Varying degree of lumen output from the connected lights, all below the intended rating of the fixture, and the fact that if one light burns out, the entire … "Thinking there might be a grounding problem because the ground wire was solid core, with a painted green bolt, I worked on the grounding contact to make it better.". What I don't understand is if the GFCI is sensitive to a "leak", why doesn't it trip during the first time the light is turned on. That being said, there's no reason not to attach lots of ballasts in parallel to a single power supply, as long as you're under the rated amperage of the circuit. In some cases where the ground wire has not been attached correctly, the fluorescent lamps may not light up at all, or the lamps will burn dimly, and this will cause the lamps to burn out prematurely. The fixtures were just recently purchased (new) at Lowes. In either case, why wouldn't either cause the breaker to trip while the light is on rather than the next time the switch is turned on? Newer electronic ballasts are instant start (wired in parallel), rapid start (wired in series), programmed start (wired in series-parallel, dimmable and CFL ballasts. Wiring Diagram for Fluorescent Lights New Wiring Diagram for. You will have three wires in each wire nut. "Also removing the bulbs from one of the fixtures, seems to fix the problem - so is the other fixture "bad" - but why does it come on at all?".

When turning on the lights does tip the breaker, it is immediate - ie the lights don't even come on for a second. 404.14 (E) Dimmer Switches. The two ways together create enough current leakage to ground to cause the GFCI to trip, especially with multiple fixtures. SAME STORY as original!!!!!!!!!!!!!!!!! First bulb had a ground, 2nd one did not. Wiring lights in series results in the supply or source voltage being divided up among all the connected lights with the total voltage across the entire circuit being equal to the supply voltage. 7 Things to Know Before Buying and Installing 12V LED Strip Lights 355.2k views; Wiring LEDs Correctly: Series & Parallel Circuits Explained!

A wiring diagram is a type of schematic which makes use of abstract pictorial signs to show all the interconnections of elements in a system. By doing this, you could run a piece of "Romex" straight out the back and straight into the wall. (That is where my idea in the last note came from), First, "(not before - I have checked the breaker to see if it trips when turning the light off after the first "turn-on" & it doesn't).". So, a live/neutral/ground run to light 1. What are your DIY skills? Fluorescent lights require a ground wire from the electrical circuit to be attached to the metal frame of the light fixture, and the grounded metal reflector must be mounted within 1/2 inch of the lamps.

Hopefully this will make it clearer as to what the wires at the ceiling rose are for. These are T5 lights suitable for under counter mounting. Color temperature measurement is in Kelvin (K) and most colors range from 2500 to 6500k.A lower Kelvin figure means the color is warm and tends to be closer to orange.. By contrast, a high Kelvin figure like 4000k means the color is cool and white in appearance. Following the manufacturer’s directions, use an electrical multitester to make certain the power no longer runs to the circuit. Continue to repeat this step for the remainder of your fluorescent fixtures in this series.

The type of insulation we are talking about can melt when it gets hot, and then resolidify when it cools (intentionally), making the insulation work just fine at the startup voltage once cooled. Wiring the lights in this manner is called ''in parallel'' not ''in series.'' She attended Tarrant County College and studied English composition. Parallel or series-parallel wiring method is more reliable instead of series wiring. 1. The circuit has been interrupted, although there is a way to trip a GFCI without a current in the hot leg, it would do it whether the switch was on or not. You can see that there is a Live and a neutral that has come from either the consumer unit or from another light fitting. This in turn trips the GFCI. Determine the length of the circuit cable that will run from the location of … Although the breaker does not say it is a GFCI, it has a "test" button on it which leads me to believe it is. The consumer unit is normally connected to the first lamp, which in turn is connected to the second lamp and so on. Let me help (hopefully) with the logic one more time.
