If you install more than one device in the same wallbox, you may need to de-rate or reduce the load that each device can control. De-rating may be necessary based on the type of bulb you are controlling. Incandescent and Magnetic Low Voltage bulbs require de-rating. De-rating is not required when using dimmable LED or dimmable CFL bulbs in multi-dimmer installations. Refer to the de-rating chart in the instructions for maximum load per dimmer.
