Any one got advice on best set up for 240v single phase home mining? Upgrading old wiring to my garage as I’ve got this mining bug and have new and bigger machines coming : S19, Avalon 11’s . I still want to run my L3s & S9’s also.
Have an electrician coming but of the few I’ve spoken to none have ever done mining set ups. Based in the UK so looking for advice, things to think about, best set ups for safety and anything else I should know.
If he’s planning on HODLing and can float the electricity, what’s the difference? The only price that matters is what you sell the crypto at, not what the price is while you mine. If this is just a temporary dip, then stopping mining because we’re currently “in the red” doesn’t make any sense.
Here in the US the general recommendation is to use something like the following:
And then get a PDU of some type that plugs into the outlet to distribute the power. I don’t know what the equivalent is in the UK, but I’d check what plug type is available on PDU’s in the UK and have him put in a series of those.
The general rule of thumb is that you don’t want to ever use more than 80% of the power available on your breaker at a time for normal load. I’d size each breaker to be able to comfortably handle 2-4 units per breaker, and size the wire appropriately.
Really, what your electrician needs to know is the load in watts, the voltage, and the type of plug you want on the end. The rest should all be “normal” for him. The plug on the end will depend on the requirements for your PDU.
Thanks for the reply. My home board is 240 / 100amp and I’m looking to safely maximise what I can. Do I need a PDU if I have enough UK standard 3 pin plug points? Or should I be requesting something different?
I think the advantage of a PDU is that it allows you to run less, but thicker wires, and still fully utilize them. That should save you some cost, and is safer since you’ll have a larger buffer for temporary power draws. Some PDU’s also offer power surge capabilities, which if you’ve got $10k+ equipment, isn’t a bad idea.
There is definitely not a problem with running more, but smaller wires; but realize the thinner the wire the less power can be put on it. Since ASIC miners have large draws, you can quickly exceed your wires if you try to put a lot of units on a standard outlet wire thickness. This should flip a breaker if everything works right, but can potentially cause a fire.
BTW, for calculating the amps you divide the Watts by the volts. For example, the following page says an S19 Pro pulls 3250 watts https://support.bitmain.com/hc/en-us/articles/900000261726-S19-Pro-Specifications . At 240 volts that’s 14 amps, which means you’d need a 20amp breaker to get the 80% and at least 12AWG wire to ONLY run that one unit on that breaker without anything else (To be clear, its technically ~17amps, but at least here I don’t know of 17 amp breakers). It doesn’t matter how many plugs are on that wire. You can’t exceed the amperage without tripping a breaker or causing a fire.
Really, your electrician can do these calculations if you look-up what the power draw is on everything you use, or may want to buy soon. (Please validate that the link I gave is the same unit you have before going off that number though).
For your reference though, the following page has a chart for the approximate wattage per AWG wire thickness needed which will give you an idea:
Two S19’s are going to exceed the amp draw on the “normal” wiring put in a house which is typically 14AWG or 12AWG. (At least here in the US, but I imagine the UK is similar or smaller wire since you typically run 240V power instead of the standard 110V here, which reduces the amp draw)
Awesome. Listen to this guy over me :-). I’m just a home DIYer who has watched a lot of Youtube videos on electrical ;-). I don’t think the concepts I’ve said are wrong, but he’ll have a much better idea.
