****I did create a new username because the last one was not the best and I could not change it. This is not my first post.****

As tax return season is coming quickly (for most people with typical jobs) my wife and I have decide to pull the trigger and run electricity to the shed in the backyard and start scaling our mining operation up.

We currently have a free 50amp breaker from a hot tub that was removed before purchasing the home. The house is set up for 200amps total base on the main switch I see on the Electrical Panel in the garage.

We are in the process of getting bids to run a sub panel to the shed for the electric. But before we have electricians come out and ask us questions that may be over our heads (like how many 220v and 110v would we need etc.) I figured I would ask for a rough idea on here. You advise will be just that.... advise for me to continue to brain storm on and have the final plan up hopefully by Feb. 1.

I would like to have 3 220v outlets that I would have 3 PDU plugged into for the miners so that if a given.

How many 110v outlets would be needed for fan (3-4 box fans for movement and 3 450 cfm vortex fans for heat exhaust--cool air will be from passive cooling because of the negative pressure.

Questions I wanna know before I ask someone in person:
1. If my panel is only 200amp, can we reduce any amps for the bedrooms to give more Amps for the shed?
2. Can we add a brand new 200amp box just dedicated for the shed but would be billed on the same electric bill monthly? (might be a eclectic company question)
3. Can I put the electrical wiring and the Ethernet wiring in the same trench or run them on the fence line to the shed to save from not digging? (Shed is approx. 170ft away from panel)

any possible ideas, or other things to think about please let me know. I don't want to spend $1000-$2000 just installing electric when there might be better ways

#1) It's 240V service, not 220V service. (That 20V difference is 600W on a 30A circuit).
#2) You need a 10/3 (10 awg 3 conductor) wire for each 30A circuit. This will cost you like $1/foot
#3) You'll need a conduit large enough to house 3 conductors. Another $1/foot.
#4) You'll need 3x 2 pole 30A breakers ($20ea)
#5) You'll need 3x L6-30R at the end of your conduit, each connected to a single conductor set. ($20ea for the housing and the outlet)
#6) From there you'll just need to find a PDU with a L6-30P that's capable of connecting to the L6-30R. There are a lot of these around with a variety of features from monitoring to switching. (Being able to remotely reboot your miners is a nice thing, but it'll cost you)

I would estimate materials cost for your build at: $800... From there it just depends on what you can get an electrician to do it for. Maybe you can run / bury the conduit with the cables in it (that'd be the costliest part of this, the rest of it could be done in an hour or 2). With these parts you'll end up with 90A of service with 72A usable (17.2kW) over 3x 30A (24A usable) lines.

From an installation perspective... You'll need to install the 2 pole breaker, insert 1 red conductor to one pole, insert 1 black conductor to the second pole, and green or uninsulated conductor to the grounding bar (WHICH IS NOT THE SAME AS A NEUTRAL -- DON'T KILL YOURSELF THINKING THE GROUND AND NEUTRAL ARE THE SAME). Run the conductor through the buried conduit to your shed. connect the conduit to 3 junction boxes each housing it's own L6-30R. Connect black and red to their respective hots, and green or uninsulated conductor to the ground on the receptacle. Install your PDUs. Start mining, then switch your concern over to cooling with summer approaching

Here's my PDU: https://www.amazon.com/gp/product/B0013HY9E2/ref=ox_sc_act_title_5?smid=ASF0S1GFIHF5V&psc=1 -- But it does only have 2x 15A breakers which means you can only use only 12A on each breaker bank. There is a monitored version (cheaper) which has 2x 20A breakers, but doesn't give you remote reboot functionality.

If your house is anything like mine, you won't have to worry about voltage drop. I'm running 245V at my outlets. Down at my barn (maybe 150ft) there is zero voltage drop.

Thank you for your post.

My shed has been wired (yes 10/3 with 2x30amp L6-30P outlets for the Tripplite PDUs that are in there right now. I will add 1 more outlet when I need it. The PDUs are not switched but just a basic version to get me up and running on my rigs down there.

I currently have 3 rigs running right now and the shed is staying around 65degree (F). Cards are running between 46C-65C depending on which card and where it is in the shed.

I have order 1 more exhaust fan rated for Approx. 500cfm.

I messed up and said I had 2 400+CFM and I really have 1x190cfm and 1x450cfm vortex fans. So 1 more additional exhaust fan will be good for the shed. I plan on cutting a smaller intake hole for the 190CFM vortex and having that on a fan controller to control how much fresh airs gets in. (my idea is to help maintain humidity this way also. not an issue not but thinking for the future) I been and seen other peoples ventures (grow rooms) that needed lots of exhaust and this is what they recommended I do.

Finally, I am order the last 2 mother boards today (hopefully) and will put those rigs together this week and throw them in there.

Once I get all rigs and the new vortex fan hung up, a final video will be made. I will include some parts of the other videos such as the running of the electric and Ethernet cords to the shed from previous photos/videos I have taken.

I am approx. 85% completed with the shed in my opinion though. Thank you to everyone who has commented and been patient as I get the video ready. Once you see the completed video, you will be happy.

My house is super quiet now that I moved those rigs to the shed to test the temps and stuff haha.
