I'm in the planning stages of finishing a room in my basement. The
main panel for the house is 200A and is located in the basement. What
I would like to do is add a second 200A panel just for the basement.
The reason why I want to do a separate panel for the bsement (not a
sub panel) is that at some point in the future we may want to move the
washing machine and clothes dryer into the basement, possibly put a
kitchen, and maybe a hottub. The house is 7 years old, and all
electric w/ a heatpump. Initially the basement will be used to host
LAN parties (parties where everyone brings their computers and has fun
gaming against each other) for up to 30 people (30 computers and
monitors).

Am I right that a sub-panel off the 200A main panel would not be the
way to go?

Is it even possible to do something like this:
Utility --->Meter-------------
| |
| |
200A 200A


Instead of this:
Utility --->Meter ------200A ----- 100A


To accomplish that would I have to have 2 meters? (against zoning to
have 2 meters on a single fam residence where I live.)
Utility --->Meter--------Meter
| |
| |
200A 200A


Or would I have to do this?
Utility --->Meter ------400A ----- 200A

Of course whatever I do will be done by a licensed electrician.
Thanks in advance for any advice.

If you're breaker panel is already in the basement, then all you need to do
is add the circuits. You're not talking about that much additional current
needs. And since your "moving" the washer and dryer, there's no more draw
than you already have on those particular items.

Why? You're only talking [below] about another 30 or 40 amps of load (the
washer and dryer don't count -- that's not new load, just relocated load).
What do you need with a second 200A panel?

So? That doesn't preclude installing a subpanel.

A subpanel is definitely the easiest and lowest-cost method of expanding the
number of available circuits. I don't understand your reluctance to do this.
Why would you want to add another main panel?

And of course you may not even need to do that, depending on the space
available in your current panel.

With respect to whether you need a subpanel or a main panel, no, it doesn't
matter. The electrons can't tell what kind of panel they flow through.

Have you verified those numbers with a clamp-on ammeter, or are you just
extrapolating from the power supply rating?

The last one In retrospect dumping the salt OUT OF the bags into wheel
barrow ( clean) spreading around the pool with shovel might of been a better
idea, to bad I didn't think of that.
