hay guys, set my display up last week, running a few tests. all has been running great until I turn on this afternoon only to find one of my arches on fire. Pics attached. Im running my entire display off 3 different main 240v outdoor power points. Ive had an electrician install them for me and upgrade the lines to 30amp with separate fuses to the house in the meter box. Funny thing about this fire was I wasn't running any lights, it was just powered up. Ive checked volts, both from the PSU and at the arch that caught fire. 13.25-13.5v. The strips are ws2811 12v. I have turned the PSU up a bit as I was losing voltage down the arches. In my pics, you'll see 3 arches. the 3rd arch has injected power. but its the 2nd arch that caught fire. I use 2 plugs to connect strips. GND and Data plug and a GND and Positive plug. What have I not done??. could it be a faulty strip. or should I be inserting in line fuses from the PSU's. surely having the PSUs at 13.25v wouldn't have caused that?? it was pretty hot. melted the PVC piping as you'll see. Think I'll keep that power off until someone advises me of what Ive done wrong and or missed.
