"For Rod, second part...
When I see really large electric services... my first reaction my be "what a waste", but when I stop and catch my breath and take the time to ask why... something more useful is generally discovered.
"Rod, I did see earlier that you had calculated the loads. The key is even though a consumer device may not have the accuracy... you can still use it to find the "phantom loads". You need to use that spread sheet of…"
I have some of the CT's that you referenced in the openenergymonitor system. They are at "best" 3% devices... the openenergysystem is likely to have system error/uncertainty in/around 10%. The utility meters…"
"1200A service... really? or did you mean 200A. That size service would likely result in its own large transformer (probably ground mounted)... and likely three phase to home.
The electrician likely did the audio/video system as well as a…"
"yes, I'd think even for a very large house / residence that you'd want to look carefully at the loads and decide which of the motors you want to put on timers and upgrade to more efficient motors ASAP.
Besides well pump, if the…"
"It's not just the CT's that you need to worry about. The CT will pick up the current and provide a voltage across a "load" resistor that can be measured. The system accuracy of the external measurement is dependent…"
"I have TEDS, they ARE NOT REVENUE grade. The 1000's and 5000's have serious problems in which they can under report or over report (randomly)... they are really only useful for getting a rough feel. And I've been…"
"In the case of the threads original author... that would mean that the readings the utility would be taking and basing their monthly charges would be LOWER not higher than the authors digital data logger. E.g. the worst case if the meter was…"
"If you wish to be successful in arguing with the utility, make sure that you've had your monitoring equipment tested and have a valid certificate of calibration that includes the accuracy. It needs to be traceable back to NIST through a known…"
"Dishwashers, washing machines and now dryer standards have also been subject to test procedures that might not match reality in the field... but are convenient for the manufacturers.
Dryers specifically have the standard test loads - for the drying…"
"Bob provided a good answer below. Since this is a building of historic value I'd also check with universities in the state to see if they have preservation specialists. Step back and work the problems together and while the cost…"
"You are going to want to include pest control (ant's, termites) consultant in your planning meetings. Some of the easy solutions (spray in foam), may offer a great home and food source for the pests."
