Photocells are designed to work at night when it gets dark and turn off in the morning when it gets lighter. If the photocell is on during the day then it is not working the way it was designed to. Time to get a new one.

Yes, you can wire a photocell to work at night instead of during the day by reversing the connections. Typically, photocells are wired so that they activate when there is less light, which is during the night. By reversing the wiring, you can achieve the desired effect of the photocell turning on at night instead of during the day.

How do you replace a photocell on your outdoor light post?
# Turn off the power to the lamppost circuit at the breaker box. # Unscrew the mounting screws holding the lamp in place, and pull the lamp fixture from the post. Remove the wire nuts, and use the circuit tester to be sure the power is off. # Disconnect the wires to the fixture and the photocell. # Disconnect the locking nuts that hold the existing photocell on the post, and remove the photocell. If your lamp doesn't have a photocell, you'll need to drill an access hole in the post to install one. # Install the adhesive foam ring (provided with the photocell) around the mounting hole. # Run a bead of silicone sealant around the photocell where it will press against the interior of the lamppost. # Push the sensor through the mounting hole, and secure it with a locking nut. # Add silicone sealant inside the lamp fixture at any point where moisture might leak through to the photocell. # Connect the white wires from the power supply, lamp, and photocell together. Secure the connection with a wire nut. Connect the black photocell wire to the black power supply wire in the same manner. Connect the black lamp fixture wire to the red photocell wire and secure the connection with a wire nut. # Reainstall the fixture on the lamppost.
Can you use 10-3 wire instead of 10-2 wire for basic wiring?
Yes, you can use 10-3 wire instead of 10-2 wire for basic wiring. The extra conductor in the 10-3 wire is typically used for grounding or carrying an additional circuit, providing more flexibility for future electrical needs. Just make sure to properly connect and terminate the wires according to the electrical code requirements.
What will happen if you get the main power from two live wires instead of a live wire and a neutral wire?
If you connect the main power from two live wires instead of a live wire and a neutral wire, it can lead to a short circuit in the electrical system. This can cause damage to your appliances, risk of electric shock, and could potentially start a fire. It is important to always connect electrical wires properly to ensure safety.
Why would you use a braided hose as opposes to a traditional wire covering?
An individual would use a braided hose instead of a traditional wire covering if the wires being covered needed more protection. The braided hose is stronger than a wire covering.
What is the wire coming out of the electric meter?
The wire coming out of the electric meter is usually the service entrance wire, which connects the meter to the main electrical panel in a building. It is responsible for delivering electricity from the utility company to the building's electrical system.

Why does a photocell switch have a neutral wire?
The neutral is needed for the internal sensing electronics inside of the photo cell switch.
When wiring up a photocell where do the leads get connected?
Black Wire from photocel to hot wire(black) coming in red wire to light fixtures black wire. White wire to neutral wires all light and power source white.
How is photocell connected to lamps as a switch?
The photocell would typically control a relay. The power to the lamp would go to one pole of the relay and the lamp to the other. The common wire and ground would go directly to the lamp. The relay would be normally open and would close when the light energy on the photocell decreased to an amount that would trigger a circuit to close the relay.
What does illumination wire mean on car stereo?
The illumination wire on a car stereo is meant for the brightness on the display. It is used to adjust the brightness of the display for seeing it during night hours.
Can you use a normal wire instead of a fused wire?
yes but fused wire is safer.
Can you use regular electrical wire instead of speaker wire?
Yes.
How do you stay safe during the right hand rule?
If you mean the one I think you mean, one way would be to not actually grasp the wire, but to simply look at it and instead pretend to grasp an imaginary wire parallel to it.
Can you use copper wire instead of eureka wire in finding its resistivity?
Yes, you can use copper wire instead of eureka wire to determine resistivity by measuring its resistance, length, and cross-sectional area. However, keep in mind that the resistivity values for copper will be different from eureka wire, so you will need to account for that difference in your calculations.
How do you turn off the lights at night on a 1998 camaro without turning off the engine?
you can turn them off by disabling the automatic lights which is done by cutting the wire should be a grey wire on the back of the switch itself but i'd get a diagram to find out which color wire is the right one instead of cutting the wire you can you can pull the emergency brake one click and light up the brake light in the cluster the lights will turn off.
