To go back to the original post by TheMixFactoryNYC, if you are still considering extending the on/off switches and resets, you could consider fitting one or two of the CML Audio Power distribution cards (CML type PB1462). A photo and description can be found in the Sell/Buy section of our good forum, along with other CML cards that may be of use. For each power distribution output I have used a 2-pole circuit breaker to drive a relay. This ensures simultaneous disconnection of all 4 voltage lines under fault conditions, plus, the circuit breaker doubles-up as the bucket isolator switch. The breaker type used is similar to that found on the Ultimation power distribution panel. Trusting this is of interest.
Cheers,
Gareth.
