Section 6 – Installation

PRIMEPACT 66G and 66LP Recreational Vehicle Generators

•From the junction box, route power supply wires through approved conduit to either (a) double-pole, double-throw transfer switch, or (b) approved isola- tion receptacle. Connecting to a transfer switch or isolation receptacle must prevent vehicle electrical circuits from being connected to two different power supplies at the same time (such as generator and dockside power).

•Conductors must be rated 221° F (105° C) or must be of a larger conductor size.

◆6.7.3 GENERATOR AC CONNECTIONS

Generator AC output leads T1 (red), T2 (white) and T3 (black) come out of the generator as shown in Figure 6.17. Leads T1 (red) and T3 (black) are “hot,” while T2 (white) is the grounded neutral lead. There is also a green lead that connects to ground in the junction box of the recreational vehicle.

◆6.7.4 CONDUIT

Route the connections between the generator and the junction box through approved, flexible conduit. The following general rules apply:

•Cut wiring to the required length and allow extra wire for junction box connections.

•Carefully prepare conduit ends to prevent sharp edges from cutting through wiring insulation.

•Route conduit so it does not interfere with generator movement.

•If you use metallic conduit, vapor seal the end of the conduit where it enters the junction box. Do this because flexible metallic conduit is not vaporproof along its entire length.

Line T1 (red) to T2 (white) is protected against overload by a 30-amp circuit breaker (CB1). Use this line-to-neu- tral connection separately to operate 120-volt, single- phase, 60 Hertz, AC loads requiring up to 3,300 watts of power for PrimePact 66G or 3,100 watts for PrimePact 66LP. Line T3 (black) to T2 (white) also is protected against overload by a 30-amp circuit breaker (CB2). Use this line-to-neutral connection separately to operate similar loads. However, be sure the total unit load does not exceed the maximum rating of the gener- ator. The neutral line (T2, white) on all units is a grounded neutral.

Connections from the junction box must terminate in a double-pole, double-throw transfer switch (Figure 6.18, Page 33). An alternate method for isolating different power sources is by using an isolating receptacle (Figure 6.19, Page 33). Whichever method you use, you must be certain that both power sources are NOT con- nected at the same time.

◆6.7.6 POWER SUPPLY CORD

The power supply cord must comply with all applicable codes, standards and regulations. It must be large enough to handle the full amperage to which it will be subjected. (See page 33 for illustration.)

◆6.7.7 GROUND FAULT CIRCUIT INTERRUPTERS

The National Electrical 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 recommenda- tions.

6.8BATTERY INSTALLATION

◆6.8.1 RECOMMENDED BATTERY

Install a battery that meets the following requirements:

•The battery must be a 12-volt, automotive type storage battery.

•For prevailing ambient temperatures above 32° F (0° C), use a battery rated 70 amp-hours and capable of delivering 400 cold-cranking amperes.

Do NOT connect electrical loads in excess of any circuit breaker rating or you will develop prob- lems with circuit breaker tripping, which causes a loss of AC output. Also, do NOT exceed the gener- ator's rated wattage capacity. Add the watts or amperes of all lighting, appliance, tool and motor loads the generator will operate at one time. This total should be less than the unit's rated wattage/amperage capacity.

32 Generac® Power Systems, Inc.

•For prevailing ambient temperatures below 32° F (0° C), use a battery rated 95 amp-hours and capable of delivering 400 cold-cranking amperes.

NOTE:

If the battery is to be used to power other vehicle accessories, as well as start the generator, you may need a battery with a larger capacity.
