You can add as many light fixtures as you want to the existing switching setup, provided that doing so does not cause you to overload your circuit. To be safe, identify which fixtures and receptacles are on that circuit, and make sure the total connected wattage is no greater than 1440 watts (for a 15A breaker) or 1920 watts (for a 20A breaker). These values incorporate a safety factor by only allowing the circuit to carry 80 percent of the circuit breaker's value. If the total connected wattage is (or will be, by adding the new fixture) over that limit, you'll need to call an electrician to get another circuit and split up your load.

Yes. Connect the two lamps in parallel. White to white, black to black and bare wire to bare wire.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

How do you hook up a light and switch from an existing light?

Add a light to switch from a different circuitI think here your concern is that you don't want change the performance of the circuit to which you add the light.so you have to use a relay or a solid state relay to the circuit and a separate power supply to the light in compliance with all the safety rules.

How do you hook up one light to one switch in a basement lighting system that has all 10 lights connected to one switch?

If you have good access to the wiring this is relatively easy to do. Each of the 10 lights is connected to another in parallel in a "daisy chain" fashion. Light 1 is connected to the switch, light 2 is connected to light 1, light 3 is connected to light 2 and so forth. Let's say it is light 5 that you wish to switch separately. You can first install the new switch by either adding a new box or modifying old switch box. There are two gang switches that will fit the form factor of a single switch. TURN OFF THE POWER TO SWITCH BOX. Using the same supply input at original switch, add a new black wire to the wire nut for input to original switch and connect this to the input of new switch. Then run a new wire to light 5 and connect black wire to the output of new switch. Connect all the white wires together in switch box and separately connect all bare wires together in switch box. Now at light 5 undo the black and white wire coming from the fixture, and reconnect the wire nuts so that there is a direct connection between light 4 and light 6. Do the same for the ground if present (bare wire). You now have the fixture wires hanging free. Now connect the black wire from new switch to the fixture black wire and white to white and you are done.


You have just replaced your ceiling light and when you turned the power back on the light stays on even when you turn off the switch?

Re open the switch junction box after turning the power back off. If you can locate the wire that bring the voltage to the box make sure that this wire goes to the top of the switch. If it is tied into more black wires this could be receptacle circuits that are on all of the time. If this is the case, from this group add a pigtail from this group to the top of the switch. from the bottom of the switch find the wire that is going to the light. It is probably in the group that is tied together. Once found terminate this wire to the bottom of the switch. Put the breaker back on and try the switch.


How can you wire and control 3 lights from 1 switch?

This is simple. First the wire coming from the power supply go to the switch. Then it goes to the first , the second and the third light. Since the switch comes first all three light will be controlled by that one switch.

How do you add another porch light to an existing switch?

To add another porch light to an existing switch, you can run a new electrical wire from the existing light fixture to the new porch light location. Connect the new wire to the new light fixture, ensuring all connections are secure and following proper electrical wiring guidelines. Test the new porch light to ensure it operates correctly from the existing switch.

How do you add a light switch to a ceiling fan that doesnt have a pull switch. i installed a light kit but theres no way to turn off the light. do i drill a hole and add a switch to existing wiring?

It is not recommended to modify the existing wiring to add a switch to a ceiling fan. If the fan does not have a built-in pull switch or a remote control for the light, consider using a wall-mounted smart switch or a plug-in remote control module to control the light. Follow the manufacturer's instructions for installation and ensure the ceiling fan's electrical wiring is compatible with the selected control option.


I have a light that turns on the basement light. I'd like to change that light switch to add a second light on the stairs that will operate separately from the basement light. What do I do?

Tie into the line side (always hot) of the first switch. Run 12-3 to the second switch and then tie the load side of the second switch to your second light. Assure you have all the proper hardware and supports. Turn off all power prior to working on it cause electricity is dangerous. If you are close to your panel its always safest to run a new circuit since you have a limit on how many things can be on one circuit based on your wire size.

How do you wire a pull switch on a hard wire ceiling light that has no switch?

Two options. Change the fixture to a keyed pull-chain, or add a pull-chain adapter to the existing fixture. Both available from Home Depot and others for about $3.


Is it difficult to add a second sink to a bathroom?

It is not excessively difficult to add a second sink. Make sure that there is enough room for the second sink. If you install the second sink next to the existing one, installing T-fittings to existing plumbing is a good idea. anonymous@oola.com


How do you wire a new light with an on off switch using wires coming from another light?

You can wire the new light by connecting the wires from the existing light fixture to the new light fixture. You would connect the hot wire (typically black) to the hot terminal on the new fixture, the neutral wire (typically white) to the neutral terminal, and the ground wire (typically green or bare copper) to the ground terminal. You can then install the on/off switch in the circuit to control the power to both lights.

How do you add a light to a double switch?

The switch you are referring to is called a three way switch operating one or a string of devices from two separate locations. You have to either parallel it at the existing light or find out which end the switch leg and associated neutral is on. Sometimes the electrician will feed the fixture with the neutral and use travellers between switches with 3 wire circuits so you first need to know how it has been wired. It is legal to feed the switches and lamps from any of the locations. Unless you are tapping into the light fixture itself, I would have a professional look at it.


How do you turn off the interior lights with the doors off a jeep?

I bought what is called an "Add A Circuit" fuse link. This thing has two slots for 10 amp fuses and plugs into the "Door Sw Defeat" fuse slot. It also has a wire coming off it to add another line to it. What I did was pull the 10 amp fuse out, plugged in the Add A Circuit and plugged the fuse into the second opening of the new dual fuse holder. Then I installed a toggle switch under the dash near accessible only when the glove box is open. From the toggle switch, I connected a ground wire to it, grounded that to an existing metal screw, and the other wire connected to the wire coming from the dual fuse holder. Flipped the switch and the light turns off. The total cost was, $1.19 for the toggle switch and about 5 bucks for the Add A Circuit connector. Piece of cake! Good luck!
