HACR Breakers Everywhere

[tonype]

Can HACR breakers be used in an entire panel?

 

[iwire]

Yes and I think all new breakers are HACR

 

[Mgraw]

Yes, I read on SqD's website the standards breakers must meet exceed the requirements of HACR breakers.

 

[jim dungar]

UL included HACR as part of their normal breaker testing, maybe 10-15 years ago. At that time putting the term HACR on the breaker became optional.

One of the 20 A breakers looks tripped to me.

In a word yes. Any breaker that satisifies UL 489 Listing is also suitable for HACR use.

Could you go back and turn the tripped breaker back on to make our friend (K8MHZ) happy.
Thanks.

Notice the ITE tandem on the top left, but challenger went out of business a while ago, it was common to find a 10/20 panel full of tandems, but what an expensive way to go.
I didn't think you could use the spaces opposite from the main? and some panels had the buss cut away so if you tried it wouldn't make contact, had a few of those DYS service calls:blink:

That said, some inspectors will still require the HACR label on the breaker for use as such.

For many companies, you need to special order 'labeled' breakers.

Wouldn't it be nice if inspectors would keep abreast of the standards (i.e. UL 489) they insist be followed.hmy:

Heard that Jim! In the past we have had to special order " labeled " breakers for one particular inspector. :rant:

Good observation - it was tripped - labeled garbage disposal, but none present (a loosely installed junction box sits under the kitchen sink). It was "flagged" for the buyer.

One of the reasons why I hang out at this forum (as well as forums for plumbing, heating, cooling, ventilation, insulation, structural, etc) - excellent place to learn stuff.
