Installing a brand new light fixture is an ideal method to transform the look of a room from dull to sparkling one. Catalogs and showrooms for lighting have many different fixtures that are sure to entice you. Even though the array of components included in some fixtures can be intimidating but these electrical wiring connections can be straightforward enough for anyone who is just starting out.

However, poor installation practices could cause a fatal explosion or even fire. We’ll assist you to select a fixture that can be safe to install on the electrical box, and provide you with the most effective ways to test a ground as well as connecting the wires. We’ve also included images of the two most popular mounting systems to help understand all the small pieces 滅蚊燈

The temperatures of your existing wires will determine what kind of fixture you can put in. Before shopping, you should read “Remove the old fixture and inspect the wiring,” below. Examine the wires to make sure the power is turned off. Use the non-contact voltage tester close to each wire to ensure the power source to all wires in the box has been turned off (make sure that the light switch is on). If the tester light is on go out, shut off the circuit breakers or loosen the fuses each interval until the tester light turns off. Remove the wires from the fixture. Other wires remain in an electrical box.

It’s hard to believe but a majority of the fixtures sold in stores and showrooms for lighting aren’t safe to install in homes that were wired prior to 1985. They are marked with a warning label that states “For supply connections, use wire rated for at least 90 degrees C.” The reason for this is quite simple The fixtures with this warning generate enough heat that they can damage the insulation of older wires, causing the risk of fire. Wires made after 1985 must be protected by a covering that can stand up to the higher temperature.

If you are certain that your wiring was put in place prior to 1985, you shouldn’t install fixtures that require supply wires of 90-degree rating. To determine if you have 90-degree-rated supply wiring examine the cable’s jacket or insulation. If you’re using plastic sheathed cables (often known as Romex) check for the letters NM – B or UF-B that are printed in the plastic. If the wiring is fed via conduit, check the insulation of the wire for letters THHN or TWN-2. If you’re not sure then you should consult an electrician or opt for the fixture that’s not labeled with a temperature of the supply wire requirements. If you opt for a large lamp (the one we picked came in at 25lbs. ) Check the electrical box to make sure it is able to support the weight. It is recommended to check the National Electrical Code (NEC) permits hanging up to 50lbs. from any electrical device that is threaded to accept no. 8-32 machine screws that are used to join to the crossbar (see “Mounting with Screws and Cap Nuts” and “Mounting with a Threaded Pipe” in the Additional Information section below). This covers almost every kind that ceiling boxes are available.

To be practical ensure that you have your electric box securely attached to a solid frame before you install an upcoming light fixture over it. If the light fixture weighs over 50 pounds. It should be supported without an electrical outlet. A simple solution is to put in an appliance called a fan brace (available from home centers as well as hardware stores) which is made to be put in place without drilling any holes into your ceiling. Look over the label to be sure that the box is built to hold greater than 35 lbs.
