If you have the following breakers;

50 electric range
40 central a/c
30 water heater
30 dryer
60 subpanel of 120V circuits
------
210 total

Then what is the appropriate service?

Assuming it's an overhead service, the procedure is to remove the existing
service entrance cable, meter pan, panel, and grounding system and replace
all with 200 amp rated equipment. In the Northeast this typically runs from
$1500 to $2500

Anyone done this? What was the approximate procedure and cost? Thanks.



The size of the service is found by taking the finished square feet of
the dwelling and multiplying by three. That gives you the volt-amperes
of lighting and convenience receptacle outlets that are not required by
another section of the code. You then add 2400 volt-amperes for each
kitchen counter circuit, two required; a laundry circuit; each bathroom
receptacle circuit, one required; the volt-ampere rating of each
appliance fastened in place, the larger of the heating and air
conditioning loads and so forth. The resultant volt amperes sum is
divided by your service voltage to obtain the size of your service in
amperes. There are on line tutorials that will walk you through that
process. Breakers are sized to protect the conductors of the circuit
through which they are supplied not by the loads those circuits actually
carry. The sum of the breaker ratings tells you nothing about the size
of your service.
