The second option allows you to easily disconnect fixtures you no longer want to use but it becomes cumbersome when more than two fixtures are involved. How many led lights on one switch.
Tutorial 3 Way Switches And 4 Way Switches
How many lights on one switch. You can put up to 30 lights based on 50 watt light on a 15 amp breaker. You can put all of them on one switch or use multiple switches. A 6a switch could manage 70ish 20w lamps. This would be a two wire cable black white ground take the black wire and connect it to one screw on the switch and connect the ground wire to a screw inside the electrical switch box mounted to the wall. One cable connects to the previous light the other continues to the next light. A 20a switch could manage 9ish 500w floodlights.
Basically the simplest way to have multiple lights on one switch is to run a power supply wire to the switch first. 50 watt light equals less than 12 amp current flow at 120 volts. If three four or even more lights are required to be switched from a single source the new cable can be extended to as many lights as required. A basic 15a circuit will allow you to connect up to 1400 watts of lighting load. You have to measure the amount of energy being taken by the other devices in the circuit. Here the ceiling rose is shown with two cables both of which connect to line neutral and earth with no loop connection.
To figure out how many lights can be installed on one circuit breaker you have to know the following. Each cfl or led bulb typically gives the same amount of light as a 60 watt incandescent bulb while drawing 10 watts or less which is equivalent to a current draw of 112 amp. Thats more than youd ever install in most rooms. Switch on the light or device in the circuit which you want to measure. So how many lights on a 15 amp circuit that already has so many applications connected to it. That can be one 1400w fixture or fourteen 100w fixtures.
Rating of switch x 240 wattage of lamp. 100w incandescent bulbs are becoming extinct. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a home run configuration. You can put up to 40 lights based on 50 watt light on a 20 amp breaker. That would depend entirely on the rating of the switch and the rating of the lamps.
