I know this sounds strange, but where do I find information on why breakers need handles?

I know the question would arise on how you would lock them out, without handles, but I think I have that figued out. Where do I find this requirement?

UL listing?

Mmmmmmmmmm, No Handle. no ability to reset and close the breaker. Then the breaker must be replaced when it trips.
Go with fuses as they are easier to replace.

I guess it depends too on your definition of a "circuit breaker". When I look up the definition in Article 100 I would say "No circuit breakers don't have to have handles". It could be a device that will be resetable by pushing a button.

How about this circuit breaker?
It doesn't have a handle and it resets itself.

Hmmm. thermal reset?? Forklift??

OK, Dave.....
You talking about 'big' breakers with removable leverage handles??? Or are you talking about 'small' cb's with toggle type handles??

NO, I'm not being a wise guy, and not because I owe you one; I just don't get your drift.

Stay dry!

John, I was pondering a thought that had to do with digital breakers, and using X-10 technology. I had the thought that a breaker had to have a handle for some reason..

I am thinking about a digital push button,(on-off) with a key for lock-out....

Square D makes 'Power Link' breakers which are otherwise normal breakers but have the ability to open or close the circuit by remote means.

However the handle does not move, the remote opening and closing is done internally.

I can not imagine that in the near future we will be seeing 'handless' breakers.

To many accessibility issues along with tradition.

if memory serves me right, UL standards require that a breaker have some means of indicating a trip, as well as re-setting it. As another mentioned, there are breakers that use a push-button for this, rather than a handle.
