OPM-155/A

A.C. CONNECTIONS

NOTICE: CLASS 1 WIRING METHODS ARE TO BE USED 

FOR ALL FIELD WIRING CONNECTIONS TO TERMINALS 

OF A CLASS 2 CIRCUIT

All wiring must be completed in accordance with the 

National Electric Code as well as any state and local codes.

You must pay particular attention to wire size requirement 

for the amperage of service you are dealing with. The table 

below provides you guidance on wire sizing based on both 

wire type and amperage. 

Wire amperages have been 

derated for 40° C ambient temperatures operation.

WARNING

Make sure the generator is disconnected from the 

battery to prevent accidental starting. 

A. NEUTRAL LUGS:

  These lugs are isolated from ground and provided for you 

  to connect your neutral wire from the transfer switch to 

  the generator.

B. GENERATOR CIRCUIT BREAKER:

WARNING: PERSONAL INJURY/DEATH

A mainline circuit breaker has been provided inside 

the generator housing. During all wiring installations, 

make sure the breaker is in the OFF position and the 

generator operating switch is in the OFF position.

 

  Your generator is equipped with an electronic circuit 

  breaker. These premium circuit breakers are adjustable 

  allowing you to fine tune them for your applications. 

  WINCO uses an adjustable breaker, which allows us to 

  use the same breakers in reconnectable units. These 

  adjustment should only be made by a competent 

  technician to prevent equipment damage, injury or 

  death. The following features are adjustable:

Long-Time Protection: 

  The dial that controls the long-time protection is labeled 

 Ir. The dial correlates with the amperage setting of the 

  long-trip. All the wires should be sized equal to or greater 

  than this dial position. The breaker will not trip at 105% of 

  the dial position current and will trip within two hours of 

 

120% of the dial position.  

Short Time Protection: 

  The dial that controls the short-time protection is labeled 

  Isd (x In). This setting controls the inrush current the 

A

B

C

D

E

  circuit breaker will allow. The number on the dial is the 

  current allowable based upon the long-time (Ir) setting 

  of the breakers. For example, if the Ir of the breaker is set 

  at 200 and the Isd is set at 1.5 the short term breaker 

  setting is 250 amps. 

Instantaneous Protection: 

  The dial that controls the instantaneous protection is 

  labeled Ii (x In). The breaker will trip immediately upon 

  reaching this current level. The dial is set as a multiple of 

  the Long-time (Ir) setting. 

The circuit breaker has three LED lights on it.

Ready LED (green)

  Blinks slowly when the electronic trip unit is ready to 

  provide protection. 

Overload Pre-Alarm LED (orange)

  Shows a steady light when the load exceeds 90% of the Ir 

 setting.

Overload Alarm LED (red)

  Shows a steady light when the load exceeds 105% of the 

 Ir setting.

C. GROUND LUG:

  These ground lugs are bonded to ground and are 

  provided for you to connect your ground wire from the 

  transfer switch to. The lugs will accommodate #6 AWG to 

  300 MCM and should be torqued to 21 ft. lbs.

D: 120V/20 AMP DUPLEX RECEPTACLE:

  This convenience receptacle is used to power both 

  battery charger and the block heater. This circuit must be 

  fed from a GFCI fused circuit in the distribution panel. See 

  wiring instruction, this receptacle is split. On side is for the 

  20 amp block heater and the other is for the 15 amp 

  battery charger. Two individual power feed must be run 

  to this receptacle. A label is provide in the connection 

  panel to tell which side is which.

E: NEUTRAL TO GROUND LEAD LUG:

This lug is provided on the neutral terminal block to allow 

you to run a neutral to ground lead if you are using the 

generator in a stand alone application. This would be an 

application where there is not a distribution panel and 

no other ground to neutral bond in the wiring system. If 

a grounding wire is attached here, remove the floating 

neutral label in the panel. This will not be used when you 

are wiring a generator and transfer switch into an existing 

power system.

WARNING: EQUIPMENT DAMAGE

When installing a three-phase 240 Volt system, be 

sure you know which lead is the high voltage “wild” 

leg (208 Volt line to neutral). The generator normally 

carries the high voltage on the G2 lead.

All wires should be installed in rigid or flexible conduit 

(knockouts are provided in the control box).
