PRIMEPACT 50 Recreational Vehicle Generator

◆2.7.2 WIRING

•Wiring should be of stranded copper to reduce the chance that vibration may cause breakage.

•Wire gauge size should be large enough to handle at least 115 percent of the installed generator's rated maximum current.

•If neutral conductors are used, they must be the same size as other leg wires.

•Route power supply conductors from generator AC output leads T1 (red), T2 (white), T3 (black) and the green ground wire through approved flexible conduit to the electrical junction box on the com- partment wall.

If flexible metal conduit is used between the genera- tor and the compartment junction box, the conduit end that terminates the compartment junction box must be vapor-sealed. Flexible metal conduit is NOT vapor tight along its entire length.

•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.

◆2.7.3 GENERATOR AC CONNECTIONS

Generator AC output leads T1 (red), T2 (white) and T3 (black) come out of the generator as shown in Figure 2.17. 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.

Figure 2.17 – Generator AC Output Leads

Line T1 (red) to T2 (white) is protected against over- load by a 30-amp circuit breaker (CB1). Use this line- to-neutral connection separately to operate 120-volt, single-phase, 60 Hertz, AC loads requiring up to 3,600 watts (3.6 kW) of power. Line T3 (black) to T2 (white) also is protected against overload by a 20-amp circuit breaker (CB2). Use this line-to-neutral connection sep- arately to operate similar loads. However, be sure the total unit load does not exceed the maximum rating of the generator. The neutral line (T2, white) on all units is a grounded neutral.

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 gen- erator'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.

◆2.7.4 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 genera- tor 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 vapor- proof along its entire length.

◆2.7.5 ISOLATING DIFFERENT POWER SOURCES

Connections from the junction box must terminate in

adouble-pole, double-throw transfer switch (Figure 2.18, Page 33). An alternate method for isolating dif- ferent power sources is by using an isolating recepta- cle (Figure 2.19, Page 33). Whichever method you use, you must be certain that both power sources are NOT connected at the same time.
