Overcurrent Error on Echo Relay Panel (ERP) Mains Feed


The display on the Echo Relay Panel (ERP) Mains Feed shows "Overcurrent Error". What does this mean and how can it be resolved?

Explanation of Issue

This error shows up when a 300w phase adaptive dimmer hits overcurrent or short circuit at 30A peak current, after which the dimmer should shut down and/or the breaker should trip.


Make sure the dimmer is not overloaded, and check the circuit wiring for shorts to ground and improper terminations.
