I did it 31 years ago, and the 120v outlets still work as do the 240v
outlets. The 120v outlets are connected between either L1 or L2 and
N-gnd / CT. The 240 outlets connect between L1 and L2 with the N
connecting to the CT. This arrangement is similar to operating 6v
tubes and 12v tubes from one 12vct filament winding.

Insulation determines current carrying ability?
