In this case Watts = Volts x Amps. If we assume 120 volts there is 1 Amp per bulb. Theoretically that would be 20 bulbs. However, for continuous operation you should be at only 80% of the load current or 16 Amps. So the answer is either 20 or 16 depending on if this is a math problem or a quiz for an electrician.

How many led c9 bulbs can you put on a 20 amp breaker?
The number of C9 LED bulbs you can put on a 20-amp breaker depends on the wattage of the bulbs. Typically, C9 LED bulbs use about 0.5 watts each. A 20-amp breaker can handle up to 2400 watts (20 amps x 120 volts), so you could theoretically use around 4800 C9 bulbs (2400 watts ÷ 0.5 watts per bulb). However, it’s advisable to limit the load to 80% of the breaker’s capacity for safety, which would allow for about 3840 bulbs.
How many 75 watt bulbs can be placed on track lighting with 20 amp breaker?
Theoretically a 75 watt bulb at 120 volts draws .625 amps. You would add the individual currents to determine maximum amperage. That would be 32 bulbs. However, you would then be right on the edge and breaker would likely trip often. You should de-rate to 80% of the breaker rating or 16 amps in this case. That would be 25 bulbs. You should also check to see if there is a maximum amperage or wattage rating on the track. Twenty Five bulbs will create quite a heat source.
How many bulb can conekt through 15 amp breaker?
Well it depends on the wattage of the bulbs. At 120 V, with power = current x voltage, you have power = (15 A) x (120 V) = 1800 watts. So if you have 100 W bulbs, then the maximum possible before the breaker should trip is 18 bulbs. It is not a good idea to operate near the limits of the circuit design, though.
Bedroom breaker keeps tripping out what can I do to correct this?
You need to identify specifically what is causing the breaker to trip. It could just be that you have to many devices or appliances on the circuit; or it could be a problem with the wiring, switches or outlets. Some steps to take. 1.) Unplug everything from the circuit. If it doesn't trip anymore you had too much plugged in. Identify what can be switched to another circuit. 2.) What device or appliance causes the problem? It is most likely something like a heater or something with a motor; or perhaps too many higher wattage light bulbs. 3.) If the breaker always trips when it rains, you may have a water moisture problem? 4.) If the breaker trips when nothing is connected it may be the breaker or a short in an outlet or switch.
What happens to the current measured as more bulbs added?
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.
Why would the breaker kick off when adding a run of lights with a switch at the end of the lights?
I really need more detailed information to answer your question. How many lights were added and what wattage bulbs are being used? For a 15-amp breaker, the maximum wattage it would handle would be around 1650 watts. This would be about 16 100-watt bulbs. Does your breaker trip immediately when you turn the light switch on? If you have an ohmmeter you can check the tripped breaker. Put one lead on the black "hot" wire coming from the breaker. Remember, the breaker must be off. Then put the other lead on the ground bar. If the ohm reading is very low, close to 2 ohms, then you have a direct short to ground somewhere in your wiring.
Did one leg of your 1950's 100A main breaker fry because it was overloaded by too many dedicated circuits?
It is possible that one leg of the 100A main breaker may have fried due to being overloaded by too many dedicated circuits in the 1950s setup. If the circuits were drawing more current than the breaker could handle, it could have caused overheating and damage to that leg of the breaker.
How many 100 watt lights per breaker?
I would use no more 14 100watt bulbs on a 15 amp circuit or 19 bulbs on a 20 amp circuit. You can calculate this by taking 80% of circuit amperage I.E 12 amps or 16 amps and then multiply by circuit voltage(120) to get 1440 watts and 1920 watts. Then take these values divided by bulb wattage(100 watts) to get 14.4 bulbs and 19.2 bulbs. Then round down for partial bulbs to get 14 bulbs and 19 bulbs.
How many flood lights on a 15 amp breaker?
It depends on the wattage of each bulb. Typically you only want to load your circuit to 80% of its rated capacity. Hence a 15 A circuit would be .8 x 15 Amps. Now if you had all 60 Watt bulbs and the supply voltage as 120 V then you could support 24 such bulbs. The key formulas are Voltage = Current x Resistance and Watts = Voltage x Current in your lighting example. However, if the lighting fixtures are rated for a higher value and you just choose to use 60 watts, you should size to the rated capacity of the fixtures on the circuit since someone else may later put in the maximum rated bulb.
How many 115 volt outlets could you run from a 20 amp breaker?
If you never plug anything into them, there is no limit. If the total current drawn from all outlets exceeds 20 amps, the breaker will trip.
How do you change bulbs in a 1997 Blazer?
There are many bulbs on a vehicle, need to know which bulbs you want to change.
How many watts do big bulbs use?
The usual criteria is that the larger the envelope size of the lamp the larger the wattage of the lamp. The terminology of "big bulbs" suggests that the lamp could be in the range of 400 watts.
