Interface Boards

Standard Interface Board

Connects to the Model RDC2 generator set/transfer switch controller. Includes a load control contact with a 5-minute time delay for starting selected loads after transfer to the emergency source, suitable for large motor loads.

Combined Interface/Load Management Board

An optional board that replaces the standard interface board. Available on single-phase standard and service entrance models (not on 3-phase or load center models). This board automatically manages up to six residential loads:

Up to four customer-supplied power relay modules can be connected for management of non-essential secondary loads.
Two HVAC relays are included for control of two independent air conditioner loads.

Load Management Features:

Disconnects non-critical loads to prevent generator overload (complies with NEC).
Monitors generator current and frequency to add or shed loads, preventing frequency drops that can damage electronics.
Allows the use of a smaller generator set.
Loads are added/shed based on generator capacity.
Dynamic logic prevents unnecessary shedding of important loads during startup of air conditioning, refrigerators, or water pumps (patent pending).
Smart power management through communication between the load management board and generator.
Load shed power level and frequency setpoints are adjustable via Kohler® SiteTech™ software (available to authorized distributors/dealers).

Priority Setting:

Loads are added and shed according to priority (Load 1 is highest, Load 6 is lowest).
Less critical loads can be automatically turned off when essential appliances are running.
Load priorities are hard-wired at installation.

Viewing Load Shed Outputs with OnCue® Plus:

Use Kohler's OnCue® Plus Generator Management System (sold separately) to view load status (On/Off) and remotely monitor load shedding/adding.
Load shed outputs can be labeled in OnCue® Plus.

Current Transformer (CT):

The combined load management board option includes a 400 amp CT for load monitoring. Larger diameter CTs (400A or 500A) are available for specific applications. See the table below for specifications.

Withstand and Close-On Ratings (WCR)

Service Entrance Transfer Switch Ratings

The service entrance transfer switch is factory-equipped with a normal source disconnect circuit breaker. Suitable for controlling motors, electric discharge lamps, tungsten filament lamps, and electric heating equipment, provided the sum of motor full-load ampere ratings and other load ampere ratings does not exceed the switch rating, and tungsten load does not exceed 30% of switch rating.

Switch Rating, Amps *	WCR, RMS Symmetrical Amps at 240 VAC
100, 150, 200	22,000
300, 400	35,000

* Continuous load current not to exceed 80% of switch rating.

Contactor Ratings with Coordinated Circuit Breakers

Single-phase transfer switches are UL listed at 240 VAC maximum. Three-phase transfer switches are rated at 480 VAC maximum. The following tables list contactor withstand current ratings (WCR) for 100-400 ampere non-service entrance rated switches with specific manufacturer's circuit breakers per UL and Canadian safety standards. These are suitable for controlling motors, electric discharge lamps, tungsten filament lamps, and electric heating equipment, provided the sum of motor full-load ampere ratings and other load ampere ratings does not exceed the switch rating, and tungsten load does not exceed 30% of switch rating.

The transfer switch is rated for use on a circuit capable of delivering not more than the RMS symmetrical amperes maximum shown in the tables below, but no greater than the interrupting capacity of the selected breaker.
