wired in fuses before behind the circuit breaker. Do those come in different amounts
that are better for outlets that have higher powered draws on them? The guy I bought
the Zeusminer said that it wouldn't run on 110 volts but obviously he had it set up on
regular 3 prong plugs, not the 220 plugs used for washing machines, etc.
I wire my miners up using NEMA 6-20R outlets and NEMA 6-20P plugs, an example receptacle is shown here: http://www.homedepot.com/p/Eaton-Commercial-Grade-20-Amp-Straight-Blade-Single-Receptacle-with-Side-Wiring-Light-Almond-1876LA/203492424
I use 20 Amp double-pole (240V) breakers and usually run about 4 outlets off of each breaker as my miners only pull about 3A-3.5A each, so my total circuit load is at most 14A which is well within the 80% NEC code specifications which allows a continuous 16A load.
I also use NEMA L6-30R receptacles (fed by 30 Amp double-pole breakers) in my garage to power my APC PDU power strips, and I can run about 24 Amps (7 rigs) off of each one of these: http://www.apc.com/shop/us/en/products/Rack-PDU-2G-Switched-ZeroU-30A-200-208V-21-C13-3-C19/P-AP8941
These PDUs work great for the rigs I mount on wire-racks. You can usually find used PDU's online for $50-$100 depending on capacity, features, etc., as they are too expensive to buy new at retail. The main benefit of using a PDU is you can run fewer higher amperage circuits to power many rigs (especially if your circuits will terminate far from the breaker panel.) Some of the better ones also have individual breakers for each receptacle and can remotely monitor power draw as well as switch on/off the outlets via a web-page. This can be a handy feature if you need to remotely reboot or power cycle a rig.
Thanks. Fascinating stuff. I see right now my maximum load will be normal household stuff and 2 older antminers and the zeusminer. I can switch out the 10 amp fuses with 20 amp ones and I am easily on two different fuses between the three miners. It seems ideal to be able to power more with the pdu and a 20 amp outlet.
