I ran across this site accidentally today and found someone who had many of the same issues I need help with. Most of my questions were answered reading the forum however I have one more, using the following information I am hoping someone can help.
The existing house is apx. 2300 sq ft w/a 200 amp service. I am adding an additional 1800 which will include the following: 1 bed room, 1 full bath w/a Jacuzzi and a steam shower, a gym and a 900 sq/ft garage/workshop which will have several power tools including compressor Additionally there will be a 3 ton HVAC (heat and air are electric)
In the existing house has a 200 amp breaker panel box wired back to back to the meter with only 70% of the slots used. The meter is now inside and needs to be outside. Additionally, I was going to put a 125 amp panel box in the addition but I got a like new 200 amp panel with all the breakers for $25 so I am using it in the addition.
I have pre wired ready to attach to the locations with 3 - 3/0 & 1 - 2/0 copper in conduit (from the existing meter to the new meter location) & (from the new meter location to the existing panel and to the new panel)
I had used a square D combo box with a 200 amp breaker and the meter all in one. However due to its construction I cannot put duplex lugs on the down side of the box. Additionally with the 2 breaker panels rated at 200 amps @ I now need a 400 amp breaker.
I need help finding either a combo box with a 400 amp breaker, or suggestions on how to re fit the exterior panels and where to locate them (for a good price, smile)
Thanks, MJ
