I’m going to be adding another circuit to my home breaker box for an EV charger. I think I may not be able to do this with the normal NEC calc, but they have a method using existing loads (220.87).
- I need maximum demand over a 1 year period. By the time I get around to doing this I’ll have a years worth of data.
- the highest average kW reached and maintained for a 15 minute interval over a 30 day period.
How can I extract this? It looks like using the graph interface would be cumbersome since the data sample period is greater than 15 min when the sample range is stretched out. It could be done this way, but would take a lot of mouse clicks.
Can it be done with the Query API? Should I limit the size of the query? If so what is a reasonable number of data items, or time period?
