Do most data center providers offer this 400V? The next step up from the 208V/30AMP A/B side was a 208V/30A/3-Phase Power A/B side. I have never dealt with 3 phase before does the MX960 support 3 phase? Not sure if this matters, but the 208V/30A/3-Phase Power is double the cost of 208V/30A/Single Phase Power.
