Canada Antminer S9 Setup

[Razon]

Quick question.

Canada/North America install

I was told I would need a Transformer since Canadian 220v is between phase, and the transformer will need to be between the sub panel and plug. Can anyone please shed some light on this statement? Ive read other threads but I see people saying to avoid transformers or not needed.

I was planning on setting up 4x Antminers S9's in this fashion.

1) Breaker Panel, 2x 30 Amp breakers
2) Breakers to a sub panel
3) Sub panel to  2x 32A BLUE (2P+E) plugs
4) This will then go to a Tripp Lite PDU (PDUH32HV19)
5) Connected to Bitmain AWP3++ power supply
6) Last to the miner

Thanks in adv!
