POWER SOURCES

Conductors from the junction box must terminate in a
double pole, double throw transfer switch (Figure 28).
An alternate method for isolating different power
sources is by using an isolating receptacle (Figure 29
on Page 25). Whichever method you use, you must
be certain that both power sources are NOT connect­
ed at the same time.
