The Square D Homeline HOM115 delivers what matters most for residential electrical work — reliable 15-amp circuit protection that trips faster than any competitor. At 10kAIC interrupting capacity, it handles fault currents safely while Square D’s exclusive Qwik-Open technology trips within 1/60th of a second. No other circuit breaker trips faster.
Skip it if you’re wiring a commercial panel that takes QO breakers exclusively. The HOM115 works only in Homeline load centers and CSED devices — not in QO panels or other manufacturers’ equipment.
Technical Specifications
Here’s what contractors need for code compliance and proper installation:
| Specification | Value |
|---|---|
| Amperage Rating | 15 A |
| Voltage Rating | 120/240 V AC |
| Number of Poles | 1-pole (Single Pole) |
| Interrupting Rating | 10 kA (10 kAIC) |
| Mounting Type | Plug-in / Plug-on / Bolt-On |
| Wire Connection | Accepts 2 wires |
| Width | 1 inch |
The standard trip mechanism protects against both overload protection and short-circuit protection. That 10,000 amp interrupting capacity means it’ll handle typical residential fault currents without destroying itself — critical when a short circuit occurs.
Installation and Compatibility
This breaker installs only in Homeline residential load centers. The plug-in mounting design means no tools needed — push it onto the bus bar until it clicks. The plug-on design makes for easy installation.
The terminal accepts 2 wires, letting you pigtail multiple circuits when code allows. That flexibility matters when you’re dealing with shared neutrals or adding circuits to existing boxes. Contractors appreciate its compatibility with existing Homeline panels — no adapter plates or special mounting hardware needed.
Professional Ratings and Availability
The numbers tell the story: 4.7 out of 5 stars across Home Depot and Lowe’s with 1,825 reviews at Home Depot alone. Multiple reviews show 5.0 out of 5 stars, indicating strong satisfaction among users.
In-stock availability shows 172 units with quick shipping — you won’t wait weeks for special orders. Ships in 1 business day from most suppliers. For Montana contractors dealing with remote job sites and tight schedules, that availability matters. Nothing worse than holding up rough-in inspection because your breakers are backordered.
Frequently Asked Questions
Q: Can I use the HOM115 in a Square D QO panel?
No. The HOM115 works only in Homeline load centers and CSED devices. QO panels require QO breakers — they’re not interchangeable despite both being Square D products.
Q: What’s the difference between 10kAIC and higher interrupting ratings?
The 10kA (10 kAIC) interrupting rating handles typical residential fault currents safely. Higher ratings matter more in commercial settings or homes with unusually large service entrances. For standard Montana residential work, 10kAIC meets code requirements.
Q: Does the HOM115 include arc fault protection?
The standard HOM115 doesn’t include AFCI protection. CAFCI/CAFI options are available in specific models like HOM115PCAFIC. Check your local code requirements — Montana follows NEC standards for AFCI protection in bedrooms and other specified areas.
Q: How fast does the Qwik-Open technology actually work?
Square D’s Qwik-Open technology trips within 1/60th of a second, with no other circuit breaker tripping faster. That’s faster than you can blink — critical protection when shorts happen.
