upgrading to 300 amp service
I have a 200 amp service now, but am putting in a geothermal heat system, then will be adding on to the house and eventually will be putting in a new kitchen. As it is now, I might be able to skate by with the geo thermal, but am sure I will have to go bigger when we add on.
My question is, what needs to be done to increase the service? And, what might it cost? Do I just need a new panel, or will I have to bring in more power on another line from the street? Our lines are buried, so that will be expensive.
I'd like to have some idea before speaking to electricians about it. Thanks.
