Is it a hazard to plug a surge protector into an ungrounded GFI outlet?

post #1 of 2
Thread Starter 
Don't worry, this isn't for my theater room (but I'm posting here because its likely to be THE place where informed people will be able to give me guidance)!

I have an old home that's been ultra-renovated and upgraded. Nearly all plug outlets are grounded, but as luck would have it, the outlet immediately behind my bed is not. I've got an adjustable bed with a 3-prong plug, and felt very nervous about plugging it into an ungrounded outlet, so I had the outlet switched to a GFI (or, as some say, GFCI) outlet, and all's been good. I'd love to use one of my old surge protectors as a power bar in that outlet, but I wonder if that could be risky somehow. Would the voltage mojo in a surge protector go haywire in an ungrounded GFI outlet? Is there any kind of danger, aside from the surge protector not really working as a surge protector?

It will be safe for humans (GFCI's are designed for human safety), but the surge protection may/will be limited. Some of the surge protection functions use the safety ground. Sometimes power conditioners and 3 wire GFCI don't mix. The power conditioner uses the safety ground wire to dump the noise current, then the GFCI notices that the hot and neutral currents are not equal and trips.
