Dedicated power

I'm looking to run a dedicated 30a and dedicated 20a line to my system directly from the fuse box. 
I currently have some florescent lights and some other junk on the line so I'm hoping it will be an improvement. Things sounds like they are straining somewhat when you crank things up. The amp will go on the 30a line and the digital stuff on the 20a. 
Anyone done this and saw improvements?

900W / 120Vac = 7.5 amps

So how does the designer of the sub spec, "Output Power 3000 Watt"?

Same way Sears used to claim they had 6 hp shop vacs. Theoretical number a fraction of a second before the device went up in flames. Shameless marketing.

Where all the services are underground, there are vaults with transformers.

In my current location we have small above ground transformers every few houses and a large vault with a larger transformer. It also got rather wet and shorted in our 101 inch rain in 2017

I understand underground electric service but I have never heard of the transformers themselfs actually being installed underground or what some would call "below grade" and that would be for the reason you mention that it would be subject to the results and effect of flooding.

It would seem like the transformers used would have to be somewhat sealed being that they are filled with oil.
More to discover
