Re: Why choose 120 volts?

1) Equipment used to not be dual voltage

2) For smaller scale, 120V UPS and distribution equipment is usually
cheaper

3) 120V embedded itself into operations as a result.

4) We're all lazy and hate change.

I have a pure curiosity question for the NANOG crowd here. If you run
your facility/datacenter/cage/rack on 120 volts, why?

I've been running my facility at 208 for years because I can get away
with lower amperage circuits. I'm curious about the reasons for using
high-amp 120 volt circuits to drive racks of equipment instead of
low-amp 208 or 240 volt circuits.
