I had to drill one hole in the light fixture to mount the new ballast. High-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, or red-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a.

Installation Instructions When using this lighting device, basic safety precautions should always be followed, including the Wiring: Refer to the wiring diagrams page for the appropriate wiring of lamp(s) and ballast. Install in unswitched AC power source of either 120 or 277 volts. Select the proper voltage lead and cap the unused. Fluorescent lamps use a ballast which transforms line voltage to a voltage to start up and operate the lamp(s). Newer fluorescent ballasts are usually rated for both 120 volts and 277 volts. Some are rated for only 120 volts, others for only 277 volts (used in commercial environments)..

In a 480 volt three phase system 277 volts is the star point voltage. It can be used for a 277 voltage supply unless the ballast for this type of lighting is multi tapped. A multi tapped ballast on the other hand can be connected to the following voltages, 120, 208, 240, 277, 347, 480 and 600 volts.. 3 Way Switch Wiring Diagrams Do it yourself help img source : do-it-yourself-help.com. diagram 3 way switch wel e to the 3033 2 section of the leviton electrical and electronic products web site 30 amp 120 277 volt toggle 3 way ac.

Will a 120v-277v LED Driver Work on a 208v Line? In this case, the answer is yes. Just like fluorescent ballasts marked 120v-277v, an LED driver marked 120v-277v will self-adjust to the voltage of the power supply being supplied, assuming the voltage falls in the described range..
