Never saw a 10 amp breaker. Is there such a thing?

Dave,


I don’t believe I have ever seen a ten amp breaker icon_exclaim.gif

This is a common test question on the NAHI CRI exam, NHIE, the old Arkansas or other State Tests, etc. In the order that you have written the question, there is no correct answer that matches the same order and someone taking this as a test question would be graded as wrong if the put the 1 answer that has the correct sizes but in incorrect order.

That’s what I was trying to say in my previous post, only you said it better Dan. It appeared to me like there was no completely correct answer because of the order they were in.

Dave,


Shouldn't that 10 amp really be 15 amp for question B?

There is one that matches, although it is flipped around.


Of course there are hundred exceptions to this question ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif) , but I will assume NM cable on typical multi outlet branch circuits.

Exclude motors, HVAC, taps etc.

Conductor sizes relate as much to the load than the breaker size.

I don’t see where the question is confusing, other than the 10amp breaker.


All the other breaker = wire sizes compute.


To be honest, as a newbie on this site, I am suprised to see so many incorrect answers on this textbook question.

You are out inspecting and find an HVAC unit fed with 12 AWG on a 35 amp breaker.

Is this a violation?

This is a text book question. ![icon_wink.gif](upload://ssT9V5t45yjlgXqiFRXL04eXtqw.gif)

Mr. Badger,


Shouldn’t you wait to post that as A “Question of the Day”



But to answer your question, I would say yes, since a 12 AWG requires a 20 amp breaker

Hi 55, Please do not call me Mr., Bob is is fine. icon_smile.gif


The answer to my question could be yes or no, I did not give enough info to answer the question with certainty.

That was the point, many electrical questions are not so easy.

me if you want more info, I do not want to drift this thread on Dave B or the others. ![icon_smile.gif](upload://b6iczyK1ETUUqRUc4PAkX83GF2O.gif)

Bob B,


That would depend on the nameplate rating on the unit. ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)

Kevin,


If order matttered in the answer, there would not be a correct answer!

, indeed, matter. If there was a 10 amp breaker involved, then #14 would be fine.


Reversed order of answer is incorrect, IMO, as the question gets read in sequece, so the answer needs to follow that same sequence...

The NEC doesn’t recognize a 10 amp breaker, only 10amp fuses. It does state that the use of “non-standard” amperage ratings on breakers is permitted. icon_confused.gif
