Isn't 208V usually provided as a connection across two phases of a 3
phase circuit?  In that case, you get 120V by going between one phase
and neutral (no transformer required).

You need a NEMA 14 (4 wire) connector to get two phases, neutral, and
ground (provides 1 208V circuit and/or 2 120V circuits) or a NEMA L21
(5 wire) connector to get all three phases, neutral, and ground
(provides 3 208V circuits and/or 3 120V circuits).
