Broan-NuTone's Doorbell Transformer measures 2.54" x 2.19" x 2.65" and has a one-year limited warranty. Review: Reliable Transformer- Great for Ring Pro - This is a good transformer. It comes in a brown NuTone box and has a one year warranty. There is a small instruction guide for installations (1 bell, 2 bells, etc.). The transformer wires are in a threaded cylinder shaftess than 1” long. You insert this into a punch out on your juction box so you have no exposed wires. You then connect the common, load and ground (white, black, and green) to the corresponding wires in your junction box. If you are replacing a transformer you may first need to find the transformer unless it is by your panel. They tend to be in a straight lime from your doorbell (straigh line, shortest distance between points and all), so look in the attic, crawlspace, or basement in a straight line into the house from the doorbell, and near another power source like an outlet. Mine is in my crawlspace. You may find, as I did, that my ancient transformer was over-tightened onto the junction box. I ended up pulling off the box (POWER OFF! Or at least wires capped of you are a pro). This allowed me to turn the transformer unit and easily unscrew it. My only installation issue: this unit was slightly deeper than my junction box, and once I inserted it into the punch out hole it rested on the joist before the junction box. I just added some wood behind the junction box so both transformer and box are secure/nailed in to the joist. Installation itself is like 5-10 minutes. I spent more time finding my transformer and fussing with the old one’s “frozen” mount than I did the install. This one works great. Its 16v-30a. If you have a Ring Pro, you need this. Don’t get a 16v-10a or anything less than 16v-30a. If you have a long run to the doorbell (more than 60 feet from the transformer) use a 24v-40a with a Ring. I tried to get away with my old transformer for my Ring Pro and I did for a while then it died. Even before it died sometimes it would not fully ring my mechanical chime or drop WiFi connection with a low voltage message. Review: Excellent Quality - TLDR; Good quality transformer for wired doorbell camera and address light. Slightly larger Much better heat management. Barely warm compared to the too hot to touch cheaper one I got prior to this upgrade. Has a safety feature that shuts off if there is a fire hazard. Spend the money on this for peace of mind. Details: Unit itself is quality. It is made in china to Broan Nutone specs which is a US company. You would be hard pressed to find anything made in the US now This works with blink doorbell camera and to power my address light. Has sufficient juice and does not overheat. My old one which came with a house built in 2000 was a 16v 10va. It could not provide sufficient power to support a ring, blink, nest, arlo, eufy, Wyze doorbell camera. Bought a cheap unknown brand replacement with 16v 30va specifications but it got too hot to the touch. Normal to be hot. Some say 100 degrees is normal. Some say up to 120 degrees is normal operating temp. I can tell you it got way too hot and I was not comfortable sticking with it. Winded up paying double the price for this Broan Nutone unit and it is a significant improvement. No longer hot. Barely even warm. Size is bigger and I imagine it’s a better heat sink. So I guess size does matter. Minor notes Box came damaged and fins bent. Didn’t have to use them but bent them back using pliers for aesthetics. ## Features - EASY INSTALLATION DOORBELL: This doorbell transformer features an easy to install lock mount or wall mount, which reduces installation time by 25 percent.
