Resolution:
SCCR's = Short Circuit Current Ratings
2T = Two Tier
3T = Three Tier
'22k-10k' = Two Tier SCCR from Main(22k) to Branch(10k)
'25k-10k' = Two Tier SCCR from Main(25k) to Branch (10k)
Yes, there are 2T and 3T UL SCCR's listed for the QO and HOMELINE load centers.
The 2T SCCR is located on the Box label inside the load center enclosure and the 3T SCCR label is located on the load center cover. These labels will show all the appropriate 2T and 3T UL listed Series Short Circuit Current Ratings(SCCR) for either an integral or remote(upstream) protection with the load center branch breakers. Also, attached is a pdf data bulletin( document # 4100DB0301R03/14 )for the load center Short Circuit Current Ratings.
Two TIER SCCR's:
1) QO and Homeline Single Phase Main Breaker Load Centers supplied with a QOM1-VH (125A max) or QOM2-VH (225A max) main breaker are rated '22k-10k' SCCR Maximum standard, as a 2T SCCR.
2) QO Three Phase Main Breaker Load Centers supplied with a QDL main breaker are rated '25k-10k' SCCR Maximum standard, as a 2T SCCR.
NOTE: The factory installed QDL main breaker can be replaced with a QGL '65k-10k' SCCR or QJL '100k-10k' SCCR Main Breaker.
