February 12, 20251 yr My issue is that I need to change the route of a wire into the red switch in the photos In the second photo I am pointing at the left to a cable out of the inverter that goes through the wall into the service void and then enters the back of the red switch from behind. The issue is that I need to re-route this cable out of the wall so that it enters the red switch from below as I show on the right. It should be a simple 5 minute job for me but I need to know how to isolate the PV so I don’t kill myself. On the photo to the left there is another black isolation switch. Do I just switch that off and also switch the red switch to off and is that all there is to it? Thanks PS I have asked the company who installed for us but they say they would need to send someone out to do this and they are not local

February 12, 20251 yr Author Thanks @ProDaveDave. Can you tell me how I test for dead? I have a multimeter but can't say I am too clued up on how you operate one!
