As an electrical engineering expert, I have a deep understanding of electrical systems and their capacities. When it comes to determining how many lights can be on a 15 amp circuit, it's essential to consider both the electrical code requirements and the specific power requirements of the lights you intend to use.
Firstly, the calculation provided in the reference is a good starting point. For a 20 AMP circuit, you have a total capacity of 2400 watts, and for a 15 AMP circuit, it's 1800 watts. However, as the reference suggests, it's prudent to plan for an 80% load to ensure safety and avoid overloading the circuit. This means you have 1920 watts for a 20 AMP circuit and 1440 watts for a 15 AMP circuit to work with.
When planning the number of lights, you must consider the wattage of each light fixture. For instance, if you are using LED lights, which are typically more energy-efficient, they might consume around 10 watts each. If you are using incandescent bulbs, they could consume more, possibly around 60 watts each or more depending on the bulb type and brightness required.
To calculate the number of lights, you would divide the total available wattage by the wattage of a single light. For LED lights on a 15 AMP circuit, you would have:
\[ \text{Number of LED lights} = \frac{1440 \text{ watts}}{10 \text{ watts/light}} = 144 \]
For incandescent bulbs, the calculation would be:
\[ \text{Number of incandescent bulbs} = \frac{1440 \text{ watts}}{60 \text{ watts/light}} \approx 24 \]
It's important to note that these calculations are theoretical and assume that all the lights are on at the same time, which is not always the case in practical scenarios. Moreover, a circuit isn't solely for lights; it may also power other electrical devices. Therefore, it's crucial to account for the total load, including the lights and any other devices that will be connected to the circuit.
Additionally, local electrical codes must be adhered to, as they dictate the maximum allowable load per circuit and may have specific requirements for the number of lights or types of fixtures allowed. Always consult with a licensed electrician or your local electrical code for the most accurate and safe installation practices.
In summary, the number of lights that can be on a 15 amp circuit depends on the wattage of the lights and the total load you plan to have on the circuit. It's always best to calculate based on the specific fixtures you intend to use and to ensure that the circuit is not overloaded, keeping in mind the safety and efficiency of your electrical system.

For 20 AMP you have 20A*120V or 2400 watts and 15 AMP you have 15A*120V or 1800 watts. Good Electricians will only plan for 80% load so you have 1920 and 1440 watts respectively at your disposal per circuit. Next, find out what's on the circuit. To do this, leave the lights on that you want to connect to.Oct 13, 2014
