content: I ran through IT pretty easily but after getting into webhosting datacenters most daunting task was understanding electricity.  I got the W=V*A and UL allows for 80% of a circuit to be the maximum utilization.  But I tried understanding the difference between DC, AC, and 2 vs 3 phase and just get lost.
