Published date: 07 May 2019

Issue:
Breaker can install for QON-42K

Product Line:
Load Center

Environment:
QO load center

Resolution:
QON-42K was built around 1970s and the breaker available during that time have ratings of 5KA and 10KA.
With regards to that one, there would be possibility that this device can only accept breakers with that rating.

If planing to install current design of breakers with 35K or 22K rating of breaker, for safety purposes, use it with current
design of load center.
