I have a job to connect an irrigation system in a rural area. Electrical discharge lighting is designed to run on 277-volt wiring. Reference Information John Hauck; 2009 Charles Reese et al.

There are cord sets on the pump control box, and also the irrigation control that plug into the gen set. Replace the wiring box cover. After you have made sure that the current demanded by your single phase device can be supplied by the available 3-phase service, it is vital that you make sure you install the correct size of circuit breaker voltage and ampacity and branch circuit wiring having the correct wire size to carry the current load drawn by the single phase device, together with the correct types and sizes of socket outlets. But individual lines are, according to the relevant national electrical standards, including colours e. A rotary phase converter and a transformer would likely be less money and more readily available. L2 should be rewired in white for this system.

All these details are specified in your country's national electrical codes or regulations. Further note For mains power any 1-phase service is usually obtained by using just one phase of a 3-phase service that comes in overhead or underground cables from the generating station. Not big deal usually, just something to be sure of. The voltage of the line conductors are at 180 degrees with respect to the neutral conductor. Add the Engineering ToolBox extension to your SketchUp from the Sketchup Extension Warehouse! The truly 'open' ones are still available, just not as commonly stocked. Sometimes aluminum is used but it's costly too. Technically all are, but some do not allow it, because they have built-in phase loss protection that cannot be defeated.

I've never seen a single phase 480v service. I took a 'screenshot' of your post already 'enhanced' by your camera , smacked the lines onto it with an 'Inkscape' virtual felt-tip marker. Before you do any work yourself, on electrical circuits, equipment or appliances, always use a test meter to ensure the circuit is, in fact, de-energized. So I think I am still missing something. I have never heard of 480 single phase, that is what these light were hooked up as originally.

The nominal system supply voltages listed below can vary by ±10% or more. A 3 phase 480 volt feeder is provided and the load is balanced accordingly. It will be great to see the transformer gurus posts. Copper is the most commonly used electrical conductor, and it's expensive. It is used in business where you're not running a lot of heavy motorized equipment. Cut a piece of cable to run from the switch to the transformer and strip 6 inches of sheathing from each end with the cable knife.

Input Phase Angle and number of transformers needed. The grounded conductor L2 was not phased white either, but I think it should be. The farmer believes that even single phase power with the extra hardware will be preferable to his current routine, and at lower costs. In that case, a single-phase 480 volt line-to-line control transformer is connected across any two phases of the feeder properly fused, etc and steps it down to the 120 volts. You currently have 0 posts. The change in the number of phases is done by a converter but oftentimes, they are described as transformers.

At Agile Magnetics, we have been fabricating custom transformers for more than 20 years; our team of engineers is prepared to design, develop, and manufacture three phase transformers for virtually any application. In both cases the higher voltage allows the use of standard motors whilst saving on cable costs and losses. I have three phases and a neutral available in each light standard pole. I've never run into anything like that, and I'd be really leery of it. If the site owner requires it, it is usually possible to pay the power company to provide a 3-phase service into a house or any other type of property - such as an engineering workshop, vehicle repair garage, etc. Make sure you have that much available in your 240V 1 phase service. The utility company can provide a 480 volt, single phase service from a single phase transformer, usually with a three wire service.

I don't need theory here, I need the numbers. Plus there are other, mostly safety issues, that he probably isn't aware of. This single phase 480 thing is fairly common at least here. If the transformer has a center tap it has to be grounded. Insert the end of a colored wire into a load terminal and tighten the terminal. You may have to use different terminal combinations based on the voltage level at your location.

Don't know if they are willing to have 2 transformers sitting out there, when one would normally do. It's probably a toss up by way of cost. Such a system should be able to start with just about any voltage, and make its own output at whatever level it chooses. In an emergency, you gotta do what you gotta do. Always use proper safety precaution and reference reliable outside sources before attempting any construction or remodeling task! Used in older manufacturing facilities with mostly three-phase motor loads and some 120 volt single-phase lighting and plug loads. If so we invite you to join our community and see what it has to offer.

As an aside, this transformer, being an enclosed potted type is not really typical of what would be used in a machine tool cabinet. Phase B, the high or wild leg, is not used as the voltage to neutral is 208 volt. They won't run 3 phase without costing a fortune, however. I'll try to get some pix of that control box next time I'm out there. I don't think there is anything wrong with this other than the bond should be on the line side of the disconnect. You will need a 277 volt ballast for the type of lighting you are using; being it be Metal halide lamp, high-pressure Mercury Lamp,or high-pressure sodium. But anyhow, single phase in my little world can be 480 line to line and 480 line to ground.
