1. Introduction
This manual provides essential information for the safe and effective use of the Cutler Hammer CH115 1-Pole 15-Amp Circuit Breaker. This device is designed for use in Cutler-Hammer load centers and functions as a replacement circuit breaker. It is rated for 120 volts and 15 amps, providing protection for electrical circuits.
Typical applications for this breaker, supporting up to 1,800 watts, include fixed lighting circuits, general branch circuits, wall receptacles, electric motors (ranging from 1/4 hp to 1/2 hp), attic fans, and garbage disposals. These are suggested applications; always verify compliance with local electrical codes before beginning any electrical project.

2. Safety Information
WARNING: Electrical work can be hazardous. Installation, maintenance, and troubleshooting of circuit breakers should only be performed by a qualified electrician or authorized personnel. Failure to follow these instructions can result in serious injury, death, or property damage.
- Always disconnect power at the main service panel before working on any electrical circuits or equipment.
- Verify that the power is off using a voltage tester before touching any wires or components.
- Adhere to all local and national electrical codes and regulations.
- Use appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses.
- Do not use this circuit breaker if it appears damaged or has been subjected to moisture.
3. Setup and Installation
The Cutler Hammer CH115 circuit breaker is designed for plug-in mounting within compatible Cutler-Hammer load centers. It requires one 3/4-inch space in the load center.
Installation Steps:
- Power Disconnection: Ensure the main power to the electrical panel is turned OFF at the utility meter or main disconnect. Confirm zero voltage with a multimeter.
- Panel Access: Carefully remove the cover of the electrical load center.
- Identify Slot: Locate an available 3/4-inch slot in the bus bar of the Cutler-Hammer load center.
- Connect Wire: Connect the circuit wire (hot wire) to the terminal screw on the circuit breaker. Ensure the wire is stripped to the correct length and securely tightened.
- Mount Breaker: Hook the rear of the circuit breaker onto the retaining clip in the load center, then firmly press the front of the breaker onto the bus bar until it clicks into place.
- Replace Cover: Reinstall the load center cover.
- Restore Power: Turn the main power back ON.
Note: If you are unsure about any step, consult a qualified electrician.
4. Operating Instructions
The CH115 circuit breaker features a toggle switch for manual operation and visual indication of its status.
- ON Position: Pushing the toggle switch fully towards the "ON" label (typically upwards) connects the circuit, allowing electricity to flow.
- OFF Position: Pushing the toggle switch fully towards the "OFF" label (typically downwards) disconnects the circuit, stopping the flow of electricity.
- Tripped Position: If an overload or short circuit occurs, the breaker will automatically trip. The toggle switch will move to an intermediate position, usually between "ON" and "OFF", or sometimes fully to "OFF" depending on the design and fault. This indicates that the circuit has been interrupted for safety.
Resetting a Tripped Breaker:
- Identify Cause: Before resetting, try to determine the cause of the trip (e.g., too many appliances on one circuit, faulty appliance). Unplug or turn off devices on the affected circuit.
- Full OFF: Firmly push the breaker's toggle switch all the way to the "OFF" position. You may feel a slight click.
- Full ON: Then, push the toggle switch all the way to the "ON" position.
- If the breaker immediately trips again, do not attempt to reset it repeatedly. This indicates a persistent electrical fault that requires professional attention.
5. Maintenance
Circuit breakers generally require minimal maintenance. However, periodic inspection can help ensure continued safe operation.
- Visual Inspection: Periodically inspect the circuit breaker for any signs of physical damage, discoloration, or burning. If any damage is observed, the breaker should be replaced by a qualified electrician.
- Panel Environment: Ensure the electrical panel area remains clean, dry, and free from obstructions. Do not store flammable materials near the panel.
- Tight Connections: Over time, wire connections can loosen. A qualified electrician can periodically check and tighten terminal screws within the load center.
Note: Do not attempt to open or repair the circuit breaker yourself. Internal components are not user-serviceable.
6. Troubleshooting
If your circuit breaker is not functioning as expected, consider the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Breaker trips frequently | Overloaded circuit (too many devices), short circuit, ground fault, or faulty appliance. | Reduce load on the circuit. Unplug appliances one by one to identify the faulty one. If problem persists, consult an electrician. |
| Breaker will not reset | Persistent fault (short circuit, ground fault) or internal breaker damage. | Do not force the breaker. Ensure all devices on the circuit are unplugged. If it still won't reset, contact a qualified electrician immediately. |
| No power to circuit, breaker is ON | Loose connection, faulty wiring, or internal breaker failure. | This requires professional diagnosis. Contact a qualified electrician. |
For any issues not resolved by these steps, or if you are uncomfortable performing any troubleshooting, always contact a qualified electrician.
