Using basic calculation of amps times volts equals watts you can see that a 15 amp circuit at 120volts has a capability of 1800 watts but a circuit should never be loaded above 80% so you have 1440 watts available. Most recessed light will not allow higher than a 75 watt bulb so assuming this take 1440 watts and divide by 75 watts to get 19.2 bulbs as you cant have a partial bulb go with no more than 19 lights. On a normal height ceiling of about 9 feet I never place recessed lights closer than 24 inches to the wall. As for interconnecting you just run a wire from one recessed light to the next. I would recommend that if you do not feel comfortable with the placement or wiring of these lights that you contact an electrician that specializes in lighting design to help you.
You can typically run around 10-12 LED recessed lights or 6-8 incandescent recessed lights on a 15 amp circuit, factor in the wattage of each light to ensure you do not exceed the circuit's capacity. It is always best to consult with a licensed electrician to determine the exact number based on your specific setup and other connected loads.
Remember you can now use Compact Fluorescent Lamps (CFLs), which take only 1/5 of the power of conventional light bulbs, without having to rewire your light fittings...
See the related question and answer about CFLs.
If you are following the NEC code (most popular in the USA) 14 guage wiring for general purpose lighting can not be protected at 20 amps. 15 amps is the maximum.
Designing for constant loading, a 15 amp circuit would allow for a total of 1440 volt-amperes (roughly equal to wattage)
The amount of fixtures that can be connected to this circuit depends on the MAXIMUM wattage rating of each fixture. For example, if the fixtures you are using are rated max 150 watts (even though you are only putting in 75 watt lamps for now) you must perform the calculation based on 1440 divided by 150 which is 9.6, or 9 fixtures.
If the maximum rating of the fixtures is 75 watts, then the answer would be 1440 divided by 75 = 19.2, or 19 fixtures.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

How many recessed lights can you put on a 20 Amp circuit breaker?
As a general guideline, you can typically install about 10-12 LED recessed lights on a 20 Amp circuit breaker. However, the exact number may vary depending on the wattage of the lights and any other devices connected to the circuit. It's recommended to consult with a licensed electrician to ensure proper installation and avoid overloading the circuit.
How many lights on 20 amp circuit?
Provided you use wire that is rated for 20 amps.
How many 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter?
Two 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter.
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 outlets can run off 1 gfi outlet?
Eight on a 15 amp circuit, tweleve on a 20 amp circuit, including the gfci receptacle itself.
How many recessed lights can you put on a 20 Amp circuit breaker?
As a general guideline, you can typically install about 10-12 LED recessed lights on a 20 Amp circuit breaker. However, the exact number may vary depending on the wattage of the lights and any other devices connected to the circuit. It's recommended to consult with a licensed electrician to ensure proper installation and avoid overloading the circuit.
How many 1.2 amp lights can a 20 amp breaker hold?
No more than 13 maximum on a 20 amp circuit.
Can six recessed lights of 50 watts be on a 15 amp breaker?
Should be fine if that is all that is on the breaker.
Can 20 amp breaker with 12 gauge wire handle 8 recessed lights?
Yes. I am assuming this is a residential question. A better answer is...if the 8 recessed lights draw fewer than 16 amps together, it is good.
How many lights on 20 amp circuit?
Provided you use wire that is rated for 20 amps.
How many 40 watt regular lights can you put on a 20 amp switch?
You can safely put 48 regular (incandescent) 40 watt lights on a 20 amp circuit. If at some future date you might place higher wattage lights in the circuit, you will want to limit the number of lights to 20.
How many 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter?
Two 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter.
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.
Can you use 14 gauge wire with a 15 amp breaker for recessed lighting?
To answer this question the circuits voltage must be stated. Find the total wattage of the lights, use the following formula. I = W/E, where W is the total wattage and E is the circuit's voltage.
How many 65w lights can be placed on a 15 amp circuit?
A 15a circuit can supply approximately 1650 watts, so 1650/65=25. I would stop at 20.
Can you power 7 recessed lights on one 15 amp breaker?
count your total amount of watts you are going to use (ie 7 bulbs 75 watts =525watt) watts divided by voltage 525 divided by 120vac = 4.375 amps, you can only load a circuit to 80% 15 amp breaker @ 80%=12 amps, you cannot exceed this by the electrical code.make sure you know what other loads are on the circuit unless this is a separate circuit. hope this helps..
