INSTALLATION

Series 185

 

 

Installation of the ASCO Series 185 automatic transfer switch (ATS) must be performed by a licensed electrician. It must be installed according to the National Electrical Code (NEC) and all local electrical code requirements. Remove the enclosure cover and inspect the ATS for shipping damage. If damage is evident do not install the ATS.

1 --- Mounting

Refer to the enclosure outline drawing. Mount the ATS according to details and instructions shown on this diagram. Mount the ATS vertically to a rigid supporting structure. Level all mounting points by using flat washers behind the holes to avoid distortion of the enclosure.

NOTICE

MALFUNCTION or SHORTENED LIFE Protect the automatic transfer switch from construction grit and metal chips to prevent malfunction or shortened life of the ATS.

Transfer switches rated 260 and 400 amperes are mounted on an insulator backing piece (installed behind the transfer switch). If the transfer switch is removed from the enclosure and then reinstalled, this insulator must be placed behind the transfer switch. See Figure 1.

FLASH HAZARD – DAMAGE

Be sure that the insulator piece is installed behind the 260 and 400 ampere transfer switches.

2 --- Electrical Power Connections

Refer to the wiring diagram. The ATS must be protected by suitably sized circuit breakers feeding the utility and generator source terminals. The rating of the circuit breakers must be based on the requirements of the National Electrical Code for its nameplate ampere and short circuit withstand ratings.

ELECTROCUTION HAZARD Turn off utility power and turn off the generator to prevent electrocution when wiring the transfer switch.

Cable Spacers for 150, 200, and 230 A

Three cable spacers are included with 150, 200, and 230 ampere transfer switches. Run the copper power cables through the cable spacers as shown in Figure 2. Position the cable spacers approximately 1½ inches from the terminal lugs.

NOTICE

CABLE LOOSENING DUE TO SHORT CIRCUIT Install three cable spacers 1 1/2 inches from the power terminals to prevent the cables from loosening during a short–circuit condition on 150, 200, and 230 ampere transfer switches.
