Doorbell Transformer Tape?

What is this tape on the doorbell transformer? I removed mine because it didn't look good and I thought it was a piece of plastic tape from packaging.

Did I mess anything up? I can re-use the same blue piece and wrap it back around if needed since it's a thin plastic type tape.

I have never seen tape used on a doorbell transformer. Is there printing on it? Maybe instructions?

In the link it's blue..... is that what you are talking about ?
Removing it won't affect the operation of the transformer.


Features an impressive output of 16V AC 10 VA from a standard input of 120V AC 60Hz
I couldn't resist posting this selling feature.

It probably was there to just identify type of transformer or just for look.

It will not interfere with junction of the transformer in anyway.

No printing. It just unravels. Mine is exactly the same but it's actually yellow.

Correct, but mine actually looks yellow like in this picture.

I want to make sure I haven't created a fire risk. I was able to re-wrap the yellow tape but it's loose. Will it affect anything if I completely remove it?

Are you 100% sure it won't interfere?

No risk. Maybe they did it to make it pretty. Honestly seen my share of doorbell transformers but never with tape.

Pete, maybe that tape holds in all that impressive power.<LOL>

Ray..... you beat me to it. SOMETHING has to hold that impressive power in.


The only possible use of the tape is to identify that transformer in a retail store. You buy this doorbell and you need the blue transformer or if you buy the dual chime you need the yellow transformer.

Ok, thanks for the help guys. I've got some dogs that stay at home when I'm gone and wanted to ensure I didn't install something that has risk.

This is exactly how mine looks.

And here is the new product being pictured on another website.

C905 Transformer -Accessories -Door Chimes - NuTone

I was able to wrap it back around loosely but it looks like I'll be removing it for good since you say it's safe!

Just a guess, but the tape may quiet the transformer a bit.

Well, I called a few electricians and they didn't really know what it was but all of them said it was just fine. One actually recommended I take it off to help the heat dissipate.

But I did have one say the tape helps the heat dissipate and I shouldn't have taken it off.

So...any feedback?

I've never seen such a lengthy discussion about a piece of inconsequential tape.

I've been doing electrical work for years and I've never seen tape on any transformer like that.

That tape does not have anything to do with how transformer works. Also, the body of that transformer is grounded.
That tape will not really help or harm with heat dissipation.
If anything, it might help keeping core of transformer from rusting, but not by much.

When I relocated my doorbell transformer a year or two ago I found that the rivets holding the laminations together wasn't tight. The result was the transformer had an annoying buzz. I used a Ty-wrap around it to hold it tight. I suspect the tape in this thread served a similar purpose.
