It has a 4 wire connector to my car but one of the wires on the trailer connector was worn out and probably not working. So I got a new 4 prong connector for the trailer but that 4 wire adapter goes to 6 wires on the trailer. This particular trailer has what I call “surround” lights in addition to turn signals and brake lights. So, one wire is “common” and I’ve used alligator clips to hook up and test what the other 5 wires do. One of them does nothing and I think it’s because one of the connections in the back are not connected and today I’m going to try and take off the back panel to get to the lights the light fixture itself is riveted on. So, what should each of the wires do and how should I hook them up to my 4 wire system? Also the brake and turn signals are the same bulb just different filaments. I call them the “small filament” and the “big filament” even though they are the same size. When the parking lights are on, is that the “small filament” on and then the brake and turn signal activate the “big filament”?
Connecting light fixture: two white wires Where is the black
Skaperen It’s not the DC that loses alot It would be the same for AC at the same voltage. When the voltage is lower, the current has to be higher to get the same power across.
Connect the wires. Follow the manufacturer’s instructions for matching the wires on the new fixture to the wires installed in your home. Typically, the black wires connect to each other, and the white wires connect to each other.
Grounding Wall Outlets and Light Switches: What do I do with the ground wire for a porcelain ceiling lamp holder when there is no place to attach it? I understand that on a porcelain ceiling lamp holder cooper wiring devices you do not need a ground wire and there is no place for it. I am not wiring to anything that is metal, and the devices are porcelain and plastic blue boxes. What do I do with the ground wire that is in the Romex electrical cable?
Do I just trash it or should I attach it to the screws that are attaching the porcelain fixture to the blue round box? This electrical wiring question came from:
How to wire up a Simple Fluorescent Light
Wire manufacturers supply wire in a wide variety of colors, and it is up to the electrician to use the correct wire color in home wiring. The purpose of a red wire for wiring a light fixture varies, but is easily determined in most cases. Green is reserved for ground, and may have yellow stripes. The ground wire often is bare copper. White wires are reserved for the grounded conductor — often referred to as neutral.
I bought some cool LED light fixtures. However didn’t know they were V There are 4 wires coming out of 2 boxes all are red. box 1: LED Transformer Transfor mer PCS is marked on the box. DC black + and White – wirers connect to light fixture.
Email Shares Last week I described how an outlet should be wired for switch control when the voltage enters the circuit at the outlet. This setup is how our master bedroom was wired before I installed an overhead ceiling fan. As promised, I detail below how to modify this wiring setup with minimal effort so that the switch can instead control an overhead fixture. The white neutral wire from this Romex is connected directly to the silver terminals on the receptacle E , and the black hot wire is connected to the white wire running to the switch B.
The white and black wires from this Romex are connected to the switch C. The black wire at the switch is now switched hot which is run back to the receptacle and connected to the gold terminal D. Notice that in this diagram, the neutral wire never leaves the receptacle box. Voltage exits the receptacle box on the white wire to the switch, and then returns as switched power on the black wire, both in the same Romex cable.
4 sets of wire from ceiling for one light
Can two motion detectors be used for outdoor flood lights? I would like to control my outdoor flood lights with more than one motion detector so the light can be triggered to come on if there is movement detected in different directions. If this can be done using standard motion detectors, do both red wires from the motion sensor tie to each other. Then the two black wires from the motion sensor will tie to the hot wire from the main power. This electrical wiring question came from:
Two-wire cable runs from the last switch to the light fixture and the common on that switch connects to the hot terminal on the light. 4 Way Switch Wiring with Light First This diagram illustrates wiring for a 4 way circuit with the electrical source at the light fixture and the switches coming after.

Different wiring arrangements are included to allow for either the light or the switch to come first in the circuit.

BillR85 1 year ago Reply The light switch should always remain in the on position for the photocell to operate automatically. Turn the light switch off first to make sure the lights do in fact turn off to isolate the problem to the wiring at the photocell or the photocell itself. If the lights remain on with the switch off Highly doubtful you have something messed up. I will assume the lights do go out when the switch is off.
As long as you don’t feel a shock when you touch the light and anything else metal, you’re fine. If you do feel a low-voltage “buzz” when you touch the fixture and another plugged in item, try reversing** the fixture plug to eliminate.
Tester k Your diagram doesn’t make it clear that the live wire going to the fixture [i. Edison sockets IIRC are supposed to have hot at the bottom point and neutral in the side. To test this, get a meter. Unhook the fixture and label the blacks, B1 and B2. This would be the line to the breaker. The other pair should show nothing – with the switch both on and off.

Can’t find a solution to your problem? Post a question in our Forums. The dimmer switch that I have has only 2 wires and the switch has 3? You can use a three-way, rotary, push-on dimmer switch. Leviton makes them and they work fine for three-way switch applications. I’m assuming this is a loop. I want to replace this with a combo switch outlet that will have the outlet on at all times and the switch operating it’s current load,a light. Behind the wall,there is a switch that’s on the same breaker.
Can I piggy back the neutral wire from this switch to my new combo? I am afraid you can’t do what you are thinking. Then you can use the white as the neutral for the outlet and the red wire for the return to the light as the switch power lead. If you can pull the box out of the wall and run a 3 wire cable to the outlet from the fixture, you can wire it that way.
