Hi Guys,

Hoping someone could help with an issues I am having.

I have a three phase 200amp service in my shop and I am getting electrical interruptions or surges when I power my miners on. Here is the setup:

I have 5 2 pole 40amp (220) breakers in which I was aiming to power two  http://www.parallelminer.com/product/delta-2400watt-power-supply-platinum-94-200-240v-dps-2400ab/ and four Avalon 741 on each.

My total current set up is 12 Avalon 741s and two Antminer L3s.

The issue I am having is when everything is powered on or even 3/4 are powered on I get lights flickering, computer UPS buzzing, outside lights buzzing.

I have had my city check the neutral line, as to me it seems like everything is drawing more power because the miners are or the neutral isn't letting power back. I am at a loss as they said everything is fine. Any opinions are welcomed?

Thanks in advance.
