While smoke detectors draw very little power, you can only put a certain amount on a circuit. This is determined by the manufacturer's specifications which must ALWAYS be consulted. Some manufacturers only allow 9 per a circuit, others 11, and some brands may even be more. If you were to try to put more than the designated amount on that circuit, the detectors would not work as they were designed to, and most certainly would not pass a fire inspection. If it is a large house that a system is being installed in, a low-voltage system is always the best way to go.
As a side-note, just because a given device only uses so much power, the National Electrical Code (NEC) still has guidelines that MUST be followed. A "continuous load" as defined by the NEC is something that stays on for more than 3 hours at a time - and it states that you can't load a circuit more than 80% of its capacity.
Lighting is a perfect example, so let's use light bulbs as an analogy.
A 60-watt light bulb uses .5 amps at 120 volts (60 watts divided by 120 volts is .5 amps). Therefore, on a 15 amp circuit, you would think that you're able to put 30 of these 60-watt light fixtures on a circuit, right? Actually, no.
Lighting is most certainly considered a continuous load, because you definitely leave your lights on for more than 3 hours at a time. Therefore, per the Code, that circuit can only accept 80% of its capacity because of the continuous load, leaving you with 12 amps (80% of 15). This means that you can only use 24 of those 60 watt fixtures, not 30.
Wiring is not a hobby - always hire a licensed and qualified electrician.
in one zone how many smoke detectors
Many smoke detectors contain americium.
it senses smoke and makes a loud sound to wake you up. Many places mandate that homes have smoke detectors.
BRK Smoke Detectors have long been recognized as one of the top brands when it comes to smoke detectors and many other types of gas detectors. Because of their tried and tested construction, BRK smoke detectors are able to stand up to years of abuse without having to undergo a whole lot of maintenance to stay in working order. This is why many companies tend to use BRK smoke detectors when they need to cover a large area of industrial use with a smoke detector that is guaranteed to provide years of carefree service. If BRK smoke detectors are trusted for this, they can be trusted for anything.
there are 4 kinds of circuit breaker. Such as, ACB,OIL CB,VCB & SF6
There is no current in a 60A circuit breaker. The above circuit breaker is a 2 pole circuit breaker that will trip when more than 60 AMPS is being drawn through either of the 2 poles.
Many smoke detectors use Americium-241, which emits alpha rays, to keep air ionized.
Ideally, a smoke detector for every room should be in place.
Many times, a circuit breaker may trip when the circuit is overloaded. Before plugging in electronics and appliances, you should check to ensure that the circuit can handle the load.Ê
Usually a 15 or 20 amp breaker is sufficient
Many different types of sensors:heat detectorssmoke detectorstemperature rise detectorsflame detectorswater flow detectorscarbon monoxide detectorsvolatile organic compound detectorsamong others
a. Americium-241 Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.
too many volts
many smoke detectors contain:
A maximum of 40
The cost of a circuit breaker depends on the brand that you get and how many amps and how much voltage is running to the breaker. The average price is between 20 to 50 dollars.
There are many circuit breakers in your 1983 El Camino. There is a circuit breaker box just below the dashboard on the far left side. The circuit breaker box should have a cover. Once the cover is removed the circuits will be revealed.
You can find the wiper and washer circuit breaker at most large retail stores. You can also find the circuit breaker at many local hardware stores.
No, it is an inherent part of the circuit.Further AnswerIn simple terms, a circuit breaker is a switchwhich is designed to break a fault current, which are many times greater than load currents. More specifically, a circuit breaker is a protective device designed to automatically interrupt overload currents due to overloads or short circuits.
There are three coils in Air circuit breaker.. 1.Solonoid coil 2.Moving coil 3. fixed coil
Legally there is no law on this (under UK law) However, you will know if there are too many as this will cause the breaker to trip 'breaking' the circuit, and thus telling you there are too many =============== In the US, circuit conductor size and circuit breaker size are calculated before installation. If you are doing modification you should get the help of a professional in calculating what your installed wiring will safely allow.
Are you talking about radar detectors? If so, they are illegal in many jurisdictions and WikiAnswers does not give information about illegal activities such as using radar detectors. If you are not talking about radar detectors, the please restate the question, giving more specifics about what kind of circuit you are talking about.
All circuit breakers are overcurrent protection devices, which are used to disconnect a circuit in the event of a prolonged overload current or a short-circuit current.An air circuit breaker is one of many types of high-voltage circuit breaker. It uses a blast of compressed air to extinguish the arc formed when its main contacts open. In some cases, air pressure is also used to operate the mechanism that opens and closes the main contacts.
A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.
