Is installing a buck and boost transformer wired to boost the voltage to mitigate voltage drop over long runs an acceptable method in staying in compliance with the Florida energy code.
Since that code reads "C405.5.3Voltage drop. The conductors for feeders and branch circuits combined shall be sized for a maximum of 5 percent voltage drop total.", you are NOT sizing the conductors to accommodate voltage drop by adding a buck-boost transformer, so no good.
