I need to plug my 3 pin power plug, into a 2 pin converter. It only works if I plug it in upside down (so to bottom prong is sticking out while the top two are plugged in). Is this safe?
If upside down, neutral and hot will be swapped.....if there is a failure, the case of whatever is plugged in will be hot. Dropping the ground, although not a great practice, generally causes no problems.......but flipping plug polarity is asking for trouble. Often the plug has a wide blade and a skinny blade to prevent this.
True for most consumer devices. However, the WA3 ties them together....No telling how many other amp manufacturers do. At a minimum, check before flipping.
Hmm. So they didn't even bother trying for UL, huh?
Unknown, mine has no sticker, so I doubt it. I discovered this while chasing down a ground loop in my system. My flat screen TV has earth ground tied to chassis only and neutral tied to circuit ground. The Woo has circuit ground tied to earth ground. Connecting the two resulted in pretty bad hum.
Say what? Neutral is connected to circuit ground? Neutral shouldn't be connected to anything but the primary side of the power transformer.
