It will be cheaper if you do it by yourself, it’s really easy and if you have some electrical questions, just ask.

Bullshit. You are not talking about adding a few low power outlets to a room or opening up and working on a moderately low power (compared to commercial/industrial capacity) household breaker panel.

The knowledge required to properly and above all - SAFELY - do the wiring for 10's to several 100's of kW of power is vastly different. Even more to the point usually mining farms are a business that should carry insurance - that is not going to happen if it has not been wired by licensed professionals.

You are not good as electrician, safety it’s first place for electrician all time and no big difference of 10kW and 100kW, license is not for 10kW or 100kW of power. You can receive license for system up to 1kV(most popular) or for up to 10kV+, but it’s not a kW!

Dude, you should take a look at folks previous posts before making a comment like that.
I have been designing and building industrial power systems since the mid 1970's. I've done power for industrial lasers that pull over 1MW from what amounts to their own mini-substation.

Yes licenses are geared to working voltage but the point that really matters here is what the source can supply to a short-circuit. Just look up 'arc flash hazard' to see the huge difference between DIY wiring in a house where the SCCR *may* be as high as 10kA vs what can can happen when the building service can supply that amount as a normal load. A good example of PPE that is required when working on the high energy areas of building power can be found here. For the vidiots out there here is some very graphic video of what arc flash can do.

Point is wiring power for a large farm is NOT something that is DIY unless you know damn well what you are doing and have experience dealing with that kind of power.

Haha, if you can't read a message, why are you writing? Just look how it's done and what's kind of plug extender is used. He can just change plug extenders for a few good one and save a lot of money for future(Even just based on cable cross-sections). You don't need any license to buy plug extender, if you don't know which type you need, you can ask seller in shop and check by searchs or ask electrician. You can do it by yourself just with parameters for your equipment.
All work can be done by qualified electrician(INPUT CIRCUIT BREAKERS, JUNCTION BOX, CABLE ROUTING) and it should be done in buildings by qualified electrician, but according to you, the connection of new servers in the data center is done by an electrician, and not by administrative personnel.
