Ungrounded power cord: Will I die?

Electrocution = result
Stupidity = reason.

I was wrong and Elizabeth is right.

The risk of death or injury from floating a ground is so low it is not a practical concern.

I apologize for my previous comment.

Anyone using ungrounded power cords will die eventually. Alas, so will those using grounded ones. That said, as Forrest Gump remarked "Stupid is as Stupid does"; I have known a fair sample of the shallow end of the audiophile pool and none of them have yet succeeded in hifi Hari Kari despite their best efforts. The prize probably went to the guy who built a large outboard capacitor bank, charged it up, unhooked it without discharging it and then tried to hook it up again. He also liked to leave the cage off his EAR 509s despite the presence of potentially lethal voltage. They looked better that way.

That is a universal 100-240 switching supply. Since outlets in many countries don't have a 3rd prong for ground it would have to be designed to not need one.

Herman,

You could be right..... I checked the Net for an owners manual for the unit with no luck. Maybe the OP will chime in and let us know what the manual says.

I did look at the link you provided and noticed the picture of the back of the unit shows the male IEC connector has the safety equipment ground blade contact.

I have no way of knowing if the PS is Listed by a recognized safety testing agency for use in the USA.
(Such as UL)

Just curious about your thoughts,... if the PS uses an IE transformer with an electrostatic shield that is connected to the metal chassis, enclosure, of the PS and the equipment ground contact of the IEC connector. If the ground is floating will that have any effect on the EMI/RFI rejection performance of the PS?

I can say that style of male IEC connector can be purchased without the ground blade contact.

To go back for just a second to the OP's Luxman amp, the manufacture should have supplied with the amp , at least for sales in the USA, a 3 wire plug PC with the IEC grounding type connector. That way the cord would be idiot proof and could be used on IEC fed equipment that require the use of a safety equipment ground.

Just one example, that is how the Arcam Alpha 9 CDP was designed/manufactured. The unit has the universally used male IEC connector with only the hot and neutral blades. No safety equipment ground blade. The unit uses double insulated power wiring.

The cheap OEM power cord the came with the unit is a 3 wire grounding type. The ground wire is not used in this case but if for some reason the cord was just thrown in a box and later found, there would not be safety issue if it was used on a piece of equipment that was intended to be connected to an AC grounded system equipment safety ground.
