How do I check whether power delivery to my pole and thence underground to my meter is capable of delivering 200A service? If not, what can I expect to spend for this and the upgrade to my panel?
Most commonly services are limited to 100A. Highly unlikely that existing cabling would support an increase, however sufficient size of conductor could be found through a local electrical contractor. Here in Edmonton average cost of a service upgrade to 200A will start at around $3000 and go up from there depending on conditions. We've heard of customers being quoted by other contractors at around $8k.
Most local utilities will supply 200 amp feeder if the service is underground and belongs to them. As mentioned, you need to contact the utility to confirm if it is available. Some utilities will charge for the upgrade if possible, some will not.
If you own the underground wire, then it is possible that all that cost will be on you, and of course distance from the pole to your home is the main variable as this may involve digging up the yard, concrete, sidewalk, etc.
Next step would be contact three licensed electrical contractors to get estimates for your area.
