis when the chassis is hot anyway. I'll risk it and so does my family.

The chance is extremely high that you are grounded. TBG's pride is hurt. RESPECT ELECTRICITY!
