Still don't understand how this will "supply" any "watts to [12V] mining equipment [OP]" though...

That's the job of the power supplies.

So - basically - you're saying "this PDU" will not be "supplying" any "Watts to mining equipment...?

And even if you assume any role for PSU's than certainly those 100KW will not reach cet "mining equipment"...?

I believe most people who read this thread will understand the context that the 100KW is the "at-the-wall" power consumption of the equipment, before any losses due to PSU inefficiencies or wiring losses downstream of the PDU.

Possibly, but some (like the OP, maybe) won't:

I am not that good when it comes to electrical matters.  

First person to tell me (correctly) how many watts this PDU can supply to mining equipment, wins the bounty:

Each of the 3 distribution panels (208/120 breaker panels) would have a 225 amp main breaker, not one single 225A breaker on the 208V output of the transformer.

Transformers are sized to permit 100% of their rating therefore 278 Amps (100080 watts) of 208V is avaliable for the 3 distruibution panels to share depending on connected load at each panel. In theroy it would be possible to load up the distribution panels (even following the 80% rule) to exceed the 278A output of the transformer but doing so would cause the main transformer breaker to trip on overload.
Best to have a qualified electrician or electrical eng review your plans.

Always a good idea to get a review by an expert. Some transformers can be overloaded depending on their insulation class and ambient temperature.
