Ok so i rna itno a sitution when installling and tsting some new Square D QO-CAFCI brekaers would not trip using the test button. I called Square D and found out that there is a problem with certain parts of the denver area that have a poor power quality that the CAFCI Breakers will not reconize and trip. Square D just found out about this problem and have redesigned the software to deal with the poor power quality issues. Square D is not issuing a reacll but will replace any CAFCI brekaers no charge but Square D has to send the Breakers from the factory as all the ones on the market were made prior to Square D finding the problem
 
Sure glad you posted that now i know where to look if there is a problem. Yep you'r right good ole "Excel". Waiting on them for the transformer to get power to this new building as usual.

I am not totally up to par with power qauilty and exacttly how it works. Square D told it is the sign wave signiture that the CAFI looks for and that the sign wave from excel ENrgy is in the area I am having probelms is not a normal sign wave / sign wave appears to square?
I understand that Square D has sent there eniginers to Denver and figured and discoverd the sign wave problems
Hell I am just a stuipd sparky not a good old Engineer.

This thread was started to record AFCI trouble. I thought mabey some had forgotten about it.

Read This.
 
Rio,

Very interesting development.

I'll second Frizbee Dog's comment. Please consider adding this to the "compilation thread" that Winnie started last month? Highlight your opening post text, then right click and copy. Next, left click on the link here, "compilation thread", and then use the Post Reply button and paste the copied text. You can add more or edit, but it would be cool to see your story added there.

When you click on the link to Winnie's post, I expect you'll open a new window, so you can go back to this thread and highlight your second post to carry that text to your reply as an additional paste.
