Breakers

[Sebastian]

I've been trying to find out if this type of breaker can be stacked side by side or if there needs to be an air gap between them. CJ

Hmmm... I don't see anything in the product documentation that would indicate that they shouldn't be stacked.

Don't know if this helps but: http://www.vansairforce.com/communit...ad.php?t=35864

If it's not on the spec sheet one would think it isn't necessary. Presumably all the wiring has bee sized appropriately for the rated amperage so thermal effects are accounted for. Image search shows a lot of really tightly packed aircraft panels, plus the breakers in my house are all snug together.

If you're not comfortable with that seek an expert's opinion or message the manufacturer directly. An update would be nice if you find out anything definitive

Thanks for the response. Looks like y'all came to the same conclusion I did. But I have learned that the information on this forum is vast so I felt the smart thing for me to do was ask.
Thanks again.

A few years ago I bought a bunch of these at an aircraft surplus place and they were all attached to a bus bar with less than 1/16 of an inch between them. I believe they came out of an F16, so its probably ok to have them next to each other.

I think if they were the switch version, you might do some experimenting to make sure they were far enough apart that they felt right and didn’t interfere with each other based on the size of your fingers. But for plain breakers, I imagine close is fine. They shouldn’t get hot, especially if they’re the magnetic type (versus those that trip when they heat up).

If they are too far apart, they can easily rotate and bring the live parts into contact with the neighbouring circuit breaker.
I left a small air gap (like 1/8") and it's worked out fine.
I think you could also stack them hard against each other, although the clearances between terminals would become tight.

With my panel....the buss bars from ACS determined the spacing....they're stacked...all pull breakers.
