Select the breaker(s) used in your project. If you have more than 10 different ratings, just run the calculator with the first set of breakers, record the results, then repeat with the next set of breakers. Continue until all breakers have been accounted for, then just sum the results.
The calculator will determine the watts loss for each breaker at the full load and compare the watts loss for an equivalently sized fused switch at the same load. The calculator will then compute greenhouse gas production differences and energy cost differences.
Note 1: Laboratory testing was only done at full load. Heat losses at less than full load are scaled by a factor proportional to
the square of the current reduction (i.e. 90% load = 81% loss, 80% load = 64% loss, etc.)
