How many LED lights can you put on a 20 amp circuit?

Answer 1

The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. Therefore you can have a load of 1,920 watts on this circuit. Assuming you install 8 watt bulbs you can have 240 on this circuit.

Answer 2

A 20 amp circuit at 120 volts will handle 2,400 watts. But you should never load a circuit over 80%. 20A@120 volts = 2400 watts x 80% = 25 lights of 75 watts each. If each fixture has 2 lights then only install 12.

Answer 3

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.

Answer 4

100

Answer 5

40 lights
