Replacement new UPS is joining the previous new UPS by putting both 51V AC at 15mA

AND

8-20V DC (usually around 16V) at 16ma

...on the ground pin.

What the fuck, APC? This isn't like you.

Am I mad? None of the UPSes that don't trip GFCIs are putting current on the ground pin. Am I wrong in thinking this is a problem?!

It's like, I'm willing to put up with a little AC on the ground pin. There's a lot of way that shit can happen, a lot of inductive ways that say "this isn't really wrong, it's just not the tightest thing in the world and is losing some efficiency" and that WON'T trip GFCI. So I could kind of frown but tolerate that.

Not be fond! But... AC? Small amounts? Okaaaaaaay I gueeeeeeeeess...

But DC? Fucking DC?!

DC tells me it's not inductive. DC tells me it's past the fucking rectifier. DC tells me there is something broken in your circuit design or your component selection and makes me go, "How long do I have before this trips GFCI and throws my server rack onto battery backup again?"

APCs SHOULD NOT CAUSE POWER FAILURES, EVEN AT THE CIRCUIT LEVEL, EVEN IF GFCI.

(Particularly not if GFCI.)

I have three other APC UPSes that don't do this.

Both of the units I've received trying to replace the one that went bad do...

...just like the one that went bad started doing, when it started tripping GFCI.

What the fuck, team? Seriously, what do I need to do here?
