I replaced the original 60 amp service in 2008 with a 200, and brought 
this grandfathered 2970 house service up to code, doing all the internal 
work myself. I have a big ups running everything but the lights and 
printers in this room, got rid of the copper telephone because the cable 
was 70 years old, 50 pair paper insulated cable they would not keep 
working for a week at a time, so after 5 months of that I voted with my 
wallet and hooked all that up to the cable system. I must have done 
something right, I have not even blown a ccfl light bulb since and it 
all runs 24/7/365.25.
