Upgrade service panel, 100 to 200 amps

[Keoke]

Hi folks, When we planned a new home we put the well (1993) in first. From the utility step down transformer to the service panel power company ran a 200 amp line ( 3/0 copper, underground) to a metered service panel. Unfortunately, the service panel installed was a Square D with a 100 amp breaker instead of a 200 amp breaker. Now that we are finally building the house we need to continue from existing panel up to house.
Questions are as follows:

1. Using the same box, can I simply replace 100 amp breaker with a 200 amp breaker?
2. Using a dummy breaker, built like a buss bar, with lugs that will accommodate 3/0 copper cable, continue on to house (underground) from existing well panel? House will have a 200 amp panel with no meter base in garage.
3. If I have to replace with a whole new 200 amp service panel at well what kind of panel (name) would allow me to feed well and also allow for a pass through 200 amps line on to house?

I hope all of this makes sense,
thanks,
keoke

Square D makes a 200 amp pass through panel. It has a main breaker (200)amps and 8 slots for breakers with 4/0 lugs of buss bar to pass the 200 amps on to the next panel.

You will have to replace the existing panel. You can not get 200 amps out of a 100 amp panel.

Square D Homeline series is more competitivly price and has the same type of pass thru panel.

Hockpuck and Texbaylea, could you give me the Square D and Homeline part numbers of these pass through 200 amp boxes.
So it looks like just swapping breakers is out.

thanks a lot fellows,

Do not be scared by the list price. You should be able to get for less than 200 bucks.

Hockeypuck, thanks for the tip. The box you recommended would do the job but did not included the meter socket. So I called 3-D and they gave the part # of the same box with meter socket (sc816d200c). Now I need to find one at a reasonable price; any tips here.

thanks again,

I bought one of these panels at Lowes and it's great for $125 and my power company furnished me the meter can for it with fittings free
