A non automatic circuit breaker is a switch, and will be better understood if you do a search on Google for a “non automatic circuit breaker”

Non-automatic circuit breaker ? A circuit breaker which has no automatic thermal overload trip

protection must be provided by an upstream overcurrent device.

Gordon:


I believe that the second sentence in the definition help us to understand: "Short-circuit and overload protection must be provided by an upstream overcurrent device." This means that there must be another overcurrect device ahead of this circuit

So heres my question…what good is it, other than to shut off service to the unit?

I say it is simple.


Recommend a licensed Sparky and go on your way.

Wait are you saying that 60 is the main for that panel????

Does not matter report is the same Sparkey!

I didn't see this until now.

The disconnecting means at the AC unit will satisfy the ready access to it, but now I smell a fish!

First thing is to look at the label on the unit to see what it says related to: "Maximum Fuse Size" or "Maximum Fuse Size or HACR Circuit Breaker"

The panelboard that you show, does it have an overcurrent device that is used to protect the branch circuit to the unit?

If so I would check to see if it is a HACR CB like I mentioned above if on the label.

Otherwise it is a HOT POTATO and you should do the typical recommendation to cover your a$%.

Harvey,


If I understand you correctly that 60A switch is at the unit, which is not over-fused and doesn't need to be an auto breaker since it is just being used to shut off power to the unit for servicing (disconnect or lock-out required by model codes). Then there should be a 40A max standard breaker at the panel to protect the wires and unit. If that is the case I don't see a problem.

But that looks like an FPE panel, which I think is an automatic flag for further evaluation by a licensed professional.

Hope that helps ... ![icon_wink.gif](upload://ssT9V5t45yjlgXqiFRXL04eXtqw.gif)

Harvey,


That is simply a molded case switch, just like putting in a non-fused pull out disconnect.

It offers no overcurrent protection and is there to serve only as a means of disconnect for serving the unit.

Like putting in a real heavy duty rated double pole switch (actually, not "like" that, that "is" what that is, a 60 amp rated double pole switch).
