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.

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 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.

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 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 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.


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..
