Issue:
Tandem breakers usage clarification
Product Line:
QO PON Load Centers
Cause:
Difference in CTL and Non-CTL type breaker usage
Resolution:
All Standard QO plug-on circuit breakers are listed for use with PoN Load Centers. The only exception is associated to QOT (CTL) style tandems which are NOT compatible and therefore not listed for use with the QO PoN architecture. QO PoN Load Centers are listed for use with QO Tandem Circuit Breakers (max 20A, non-CTL) as shown in Table 1.1 below. Using the prefix QO (max 20A, non-CTL) style tandems, increases the number of circuits vs. spaces a Load Center will allow. QO PoN Load Centers packing label(s) reference the maximum circuits allowed when using QO (max 20A, non-CTL) style tandems. The QOT (CTL) tandem breakers remain active for use with fixed main Load Centers (for example: QO816L100DF) and existing legacy (non-PoN) QO Load Center installations.
