SecTIOn 3 | Installation
mounting location
The unit can be installed near the power cord entry of the rV or near the location
of the generator output
on the line side of the main distribution panel, or it can be
installed on the load side of the panel between the main panel and a sub panel, al-
lowing switching for either the entire electrical load or only designated circuits. Typical
locations include under counter cabinets, below closet compartments, inside the bed
pedestal or cabinets, overhead cabinets, under-floor storage compartments accessed
from the vehicle exterior, etc. The chosen location must be accessible after installation is
complete to facilitate future servicing.
cable entry and exitS
A number of ¾” and 1” knockouts have been provided on all the sides (7, fig 2) for ease
of routing the input and output cables. Choose a knockout that will facilitate installa-
tion and service within the selected mounting area. Use 3/4” or 1” cable clamps as neces-
sary to clamp the cables entering and exiting the box.
mounting
Mount the unit with screws through holes in the bottom of the unit. The unit should be
screwed to a solid surface firmly enough to hold its weight during vehicle operation.
making electrical connectionS
1. Attach an 8 gauge earth ground wire to the transfer switch chassis ground lug (6, fig 1). 4 studs
with serrated lock washers and nuts have been provided on the inner bottom of the case to make
grounding connections from the inner side . These are marked:
2. The color code for 120 VAC wiring is as follows:
• The "Grounding" wire is bare or green.
• The "Neutral" wire is white.
• The "Line" wire is black.
3. A ¾” cable clamp has been provided (4, fig. 1). Additional ¾” and 1” knockouts have been pro-
vided for convenience. Please ensure that a cable clamp is used for the cable entries.
4. for making firm connections to the terminals (T1 to T6, fig 2) of the Transfer relay (r1, fig 2),
please crimp appropriate size of insulated ring / spade lugs on the ends of the conductors of the
cables.
5. Connect the grounding conductors (green / bare wire) of the cables to the spare grounding studs
marked ( )
6. Two or more conductors can be spliced together using the appropriate size of twist-on type of
cone shaped, plastic insulated wire nut connector - also called "Marrette" (See fig. 3). The connec-
tor twists over the wires to make a tight connection around the wires. A square-cut spring inside
provides tension on the wires to hold them secure. As you tighten the wire connector, the spring
draws tighter around the wires.
Fig.3. Twist-on type of wire nut connector.
To splice the wire leads using the wire nut connector, hold the bare ends of
the wires parallel to each other so that the wire tips are even, then secure
with the wire nut. Use the proper size nut. Manually tighten nuts as tightly
as possible. Verify that all connections are tightened.
