Christmas Light Energy Calculators

3. How many watts can I use per circuit*?

*Please consult a licensed electrician before you begin any lighting projects. You can find out how many amps your circuit(s) are rated for by looking at the number on your circuit breaker. Most circuits are rated for either 15 or 20 amps. The above calculator assumes 80% of the total capacity for safety. It is also important to know how many outlets are on one circuit. You can determine this by making note of which outlets stop functioning when you switch a circuit off.

4. How many watts are my light strings*?

*The packaging your lights came in should have either the total watts of the string or the number of bulbs and watts per bulb.

5. How many strings can I put on one circuit*?

*This tool provides you with the maximum number of light strings you should put on one circuit. It does not tell you how many light strings you can connect together. Generally you should not connect more than three 50' incandescent strings end to end. You can connect a larger number of LED Christmas lights together since they use 90% less power. Please see the packaging on your LED lights for more information.

6. How many bulbs can I put on one circuit?

*The number of watts per bulb should be found on the packaging your lights came in.

7. How many amps does each light string/item require*?

*Be sure your light strings and extension cords are rated for sufficient amperage.
