How do you wire a 220 volts light?
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
What do you need to wire in a mercury vapor bulb?
The same procedure is used to wire a mercury vapour fixture as it is a normal home fixture. First the voltage source is needed and has to match the voltage that is on the nameplate of the mercury vapour fixture. The amperage of the fixture has to be taken into consideration, also taken from the fixtures nameplate. Once the amperage is known then the decision is whether one or more fixtures will be placed on the same circuit. When the total amperage is decided on, it will be that amperage that decides what size conductors will be used and what size breaker will be used to protect the circuit. Next decision is how you want to control the fixture. There are two methods depending on where the fixture will be placed. If it is outside then a photo cell with a bypass switch ahead of the cell is the most common configuration. If the fixture is an indoor type then just a wall switch will be used to control the fixture.
What is a poor conductor of electricity and is used to coat wires?
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
You have an outside light that won't work but switch has power?
First and foremost make sure the light bulb is a good one. Try it in another fixture to make sure, even if it just came out of the box it was packed in. If you have checked the switch for power then you must have a tester. The power coming to the switch will most likely be on the top screw. Turn the switch on and see if you have voltage on the bottom screw. Check this voltage from the screws to the ground wire as the neutral will not be accessible in the back of the switch box. If there is voltage to the bottom screw then move on to the light fixture. Remove the outside light fixture and see if you get a voltage reading on the incoming hot (black ) wire. If there is voltage there then you have to see if the lamp holder is making continuity. If you have an ohm meter or a continuity meter remove the lamp fixture from the "hot" wire and the neutral connection and see if you get a reading across the fixtures black and white wire. This has to be tested with the bulb in the fixture. No continuity reading then there is trouble with the socket. Might be time to think about a new fixture.
How do you connect a 3 wire fixture to a 2 wire fixture that are connected to the same switch what do you connect the red wire to?
A three wire fixture most likely is one that has two separate loads within it. An example is a ceiling fan with a light fixture. If the three wire is used to separately switch the two loads you have to make a decision as to which load you want to work with the two wire fixture. Once that decision has been made connect the two wire fixture in parallel with the your selected load on the three wire fixture. On these types of installations the three wire fixture is usually controlled by two separate switches in a two gang box. The red and black wires of the three wire terminates on the bottom of either switch. The white wire is connected to the incoming neutral. The top of the switches are paralleled together with the "hot" feeder from the distribution source.
What happens if someone touches a high voltage wire?
If they are grounded they get an electric shock or electrocuted. If they are not grounded or in simultaneous contact with the neutral wire, nothing. That's why birds can sit on a high voltage wire and survive; they are not grounded.
What do I attach the green wire from the light fixture to?
The green wire on the light fixture is a ground wire. If there is no ground wire in the conduit, the green wire should be attached to the metal box with a screw.
How do you wire a high watt light to a battery?
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
Can 10-2 yellow wire be used to run low voltage lights?
10-2 wire can be used to provide power to low-voltage lignts.
Short distance transmission of power is done at higher voltage or higher current?
High voltage is used to transfer power over long distances ONLY because the gauge of the wire can be smaller. Power transfer is always most efficient at the operating voltage if the size of wire is not an issue.
How do you step down voltage in transformers?
step up or stepdown is done by the ratio of the number of turns in the primary / secondary coil, large number on high voltage side small number on low voltage side. the wire used on the low voltage side would be thicker than the high.
What type of conductors shall be used for wiring on fixture chains?
The type of wire you are looking for is called lamp cord. It comes in different colours usually to match the fixture. Fixtures hanging from chains use a clear insulation so as to blend in with the fixture chain colour. Remember that the smooth wire of the lamp cord connects to the hot wire and the ribbed wire on the lamp cord connects to the neutral wire in the ceiling junction box.
