how many lights can you put on a 20amp circuit according to the national electrical code?

Question

on a120v 20amp circuit for lighting how many dervices can you have according to nec?

Answer 1

1920 watts maximum. You must use the maximum wattage rating of the fixture, not the bulb. For example, you can have six light fixtures rated at 100 watts maximum, and you can put 40 watt bulbs in them. For circuit calculations, you would figure these fixtures at 600 watts, not 240 watts.

Answer 2

the quick answer is definite, that's against the electrical powered code for a particularly straight forward reason. the code demands lighting fixtures circuits to be break free receptacle circuits so in case you blow the lighting fixtures circuit you are able to plug in a lamp and have easy to repair it. in case you blow the receptacle circuit you nevertheless have easy to repair it. at the same time as that's no longer inevitably a code requirement, lots of the extra effective domicile builders place the refrigerator, the microwave, and the dishwasher on separate circuits. as properly there must be 2 different circuits so which you will toast bagels and make espresso on an identical time.

Answer 3

Check your device to see how many amps each one use. If for example (one) light fixture uses 2.5 amps then you can use approx. 6 fixtures. You only want to use about 75-80 % of the 20 amp circuit, which will be about 15 amps .

Answer 4

According to Ohm's Law you should max out at 2400 watts. So if you are hooking up 100 watt flood lights, you would be able to set up 24 can lights.

Watts / Volts = Amps

Answer 5

4 120volt fixtures based on no more cunsumption then 60watt bulbs
