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 must have a switch to turn the disposal on and off. If you are asking how to connect because you do not have a switch. Install the switch under the sink just above the door opening. You can buy disposals that turn on and off when you place the lid over the hole. InSinkerator makes one.
the black wire is the hot wire
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 wire a time clock with a contactor with a override switch
White and the ground go to the disposal, black goes through a switch and then to the disposal. All three go through the switch box, the white and ground just pass through on the way to the disposal. Break the black with the switch.
with a standard 1 pole light switch (one switch operating the light) it is black wire to black wire and white to white (non grounded)
Current flows through a wire when a light switch is turned on.
To install a new garbage disposal you will need: a wrench, Philips screwdriver, flat screwdriver, a hose clamp, plumber's putty, and wire nuts. http://plumbing.lifetips.com/cat/64351/garbage-disposer/index.html
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
If you have one wire into your switch box for your light. this is called a switch leg, the dimmer should be wired across the black and white wire wires.
by a parellal current switch.
The switch probably turns the light out when the switch makes connection, then the light is on when there is no connection (like when the wire is not connected.) Reconnect the wire and push the switch to see if the light goes out. The switch is most likely out of adjustment or bad.
You put switch in series with the black supply wire and the black wire to the first light. Then connect black wire of first light to black wire of second light, black wire of second light to third light and so forth. Do the same with the white wires and ground wires.
If the question is, can I wire a switch to an existing light fixture (and I must assume that it's something like a pull-chain light fixture), the answer is yes.If the question is, "how do I wire a switch to an existing light fixture that has no external switch", the answer is, "in series".The attached web site gives simple instructions on how to wire a basic light switch to an existing light.See sources and related links below
Just wire it to a toggle switch. When you need it, just flip the switch.
you don't it is illegal
