Common sense with electrical systems dictates that current in a circuit be limited to 80% of nameplate (20A). The number of 150W lamps will be limited to 12 in this scenario. This answer can be superseded by local ordinance.

To answer this question a voltage needs to be stated. W = Amps x Volts to find total circuit wattage. Then divide the bulb wattage into total circuit watts.

How many 60 watt bulbs can a 15 amp handle?

A 15 amp circuit can handle approximately 8-10 60 watt bulbs. Each 60 watt bulb draws 0.5 amps of current, so you divide the circuit's amp rating (15 amps) by the current draw per bulb (0.5 amps) to get the approximate number of bulbs it can handle.


How many watts are in 100 2.5 volt bulbs?

This question does is not answerable. A watt is a volt times an amp. With out knowing how many amps the bulbs use there is no answer.


How many amps would a 150 watt bulb draw in a 120v circuit?

1 amp


How many amp circuit do you need for a 110 volt 1500 watt hot water heater?

For a 1500 watt hot water heater connected to a 110 volt power source, you would need a 13.6 amp circuit. It is recommended to use a 15 amp circuit to provide some safety margin.


How many 100 watt bulbs can a 110 volt circuit handle?

To answer this question, you need to know how many amps the circuit that is connected to the light bulb can handle. For home applications with a 15 amp circuit and no other loads connected you get: Power = Current * voltage, Substituting the known information yields: power = 15 amps * 110 volts, which is 1650 watts of total capacity. You have 100 watt bulbs, so: 1650/100 = 16.5 bulbs If your circuit is other than 15 amps, or if there is additional loads on the circuit, you must adjust the current or total capacity accordingly


How many 100 watt lights per breaker?

It is generally recommended to have a maximum of 12 outlets/lights on a 15 amp circuit breaker. With each 100 watt light consuming 0.83 amps, you could safely have around 18 lights on the circuit. It's always best to consult a licensed electrician to ensure safety and compliance with local regulations.


How many watts on a 40 amp circuit breaker?

about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)


How many sixty watt bulbs could you connect in a bedroom?

The voltage of the bulbs is needed to answer this question. If we assume the voltage is 120 then the maximum wattage allowed on a 15 amp circuit is 1800 watts before the circuits over current device will trip. 1800/60 = 30 bulbs. To be certain that the circuit does not trip, only connect 29 bulbs to the circuit. If the circuit is considered as a continuous load then the load rating has to be reduced to 80% capacity. 1800 x .8 = 1440. With this de rating the number of bulbs allowed on the circuit would be reduced to 24 bulbs. This circuit would have to be a dedicated circuit and could not be combined with receptacles which could vary the load depending on what is plugged into them.


How many 150 watt flood lights can be on a 20 amp circuit?

The voltage needs to be known to give an answer to this question.


Number of 70 watt lights on a 15 amp circuit?

You can safely connect up to 10 70-watt lights on a 15 amp circuit. Each 70-watt light draws 0.58 amps, so you would not exceed the circuit's 15 amp capacity with 10 lights.


How many 50 watt lights on a 15 amp circuit?

50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.


How many 25 amp bulbs fits 105 watt transformer?

Approximately 4 bulbs would fit a 105 watt transformer, as each 25-amp bulb consumes around 26.25 watts.
