So, my question, What is the transformer for? I don't see a ground wire, so how do you ground it? Each leg pedal provides power pedal pressure at a unique angle pedal angle to the center shaft. I want to know how to wire up the cobra head light fixture and my voltage coming from my warehouse is 208volts. These are technically more accurate because they refer to the neutral. So my conclusion after thinking it out was to actually wire the ballast common tap to the red and the 240 volt labeled tap to the black. Not all ignitors or starters are capable of remote operation.
But then I got to thinking, how would that complete the circuit? Yeah, I guess that one went right over my head. However, no offense meant here to anyone, but about the last place I want info from on hooking up electronic equipment to high voltages is from a bunch of stoners on an herb forum. Look at the wiring diagram on the ballast as you posted. In this case, the answer is yes. . That usually occurs in a cable that also carries the White neutral line and, once again, a bare Ground line.
And the voltage between the two phases would be then 207. Ballast installations and groundings should be made in accordance with all applicable government codes and regulations where required. Since both com wires are labeled the same, does it matter which one goes to the lamp and which one goes to the wall socket? Some of the lights work just fine this way but the others never light fully and then go out. But anyhow, no, I will not be growing anything with these light unless dust bunnies and cobwebs count! So, my snag is this: The Ballast has the 5 wires, 4 taps and the common. You will need to use a special '2 pole' switch, not a normal light switch.
They are convertible voltage ballasts. Thanks and like your diagrams a lot. For example, 120v-277v will operate on any voltage between 120v and 240v. This ballast has Taps for 277, 240, 208 and 120. Because of 3 sine waves moving 120 degrees out of phase? If you don't have a neutral connection, then the only way you'll get it working is to do as you suggest.
A quad tap ballast would be marked 120v, 208v, 240v, 277v and would have to be set up for the correct line voltage. I have hooked this thing up every way I could think of and it always dose the same thing. A 'split-phase' supply is cheaper, as it requires only 2 high-voltage conductors instead of 3 and a cheaper transformer. Voltages 115v between any one of the three phase lines and the neutral wire can be used for power. Well, seeing as how 2 120's make up a 240, I was thinking I would hook red up to the 240 labeled wire and the black to the 120 volt labled tap.
This way, when the switch if 'off', even though the neutral remains connected, there is minimal risk of injury as neutral is of low voltage. It has exactly the same wires as the diagram for the probe start metal halide ballast above. You need to make sure the wiring is clearly labelled. The neutral wire connects the single phase equipment to the transformer. But there are some issues here: 1. What size wire is needed? It would not work on voltage between 241 volts and 276 volts.
The ballast instructions recommend hooking it up between neutral and 1 phase. I take it the wire labeled 120v goes to the black wire from the wall socket? If it is high pressure sodium, it is supposed to do that when the bulb reaches the end of it's life and needs to be replaced. All of the leads are the same color yellow with the voltage written on the wire. Each leg phase provides power phase voltage at a unique angle phase angle to the center neutral. If you look at the wire you are connecting your line voltage to, it goes into the fixture, and it is connected to a wire nut.
If he showed up with that employed a 120v-277v driver, he would be able to install the bollard lights on any voltage between 120v and 277v. The use of split phase as opposed to single phase reduces voltage drop, so allows higher load handling than a conventional single phase supply. . And if you want to see more images more we recommend the gallery below, you can see the picture as a reference design from your Single Phase 208 Wiring Diagram. As soon as I plug in the photo eye the unit will come on in about 3 min. The bare line still must connect to the light fixture chassis Ground terminal. The ballast data tables in our catalog indicate the page number and reference letter corresponding to the correct diagram for each ballast product.
About 10 to 12 ft away. To view a larger image of the diagram, click on the thumbnail. Almost always, the ballast wiring diagram is printed on a sticker on the ballast core. For instance, the other day, another electrical contractor called up specifically looking for with a 120v-277v driver because he had no idea what voltage was being used. They use the starter as a run capacitor. Normally, you will connect neutral, and a put a switch in the hot wire, but leave neutral permanently connected.
A ground connection must be made to all ballasts to avoid shock hazard, personal injury or damage to the luminaire or installation. Anyhow, I've lurked here a while and think the fine people around here could help verify how to wire this ballast up or if I'm way off base and am about to zap myself. If you look at that ballast wire, it probably says 277V on it. Would the voltage between 2 phases not be square root from 3 times 120V? Single Phase 208 Wiring Diagram Single Phase 208 Wiring Diagram On this website we recommend many designs about Single Phase 208 Wiring Diagram that we have collected from various sites of Wellread Wiring Diagrams Collection, and of course what we recommend is the most excellent of design for Single Phase 208 Wiring Diagram. I also have 480 and out of curiosity how would I wire that one to with a photocell. I like the bicycle analogy.
