Electrical Circuit and Wiring Information B-7
Figure B-6 shows a three-phase 208-volts AC, Y-, or ∆-source circuit connection,
which is a phase-to-neutral source connection. Note that the X input on the system can
be connected from L1, L2, or L3. This application requires a single-pole circuit breaker.
