Because of the many different types of service,
feeder, and distribution equipment, no specific wiring
instructions can be provided. It is, however, recom-
mended that copper wire be used. In all cases it is
essential that while the load is connected to the gen-
erator, there can be absolutely no feedback from the
generator to the power line or the power line to the
generator. When properly installed, the normal ATS
control and safety systems will eliminate all paths for
feedback. Check with your local electrical inspector
on applicable local, state and federal codes.
******************
***** WARNING *****
******************
A service disconnect must be installed in front of the
ATS panel as the ATS is not service enterance rated.
This will alow you to test the generator under load.
Should you ever have to work on the switch, you will
be able to disconnect the power and work on the
switch cold without having the power company pull
your meter.
To wire the automatic transfer switch into the exist-
ing wiring, first determine which circuits will be on
the emergency load circuit. If the entire load is to
be transferred, the transfer switch can be wired in
directly after the watt-hour meter and the service
enterance, providing the service enterance ampere
rating is within the transfer switch’s rated capability.
If only specific circuits are to be powered under
emergency power failure conditions, and additional
distribution panel designated “emergency distribution
panel” must be installed.
All selected emergency circuits are removed from
main distribution panels and reinstalled in the emer-
gency distribution panel. Suggested circuits: freez-
er, refrigerator, furnace, emergency lights, sump
pump, emergency outlet circuits, etc. Total running
load must not exceed generator rating.

**** CAUTION ****
Never run the AC and DC wiring in the same con-
duit.
ASCO 165 UL SWITCH
Your DC connection points in the ASCO 65 UL ATS
are on the terminal block in the upper right hand
corner of the ATS panel. The terminal block (TB7)
is numbered through 9. These terminals will
accept # 22 - # 4 AWG stranded wire. It is recom-
mended that you use # 6 AWG for distances up to
200 feet.
You need to run four (4) wires from the engine gen-
erator set to the transfer switch, see table below.
WIRE # PURPOSE RECOMMENDED
COLOR
# 5 Battery Positive Black
# 1 Battery Negative White
# 24 Fuel Solenoid Red
# 22 Start Orange
You can use any color you want, these color codes
are just a recommendation. The wires terminate on
TB7 as follows:
WIRE # COLOR TB7 TERMINAL
# 5 Black # 3
# 1 White # 2
# 24 Red # 4
# 22 Orange # 7
Jumpers will need to be installed as follows:
WIRE # COLOR TB7 TERMINALS
# 5 Black # 3 & # 5
# 5 Black # 5 & # 8
