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.

INTERCONNECTION

**** 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.
