Load Shed Kit Spec Sheet

DISTRIBUTED BY:
G11-124 (Load Shed Kit for RXT/RDT) 10/15c
Operation
D Loads are automatically added or disconnected based on generator capacity.
D The Kohler-patented load control system uses dynamic logic to prevent shedding important loads unnecessarily when air
conditioning, refrigerator, or water pump motors start.
D The load shed kit and generator communicate to provide smart power management. The time to shed loads decreases as each
load is shed to quickly adapt to critical power requirements.
D Load shed power level and frequency setpoint adjustments are possible only by using Kohlerr SiteTecht software, available to
Kohler-authorized distributors and dealers.
Load Monitoring with OnCuer Plus
D Using Kohler’s OnCuer Plus Generator Management System (sold separately), the customer can view load status (On or Off)
for loads connected to the Load Shed Kit.
D The Load Shed Kit outputs can be labeled in OnCuer Plus.

you need a 500 Amp CT for use with a 60RCL generator,
