We received our stage lighting upgrade a couple of years back. We are now all LED, our old dimmer rack was replaced with a Sensor IQ Breaker/Relay panel. All was good until ETC recalled the breakers/relays last year. After we had them replaced with new breakers/relays they sent. Sense then we have had 4 of them fail in the on position, and had those four replaced a few weeks ago. Now two of those have failed in the on position. Working with our ETC installer, they are telling us this is a know problem. Has others had this problem. Any one know whet is being done to salve this issue? I don't like having to call the electricians in every few weeks to replace the breakers/relays.
