Nec led driver

Disconnecting LED Drivers. Thread starter mjc Start date Sep 3, Status Not open for further replies. I am installing a Lithonia LED fixture. I noticed the manufacturer did not include a disconnecting means for the driver. This luminaire is a pendant fixture hung below a suspended ceiling fed by a cable that terminates in a box above the ceiling.

The driver is V on the line side. JFletcher Senior Member. Location Williamsburg, VA. See Location Miami Fla. Occupation 60 yr old tool twisting electrician. JFletcher said:.

In indoor locations other than dwellings and associated accessory stru ctures, fluorescent lumin aires that utilize double-ended lamps and contain ballast s that can be serviced in place shall have a disconnecting means either internal or external to each luminaire.

Great answers is a Data Center a commercial or industrial facility? New construction requires a work permit that must be obtained from a local safety or electrical inspector. Some small jobs may not require a permit but it is in your best interest to get a safety inspection to avoid any unintended problems. For example, if you re-wire a kitchen or basement without having it inspected and then try to sell the house, an inspector may ask you to tear the walls down to check the wiring.

Also, if faulty wiring that wasn't inspected starts an electrical fire, your insurance company might challenge the claim. The rough-in inspection consists of checking that all wiring is properly installed before any switches, fixtures, insulation and walls are added. For low-voltage installations, this is when the inspector will specifically check to see if the wiring is Class 2 compliant.

Basically, the skeleton of the installation will be reviewed to see if the correct gauge wire is installed and harnessed correctly, as well as other measures.

Once the rough-in inspection is passed, you can then complete the installation with insulation, walls, switches and fixtures before the final inspection.

When checking low voltage LED lights and systems, the inspector will check to see if the power supplies are accessible and Class 2 compliant. Once the inspector approves that the project meets professional standards, you can begin using your new circuits safely and confidently in compliance.

Wondering what you can do to make sure your project gets approved? Next, we run through all the lighting project components. Power supplies convert the V power into low voltage 12V or 24V power. Power supplies that comply with the Class 2 regulation are always marked or labeled as so. To pass inspection, a junction box must be installed to encapsulate a V AC wire connection to a V DC power converter driver. Junction boxes provide a safe, grounded fireproof enclosure, preventing wire nuts from coming loose and causing a short and possible electrical fire.

This Lo-Pro Junction Box is one example of how to separate high and low voltage wiring within the same enclosure. For large projects such as kitchen remodels, office upgrades or new commercial spaces, a large amount of power is often required.

In this case, you have two options: You can install several 60W drivers, or you can install a high wattage multi-tap driver such as the 12V Watt Class 2 Driver. Dimming interface: Many drivers allow dimming of the connected LEDs and accept control input through an interface.

Phase-control drivers do not; they accept control input from a line-voltage wallbox or other dimmer through power wiring.

When replacing a driver in a luminaire, the new driver should function the same as the original. To ensure this, the new driver should match the same characteristics while also providing a form factor allowing it to fit in the same space within the luminaire.

Mismatching can create performance and safety issues or failure to operate. In some cases, the issue may not be immediately apparent. For example, installing a Class A driver in a residential application could cause TV or radio interference. First, take a photo of the driver label and the LED module being controlled. All information on the driver label should be clearly legible.

Consult the luminaire label and installation instructions for information about the system and driver replacement. It can be relatively straightforward to use a driver from the same manufacturer as a replacement.

Submit the model number and tune programmed current level to the luminaire or driver manufacturer. Most manufacturers provide the programmed current level on the label or a second label. The manufacturer may provide a list of suitable replacement drivers along with their characteristics. Note that programmed tune values typically do not transfer from one manufacturer to the next.

Tuning can be difficult to replicate. If the current is too high or low, the luminaire may appear too bright or dim compared to other luminaires sharing the same space.
