Hello, any insight is appreciated. I had my contractor install a transformer bought from HomeDepot to hardwire and charge my ring video doorbell 3+. At first, it was charging for a few seconds then burned out the transformer. We replaced the transformer and tried lower voltage at 8v and it burned out again. For the third time, I tried a different circuit and it burned out again.
Any ideas? Anyone experiencing the same thing? I read for this Ring Video 3+ a diode is not necessary.
