Can you buy just a circuit breaker?

Yes, you can purchase a circuit breaker just as you can purchase a wall switch. Big box home stores and hardware stores carry circuit breakers. You should know that they can be a bit expensive, and they are not returnable. Additionally, there are several different types of breaker, and if you have an older electrical panel, you might have to do a bit of calling around to locate a breaker that is made for that setup.

The last thing you need to know is that experimenting with electricity by tinkering with a home electrical distribution system can be fatal. Electric shock can kill the careless or less-than-knowledgeable do it yourselfer. Or an electrical fire can damage the home, and endanger anyone home at the time. Damage to equipment that is incorrectly wired is possible, but that pales compared to the other two hazards.

Replacing a breaker is not extremely difficult, but exposes the worker to hazards that must be managed. Opening the mains breakers to completely de-energize the panel busses is the smartest route. Naturally an exact replacement will have to be chosen, particularly as regards the trip rating. And if you're adding a breaker to a panel to accommodate a new circuit, you'll have to have done the math to insure that the panel is rated for the additional circuit. That's in addition to insuring all that the other wiring meets code and is done in a workmanlike manner.

Shortcuts or "amateur" work on electrical systems cause fires and can kill people. No judgment is passed, but the cautions cannot be overstated. A professional consultation is the best idea, and "experimentation" is discouraged.

What do I do if there is no circuit breaker for outdoor light?

If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.


Can circuit breaker isolate circuit?

That's just what a circuit-breaker is designed to do - Isolate a circuit from the rest of the system.AnswerNot necessarily. A circuit breaker is a protective device, designed to disconnect circuits in the event of an overcurrent due to overload or short circuit. While a low-/medium-voltage circuit breaker, of course, can be used to open a circuit, it does not necessarily provide isolation. In general, isolation requires a visible break in the circuit; as a circuit breaker's contacts are enclosed, a visible break is not possible.In the case of a high-voltage circuit breaker, the device is used to open a circuit but does not isolate that circuit from the supply. Isolation must be provided using separate,usually non-loadbreaking devices (i.e. devices which are not designed to open a live circuit) called isolators (UK term) or disconnector (US/Canadian term), which provide a visual break in the circuit. The exception to this is a racking-type circuit breaker which, after it has been opened, can be racked down from the circuits to provide a visual disconnection.

No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
