Since our luminaires operate on single phase, you can take advantage of a 3-phase supply using either one or two legs of the supply to provide either a single-phase line to neutral connection or a single-phase line to line connection. The image below helps to demonstrate how you can use a single-phase power supply through a 3-phase power supply to power your luminaires configured using a line-to-neutral voltage and a line-to-line voltage.
What is the importance of a stable power source and what are the detrimental results of brown outs, black outs, etc? A brown out is a low voltage condition when the voltage drops. It is important to consider having your power monitored in your facility. Monitoring your power quality and voltage variation allows corrective measures to be taken to improve the power quality.
Black outs are when power is turned off then on again, either momentarily or for prolonged periods of time. This could potentially be an issue. Re-striking HID lamps more than two times a day can also be detrimental to the driver.
If blackouts are a frequent occurrence at your facility, consider contacting your utility to resolve the issue or consider installing an uninterrupted power supply [UPS] or generator system. Are there any specific wiring instructions for LEDs? LED luminaires can be wired in the same way as our traditional HID luminaires, based on the Voltage required by the luminaire i. Some LED luminaires can accommodate multiple voltages, whereas others are voltage specific. The voltage range will be noted on the product label.
LED Luminaires that have dimming capability may require separate control wires in order to control the output of the luminaire. Inrush current is one of many characteristics that an Electrical Engineer will take into account when designing an electrical installation. I can't seem to get a accurate answer on what the difference is. For example:Today I opened a v plug it had three power feeders but no neutral. I ran v for my lights which carry a neutral. My problem is that i have done this for 2 years and for my first year i was terrified to ask questions, which held me back.
If you can help please do so. As you see I am very confused on the differences. George Stolz Moderator Staff member. Here are common types of voltages. The second number red is the voltage from hot - to - hot on the different phases. Some loads use all three phases, and no neutral. Some use a hot and a neutral, it depends on the load.

Geoff, don't be afraid to ask questions. How else can you learn? This site is a great resourse. Also, you can go to the public library and see what books they have-I did this a lot when I was new to the trade. The beginning years can be very exciting but also very confusing.
Don't get discouraged though your in a great place on this forum. Your sure to learn something here. It will take time to fully grasp the fundamentals, I would recommend trade school, apprenticeship, self study and this forum.
Mike Holt offers many valuable tools to get you started. George, Is there any where in the prints that should tell the load and what to run.
Phase refers to the method of delivery of the power load. Trying to make a single-phase tool or appliance work in a three-phase system can be a shocking experience, literally! Single-phase distribution is used when loads are mostly lighting and heating, with few large electric motors. To boost to you need a 32 volt boost. This is a common need so transformers are available for V primary and a 32 volt secondary. Wired in open delta boost as in the diagram, you can get V out of V cost effectively.
Simply put, the volt supply is a single phase of a 3 phase volt supply. This allows more light fixtures on a given circuit. It is dangerous.
