Manufacturers and engineers working with compact breaker panels rely on precise markings such as 7110gd 2p 15a 125v nema 515 to verify compatibility and safety. This concise code identifies a specific North American molded-case circuit breaker and outlines its electrical and physical characteristics.
Across residential upgrades and light commercial installations, understanding each element of this identifier reduces installation mistakes and ensures compliance with local codes. The following sections break down the technical details, application scenarios, and common questions around this breaker designation.
| Code Segment | Meaning | Typical Use | Safety Notes |
|---|---|---|---|
| 7110gd | Manufacturer series and frame size | Load center and panel integration | Confirm compatibility with panel bus bars |
| 2p | Two-pole construction | 240V circuits | Interruption of both hot legs simultaneously |
| 15a | Rated current | Lighting, receptacles, small appliances | Do not exceed 15A continuous load |
| 125v | Voltage rating per pole | Standard North American branch circuits | Matched to circuit voltage requirements |
| nema 515 | NEMA enclosure and mounting type | Panel field wiring and enclosure fit | Verify cutout dimensions before installation |
7110gd 2p 15a electrical specifications
The first segment of the identifier, 7110gd, defines the product family and physical frame within the manufacturer’s catalog. Selecting a breaker with this exact frame ensures proper fit and electrical performance inside standard North American panels.
Two-pole operation and 240V applications
The 2p notation indicates that the breaker interrupts both energized legs of a 240V circuit, providing balanced protection for appliances and equipment. This configuration is common in HVAC components, electric water heaters, and large kitchen devices where dual-pole safety is required.
15 amp capacity and circuit wiring requirements
A rating of 15a means the breaker can safely carry 15 amperes continuously without nuisance tripping, subject to ambient temperature and enclosure conditions. Wiring for this protection typically uses 14 AWG copper, although local amendments and future load growth should be reviewed by a qualified installer.
NEMA 515 enclosure and panel integration
NEMA 515 defines the enclosure characteristics and mounting footprint, ensuring the breaker matches slot dimensions and mechanical clearances inside field panels. Verifying NEMA 515 compatibility prevents installation delays and supports consistent labeling, which is essential for maintenance and inspection.
Installation practices and field application guidelines
Correct installation of a 7110gd 2p 15a 125v nema 515 breaker involves torque verification, proper bus bar alignment, and labeling at the panel face. Electricians should pair the breaker with appropriately rated conductors and coordinate with local authorities having jurisdiction to confirm regional code acceptance.
Selecting the right breaker for your panel
- Confirm that the panel brand and slot design are compatible with the 7110gd 2p 15a 125v nema 515 footprint.
- Verify local code amendments and obtain required permits before replacing or installing the breaker.
- Use correct wire gauge and termination torque to reduce voltage drop and thermal risk.
- Document the breaker identifier and circuit purpose on the panel face for future service work.
- Schedule periodic inspection of connections and label integrity during routine maintenance.
FAQ
Reader questions
Can this breaker be used for a 120/240V split-phase residential panel?
Yes, the two-pole, 125V rating matches standard split-phase residential services when applied to a 240V circuit such as a dedicated appliance or subpanel feed.
What wire size should I pair with a 15 amp 2-pole breaker?
For copper conductors, 14 AWG is common for 15A, while aluminum typically requires 12 AWG; always confirm with local amendments and consider ambient temperature derating.
Is this device suitable for use in a small workshop subpanel?
Yes, when the subpanel is rated for the amperage and voltage, and the enclosure matches NEMA 515, it can protect workshop circuits with lighting and general-purpose receptacles.
Do I need to verify compatibility with my specific panel brand before ordering?
Yes, check the panel manufacturer’s compatibility lists and physical slot dimensions to prevent fitment issues and to ensure proper electrical and mechanical engagement.
