My new breaker panel is installed. It now needs to be inspected, so that the utility company can come out and switch the line from the old service box to the new. That might take a week to do. But the electrician said that the HVAC company can come anytime to install the furnace, and I can use it as long as I don't use the stove or my dryer, which is fine. I am SOOOOOO relieved! I can't even put into words how much stress and anxiety this was causing me. Now to get the furnace installed!
