INSTALLATION
4 2.6.5 ISOLATING DIFFERENT POWER
__________ SOURCES______________________ ________
Connections from the junction box must terminate
in
a double-pole, double-throw transfer switch
(Figure 2.17). An alternate method for isolating dif­
ferent power sources is by using an isolating recep­
tacle (Figure 2.18). Whichever method you use, you
must be certain that both power sources are NOT
connected at the same time.
♦ 2.6.6 POWER SUPPLY CORD
The power supply cord must comply with all applic­
able codes, standards and regulations. It must be
large enough to handle the full amperage to which
it will be subjected.
♦ 2.6.7 GROUND FAULT CIRCUIT INTERRUPTERS
The National Electrical Code (NFPA 70. 551-7)
requires that you install ground fault circuit inter­
rupters (GFCIs) on all external and some internal
electrical
receptacles. Contact your manufacturer
or dealer for recommendations.
