It is my understanding that I can run one 1400w miner per 240v circuit at 5.83A. If my breaker is 15A I can fit 2 S9's on one circuit and be at 77.7% load, correct?
* Should I up this to 20A just in case of spikes?
* Should I stick to individual circuits?
* What if I up the breaker to 30A?
* Will multiple miners on a circuit impact my power consumption used as opposed to individual circuits?
* How does a PDU work/compare in this situation? Can I run more than 2 miners off of one 240v circuit in this case?
* Should I use some type of surge protector anyways? (Using APW3++ PSU)
I have an electrician coming tomorrow and would like to be able to know exactly what I need.
At the moment my panel has 3 breaker spots remaining. I am intending on telling the electrician to install a sub panel directly below. Luckily where I'm planning to have my miners is a short run from the main panel. I plan on telling him to run 4 -240v circuits w/20A breakers to my mining location. I will then run each miner on its own circuit for now. However I plan on ordering 4 more miners a few months later once evaluating/researching further. I would like to add these new miners without having an electrician come by again in the future.
I understand some of these may be simple questions but I haven't found clear answers and have seen both set ups used. Just would like some clarity before miners arrive. Any additional info is appreciated,
Thanks
Edit: In Ontario, Canada by the way.
