Best Answer

Assuming only lights are on the circuit and no outlets you can run 1440 watts on the 120 volt circuit. So if the lights were each pulling 75 watts you can install no more than 19.

If there is nothing else on the circuit then you could easily install 15. If there are outlets on the same circuit then try and keep the total of outlets and lights to a maximum of 15. But in reality the number of devices depends on how many amps each device pulls. Add up the amperage of the recessed lights you are going to install and then add any outlets and what may be plugged into them to get the number you can install. A 100 watt light bulb will draw about 1 amp. So you can easily have 15 on a 20 amp circuit.

Depends on if it is a 15 amp or 20 amp circuit. You can install no more than 12 outlets on a 20 amp circuit or 9 outlets on a 15 amp circuit. You can install no more than 1920 watts on a 20 amp lighting circuit or 1440 watts on a 15 amp lighting circuit. If it is a 20 amp circuit I would not install any more than 8 outlets and 4 lights. If it is a 15 amp circuit I would not install any more than 6 outlets and 3 lights. This only applies to living spaces like bedrooms, living rooms dining rooms, and not to kitchens, baths, utility rooms, garages, etc.

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.

It would be quite unusual to have a single 60 amp circuit with outlets and lights. You would have to use very heavy wire to each light and outlet. Typical lighting circuits would be protected by 15 amp breaker and a circuit with general purpose receptacles would have a 20 amp breaker. A typical lighting circuit might have 10 to 12 fixtures and receptacle circuit might have 8 outlets. If you don't know how to size a circuit get an electrician.

To meet the requirements of the electrical code you have to know the total wattage of the lights that you are going to connect to the 15 amp circuit.

You have to do the math, A 60 watt incandescent draws about 1/2 amp. A 100 W bulb .83 amps. Using Watts = Current x Voltage you can calculate how many.

No more than 13 maximum on a 20 amp circuit.

If the 20 amp circuit is a dedicated light circuit with no outlets or any other lights on the circuit you can install up to 1920 watts of lighting. Using 60 watt track lights you could install up to 32 track lights. If there are other lights on the circuit deduct those.

Should be fine if that is all that is on the breaker.

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.

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.

Install not more that 10 on a 15 amp circuit. You can install 12 if you install a 20 amp circuit.
