ISOLATING DIFFERENT
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.
GROUND FAULT CIRCUIT
INTERRUPTERS
The National Electric Code (NFPA 70, 551-7) requires
that you install ground fault circuit interrupters
(GFCIs) on all external and some internal electrical
receptacles. Contact your manufacturer or dealer for
recommendations.
POWER SUPPLY CORD
The power supply cord must comply with all applica
ble codes, standards and regulations. It must be large
enough to handle the full amperage to which it will be
subjected.
