if light switch is off is there still power

Change the light bulb by twisting it up into the socket, using the same amount of force you used to remove the dead one. This, in turn, causes a low voltage drop to appear to LED driver, and as a result the LED bulb glows weakly. A three-way switch is one that works in conjunction with another three-way switch to power the same light. If you have a wall switch to turn on and off the fireplace, it will still turn it on if the power goes out. This is a poorly worded question. 5. There's two ways to accomplish the switch having power…. Even if your light switch is technically still working, you could have a fire hazard. But there are several reasons why this could happen. I just wanted to show that it does happen. One your bulb has been installed, flip the power switch to turn it back on. Causes of Lost Power After Changing a Light Fixture Ignition pin # 5 color Yellow-- Should have power when run, power to engine. A lighted switch has the light across the contacts.

If the green light goes off and the outlet stops working, it means that the outlet has either tripped or the circuit doesn't have power. They're used to operate devices that consume up to 120 V of power. This kind of negates the point of the SMART light, since you just turns off power to it. There are many factors that come into play that can cause you to still get shocked when performing electrical work even though you have shut off the breaker to the area that you are working on. When you cut off the current, it stops heating the filament, so it cools down fairly rapidly, but there may be enough residual heat for a faint . Faulty Circuit Cable. 2. That way, they're ready at a moment's notice whenever you decide to turn the lights on remotely. If the switch won't turn off the lights, it's probably because you bypassed it somehow. Depends in part on whether the the switch is before the light or after the light. Locate the circuit breaker, make sure it is turned all the way off, then switch it back into the on position. They have two leads and a light the lights up when current is sensed. As I stated I changed the switch, but the light stays on constantly even without being connected to the switch as long as the breaker is on.The box has three set of wires, black/white/ground from the fixture, a black/white/ground, and a black/red/white/ground. You might notice that LED lights tend to stay or at times dim even when the off switch has been toggled. However when I went to test the power, I noticed that there is still power going to the outlets and the light switch. I still don't see why you'd not turn the electricity off. hi guys, i am new here. When I was changing a light bulb in my ceiling pot light fixture, the power switch was turned off, and I touched the base of the lighbulb (the metal part) as I was screwing it in. An electrical short or an accessory that is not functioning properly could cause excessive drain on a battery. This is usually due to the residual current left behind. A drained battery at the time of activating the battery isolation is a valid one. Circuit breakers are usually found in basements or closets, behind an electrical panel door. It is still a common way to wire a switch. Light Up. Power at switch or power at light are very common ways. If the light is red, the GFCI has a problem. This electrical question came from: Jim, a Handyman from Irvine, Ca. Hi there, I had an electrician fitting couple LAP 10w simple floodlights (not PIR) in my shed and a BG 1 way outdoor switch. Probe the wiring with a test light or voltmeter to check for signs of life. Each individual circuit breaker automatically shuts off if there is a problem with the circuit, such as a short circuit, or an overload—where the circuit is overloaded and draws too much power to safely handle. The main circuit breaker, usually located inside the main panel at the top, shuts off all of the electricity to the house. I got zapped. It just depends if the power source is closer to the switch or the light. The problem is when the power comes to the switch, and then from the switch to the light outlet (or lights), and only on a 2-wire cable. I have a strange one I'm replacing a lot of switches & outlets down stairs when I cut the power test the outlets and switches all is good however when I was trying to work the up stairs I turned the breaker off and with test plug it into all the outlets tester showed no power so pulled a cover off standard porcelain light to replace it with a switch I test the wires again before starting . (FTR it's a 2-prong ungrounded outlet) Otherwise, shut off only the breaker that serves the problem circuit—that way, other parts of your house will continue to have lights and power. In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets.Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. To be entirely sure the power to the light is off, switch off the power to the light at the . Incandescent Lighting. When the lamp's switch is in the off position, the LED bulb still emits a very dim light, whereas the halogen ones do not. In the process of testing the . Such a smart lamp would have a normal-looking physical on-off switch, but switching it to the "off" position would send a Wi-Fi, Bluetooth or other wireless signal to the hopefully compatible smart bulb toß un-illuminate it. If the wire is energized when not attached to the circuit breaker then there was two power sources providing power to one circuit. Answer (1 of 19): Which is on and which is off in the I/O switches? Period. In a dire emergency, this is the one to turn off. why do some lights glow when turned off. If the wire is not energized but the terminal of the circuit breaker is energized while the breaker is switched OFF then the circuit breaker is faulty and would require replacing. Try turning the switch you've jumped to the "on" and "off" position. Although the principle of light switch wiring is fairly basic, things can sometimes get confusing when the switch is in the middle of a circuit or it controls more than one light and there are multiple wires in the electrical box. The green light will only come on if the outlet is working properly and it has power. In the above image, there is a solar panel attached to a battery to charge during the day. If either wire at the light fixture is still hot then the switch is wired incorrectly.If one of the wires is still hot at the light fixture with the switch in the off position, then you most likely have the light switch on the neutral wire.Separate the bare ends of the wires so you can safely turn the power back on. then the other light stop working so i thought it might be the switch which i changed and still nothing. Remove the wires from the terminals. The short answer is Yes! Power to the switch and then pass the switched power on to the light.

Before attempting to fix any problems with your light switch or light sockets, remember to turn the breaker off first to avoid electrocuting or burning yourself. Z-wave switches require power to flow through them all the time (this is how they have power to light up their status LED, and listen for z-wave commands), even when the light is off. What you are measuring is the line voltage going across the bulb to neutral. If you find power now, you either have a bad connector or the socket is faulty. That is normal. Now you have. Old dimmer switches just used a variable resistor - the same amout of current flows through the whole circuit, but the resistor causes a voltage drop which decreases the light output of the bulb. i changed the switch and still no power. Another possibility is that the switch or relay for a rear window defogger might get stuck in the "on" position, which would draw power from the battery even after the engine is turned off. This type will not work properly when used for a light switch. This was at the inspection this morning and the home was built in 2000. Weirdly the outlet that I just replaced is now showing power to it as well. Turn the wall switch on and there's normal full power, as would be expected. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as . In this case, you must change the cable from the switch to the light outlet from a 2-wire to a 3-wire cable. If the circuit breaker trips off then there is still a problem with the light fixture wiring which will need to be inspected and repaired. If there is still power to the room, then we know the outlet without power is the issue. What you are measuring is a floating voltage. The best Digital Meters have a very high input capacitance as Jacob pointed out, That is normal. The on/off switch on solar lights allows you to completely turn off the unit when it's not in use. listed the colors that appear to be used in a number of there ignition wiring at the key switch. The light on power button is the same like CapsLock or NumLock lights which you can turn off easily. There is no "used to be" about it. Newer dimmer switches simply turn off the flow of current at certain points in the AC cycle, so overall it does consume less power . I turned the breaker off to that room - confirmed power went off with a lamp plugged into one of the outlets that turned off as well as the overhead light. 90% of the energy they use is given off as heat, and only about 10% results in light. The light bulb is on a circuit with a switched neutral wire, instead of a switched hot wire. receptacle that was tripped and still had power. The ceiling light is then connected to a second ceiling light and that one to a third.
