The black wire is attached to the breaker - the white wire is attached to the neutral buss and the bare wire is attached to the ground buss. A sub panel requires when installing four wires -one red (hot 1) one black wire (hot 2) one white (neutral bus) and one bare (ground buss) If not wired by code it will not pass inspection and will probably trip.(NOT WORK) **Q: Will this AFCI/GFCI breaker detect both series and parallel arc faults?** A: Yes, it is Combination type AFCI. Also Class A GFCI, in one breaker. **Q: Will this breaker fit a Siemens ITE series C load center, Cat # G3030MB1200CU? Does it ship in 1-2 days or months?

Not sure how Amazon can offer them at half the cost of my husband's suppliers but I'm glad he decided to check. Looks like Amazon has a distributor status with Siemens though so he'll be checking everything on here now. ### ⭐⭐⭐⭐⭐ Worked as expected *by A***R on 4 July 2026* Genuine Siemans breaker. It's functioning normally and cost nearly $20 less than the big box stores. ### ⭐⭐⭐⭐⭐ Fantastic breaker - Easy replacement for Murray breakers *by S***. on 8 July 2025* Perfect replacement for my Murray circuit breakers. They work flawlessly and I upgraded 2 of these breakers (4 total) from AFCI to dual feature in about 10 minutes -- and given that I'm not an electrician, this was pretty easy. I tested both with the test button and an AFCI/GFCI testing tool on the receptacles and it was great. They are about the same size, so easily fit in the breaker box. It's only been about 30 hours since installing, but the breaker hasn't tripped, so I'm very happy. Note: It's important for safety: If you are installing these in a subpanel, make sure that your ground wires and your neutral wires do not go to the same bar in the panel -- it's very dangerous! Grounds go to one, neutrals (pigtails) go to the other! ## Frequently Bought Together - SIEMENS Q120DF 20-Amp Afci/Gfci Dual Function Circuit Breaker, Plug-in Load Center Style - Siemens Q115DF 15-Amp Afci/Gfci Dual Function Circuit Breaker, Plug on Load Center Style - Siemens QA120AFC 20-Amp Single Pole 120-volt Plug-On Combination AFCI Breaker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/282179257-siemens-q120df-20-amp-afci-gfci-dual-function-circuit-breaker](https://www.desertcart.sg/products/282179257-siemens-q120df-20-amp-afci-gfci-dual-function-circuit-breaker) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-22*
