The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%.
If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments.
In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.

What circuit breakers will interchange with ITE EQB?
ITE EQB circuit breakers can typically interchange with Siemens EQB breakers, as Siemens acquired the ITE brand. Additionally, some GE circuit breakers may be compatible, depending on the specific model and application. However, it's crucial to verify compatibility based on the electrical system and local codes, as interchanging breakers can pose safety risks if not done correctly. Always consult with a qualified electrician before making any changes.
What circuit breakers fit into an old Gould Panel GQF40MBB?
The Gould Panel GQF40MBB typically accommodates Gould or Siemens type circuit breakers. Common options include the GFCI, AFCI, and standard thermal magnetic breakers, specifically the GQ series. When replacing breakers, ensure they are compatible with the panel's specifications and ratings to maintain safety and functionality. Always consult the panel's documentation or a licensed electrician for precise recommendations.
Will GE breakers fit a Murray panel?
No, they will not work. Use only Murray breakers for safety.
What is the name of a safety device that will shut off flow of electricity?
Devices used to open an electrical circuit are called OCPD's. (overcurrent protection devices) The most common are circuit breakers and fuses. In commercial motor starters they often employ another OCPD called a "heater" (UK thermal fuse) which is a metal strip which melts like the element in a small fuse when too much current (amps) go through it. They devices are in the circuit primarily to protect the wiring and devices they power. Circuit breakers such as in your home panel do protect you from a "shorted" circuit. Another safety and most common in residences are GFCI's or ground fault circuit interrupters (UK ELCB, Earth Leakage Circuit Breaker or RCD, Residual Current Detector) which come as both a receptacle (female plug) or as a circuit breaker.
Is there compatibility between Siemens breakers and other brands of circuit breakers?
Yes, Siemens breakers are generally compatible with other brands of circuit breakers, but it is recommended to consult with a professional electrician to ensure proper compatibility and safety.
What are the important considerations to keep in mind when selecting a circuit breaker box cover?
When selecting a circuit breaker box cover, it is important to consider factors such as the size and compatibility with the breaker box, the material and durability of the cover, the ease of installation and access to the breakers, and any safety regulations or requirements that need to be met.

What are the key features to consider when selecting an RV 30 amp breaker box for your vehicle?
When selecting an RV 30 amp breaker box, key features to consider include the amperage rating, compatibility with your RV's electrical system, durability, ease of installation, and safety features such as overload protection and circuit breakers.
What is margin of safety ratio?
Margin of safety ratio = margin of safety/sales revenue
Are there any specific requirements for circuit breakers in this electrical panel that must be met, such as the need for ITE compatible breakers?
Yes, there may be specific requirements for circuit breakers in an electrical panel, such as the need for ITE (Underwriters Laboratories Inc.) compatible breakers. It is important to check the manufacturer's guidelines and specifications for the panel to ensure that the correct type of breakers are used for safety and compatibility.
What are the potential safety hazards associated with old style fuse box circuit breakers?
Old style fuse box circuit breakers can pose potential safety hazards due to their outdated design and technology. These hazards may include the risk of electrical fires, overloading circuits, inadequate protection against electrical faults, and difficulty in quickly shutting off power in case of emergencies. Upgrading to modern circuit breakers is recommended to improve safety and reduce the risk of electrical accidents.

What should be kept handy in case of there is a short circuit?
A safety obeserver who has a wooden object to pull you from the live circuit. They must be trained in CPR and know where the circuit breakers are to deactivate the dangerous circuit in case of a mishap.
Why do some circuits have breakers?
They are a safety mechanism designed to open or break the circuit in the case of overload. They are usually used when a device on the circuit would be damaged or destroyed by an overload.
What are the key features and benefits of Cutler Hammer circuit breakers?
Cutler Hammer circuit breakers are known for their durability, reliability, and advanced technology. They provide protection against electrical overloads and short circuits, ensuring the safety of electrical systems. Additionally, Cutler Hammer circuit breakers are easy to install and maintain, making them a popular choice for residential and commercial applications.
