B-LINE QC2020D – Frequently Asked Questions
1) Is the QC2020D a two-pole 20 amp breaker or two separate 20 amp circuits?
The Eaton QC2020D is a two-pole breaker rated 20A at 120/240V, so it handles a single 240V load across both poles rather than feeding two independent 120V circuits. Use it where the load needs both hot legs, such as a high intensity discharge lighting circuit.
2) Does the QC2020D bolt into a panel or is it a standalone breaker?
It's a cable-in/cable-out device, meaning conductors land on both the line and load side of the breaker itself instead of the breaker plugging or bolting onto a panel bus. That makes it suited to enclosure or lighting-fixture mounting rather than dropping into a loadcenter interior.
3) Can I use the QC2020D on a 277V or 480V lighting circuit?
No. It is rated 120/240V only. A 277V or 480/277V HID lighting circuit needs a breaker rated for that system voltage, so the QC2020D is the wrong part for that panel.
4) Will a thermal-magnetic breaker nuisance trip on HID lighting inrush?
The QC2020D uses thermal-magnetic tripping and Eaton lists high intensity discharge as its application. The thermal element rides through the sustained warm-up current HID ballasts draw while the magnetic element still clears a short circuit instantly, which is why this type is specified for HID lighting rather than a purely thermal breaker.
5) Is the QC2020D UL Listed for commercial and institutional work?
Yes, the QC2020D carries a UL Listing, which is what most inspectors and facility specs require for an overcurrent device on a commercial lighting circuit. It's catalogued by Eaton as an industrial miniature circuit breaker in the QC type.
6) What exactly do I order to match an existing Eaton QC breaker in the field?
Order by the manufacturer part number QC2020D. Matching a QC-type unit means matching four things: QC type, two-pole, 20A, and the 10 kAIC interrupting rating. A QC breaker of the same amperage but a lower AIC is not a like-for-like replacement.
