I’m in the process of refinishing my basement, and I’ve installed the breakers. My panel uses Square D QO breakers that have a window that shows red when the breaker is in the tripped position. Breakers are then reset by turning fully off and then on.
One of the new breakers shows just a tiny bit of red in the window when it’s in the “on” position. It doesn’t instantly trip when turned on. It does this even with the breaker removed from the panel. The breaker switch moves fully to both on and off positions.
Is this something to be concerned about?
When in doubt return it and replace. Peace of mind is worth the effort.
Agreed, especially if you can get a refund or free replacement.
It sounds like it’s functioning correctly and likely just a small cosmetic issue. I probably wouldn’t worry about it.
Thanks! I thought it might be, but I was unable to find anything on the internet to confirm.
Breakers are just one of those things I’d rather not be like “it’s probably fine” and then find out it’s not, y’know?
Breakers trip internally, the switch is just there to reset it.
You can lock them on and they still trip.
It’s just a cosmetic defect. But if you’re really woried about it then you could just replace it. Breakers aren’t that expensive.
Thanks. Thought as much, just wanted to be more certain.
It is absolutely just more cost effective, safer and better piece of mind to just replace the breaker. I’ll take that route 99.99% of the time.
If you feel adventurous, there are a couple of ways to test that breaker without proper test equipment. The risks could be zero OR you blow your face off and burn your house down.
Find an open outlet at tap live to ground. This will produce some natural and organic indoor fireworks, but it should trip the breaker. If it doesn’t, there is a small risk of welding the wires together and creating a very strange short condition, turning that entire circuit into a new heat strip. (Free money!)
Find two 1800W space heaters and together, on the same circuit, they should trip the breaker as well. (Breakers should be rated to at least 1800W.) This is problematic as well and I’ll explain. There is something magical about space heaters as I have seen 2 or 3 run off of the same circuit before. I suspect that if a breaker is slowly warmed up due to heavy load it will change its characteristics, causing it to only trip at higher loads. (Absolute speculation on my part!) By default, I would replace the breaker if I saw that kind of load. Extended, and higer heat cycles will eventually damage the breaker.
I know you have gotten quite a few answers already, but I thought I would help ease your worries. I work in industrial maintenance, and have been in quite a few square d panels. This is fairly common, and not indicative of an issue with the breaker. Nothing to worry about.
Does the switch sit tightly in that on position, or is it a little loose? If it’s tight, I wouldn’t worry about it, myself.
It’s tight. It doesn’t feel any different than any of the other breakers.
