anyone run 240V for servers?

[Phil Marsh]

Hi,
I'm now trying to run my servers in my rack from a newly-installed 240V
circuit. Code required a GFCI 240 dual breaker since this is in my basement.
I have a whole-house battery backup so I don't need a UPS, just a surge
protector. I do have a whole-house surge protector but not sure if this is
enough?
I would like to get NEMA 6-20 or 6-15 outlet surge protectors. I tried
these:
https://www.amazon.com/dp/B07SS77B9Q?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
but it appears that they were not tested by the manufacturer on GFCI 240V
NEMA 6-20 circuits and therefore trip the GFCI protection randomly. Any
imbalance between the two hot wires' currents will trip the GFCI protection
and I suspect these surge suppressors are doing that because I don't see
this problem when my equipment is plugged directly into the 6-20, 240V
outlets.
Do you think the whole-house surge protector is good enough?
Does anyone here run 240V in their personal servers and if so, how did you
handle this? thanks
Thanks,
Phil
