Product FAQs
6 answersIs the QO2030 a CTL or non-CTL tandem breaker?
The QO2030 is a non-CTL (Circuit Total Limiting) tandem breaker. It lacks a rejection clip and is designed for use in older Square D QO load centers built before CTL standards were implemented, which do not have notched pan rails.
Can I install the QO2030 in a modern Square D QO load center?
No. Modern QO load centers require CTL-rated tandem breakers, such as the QOT series, which feature a mounting cam or rejection clip. The non-CTL QO2030 is specifically for legacy panels that do not utilize rejection features.
How many panel spaces does the QO2030 require?
This tandem breaker requires only one standard 3/4-inch single-pole space in a QO load center while providing two independent circuits, one 20A and one 30A.
Are the 20A and 30A circuits on the QO2030 independent?
Yes, the QO2030 provides two independent single-pole circuits from a single breaker space. Each circuit has its own toggle and trips independently of the other.
Does the QO2030 feature a Visi-Trip indicator?
Yes, it includes the Square D Visi-Trip visual indicator. When the breaker trips, a red flag appears in the indicator window for rapid fault identification.
What is the difference between the QO2030 and QOT2030?
The QO2030 is a non-CTL breaker without a rejection clip, intended for older legacy panels. The QOT2030 is a CTL breaker with a rejection clip, designed to fit only in specific notched slots of modern QO load centers to prevent overstuffing the panel.
