A primary concern when deciding what type of generator is best for your environment should be making certain you get the right electrical configuration. An electrical configuration typically includes the phase, voltage, kW, and hertz that are best for your application. In order to explain how phases and voltage work, it is helpful to understand what a generator set includes.

A generator set also known as a genset is comprised of two primary components - an industrial engine usually diesel, natural gas or propane and a generator end. The engine produces horsepower and RPM, and the end coverts it into electricity. Single-Phase Generators — for smaller single-phase loads, these gensets usually do not go above 40 kW.

How do I connect a direct on line (DOL) starter to a single phase motor?

They are commonly used in residential environments and have a power factor of 1. They are typically used in commercial environments and have a power factor of 0.

For example, a kW 3-phase generator would drop to around 70 kW when converted to single-phase. The load on the engine itself is not affected because it is the generator end essentially kicking into overdrive.

To ensure the voltage configuration is exactly what you need, you should always consult an electrician or electrical contractor. They can evaluate your environment and determine the various loads your facility or operation will need, and will also be able to take into consideration other variables such as the voltage going into the building, maximum amperage, electric motor horsepower output and more.

You can also reference our Power Calculator to run numbers. Many motors will run at a certain kW but have a much higher starting kW requirement. For example, you may need kW and increased amperage at startup even though your average running load is only 90 kW. Electric motor horsepower requirements are also good to evaluate. Certain motors come with a soft starter that helps control the acceleration by applying voltage. Some industrial motors will provide all this information on their data tag.

Most large ships and airplanes use a specialized Hz frequency. To change the utility line power to a different frequency, a frequency converter can sometimes be used but there are additional factors to consider. Most generators can convert but some gensets will not function properly or may require additional parts and customization work.

Consult your generator manufacturer for additional details on this type of situation. While the voltage can be adjusted on most generators, your specific options will always be limited based on the generator end you are working with. The process of changing the voltage itself is a relatively technical electrical procedure that primarily involves adjusting the leads on the generator end.

On most 3-phase gensets, we typically take the 10 or 12 leads in the generator end and reconfigure how those are arranged and connected, adjust their route to the control panel and a few other places - depending on what we are trying to accomplish.

This is where terms like dogleg and double delta or zig zagY-configuration and other various wiring schemes often get referenced.By code, the number of conductors allowed in a box are limited depending on box size and wire gauge.

Calculate total conductors allowed in a box before adding new wiring, etc. Check local regulations for restrictions and permit requirements before beginning electrical work.

This page contains wiring diagrams for a service panel breaker box and circuit breakers including: 15amp, 20amp, 30amp, and 50amp as well as a GFCI breaker and an isolated ground circuit. This diagram illustrates some of the most common circuits found in a typical amp circuit breaker service panel box. The breakers are installed in a panel so that contact is made with one of two hot bus bars running down the middle of the box.

The hot wire for a branch circuit is connected to the breaker by a set screw on the base. The neutral and ground wires for the circuit are connected to a bar along the side of the service panel box. The neutral and grounding bars in the panel may be separate or, in the case of older service panels, the same bar may be used for both purposes.

This wiring diagram illustrates installing a 15 amp circuit breaker for a volt branch circuit. A 15 amp circuit is usually used for wall receptacle outlets and room light fixtures. This diagram illustrates the arrangement for a 20 amp, volt double receptacle circuit with a shared neutral wire.

It may help to take a few minutes to familiarize yourself with all of the tips in the related wikiHow article on "How to Master Do It Yourself Electrical Safety ". Shut off all the individual circuit breakers in the panel and then shut off the main switch that supplies power to the panel.

This is preferable as it is much safer to operate many smaller current devices, one at a time; than to operate a single, large current device just once. When all the smaller circuit breakers are off, the amount of current flowing through the larger 50, or more amp circuit breaker should be zero.

How do I connect a direct on line DOL starter to a single phase motor? Published date: 29 April There are a number of issues: We do not manufacture a complete starter specifically for single phase motors but our 3 phase starters can be wired for single phase applications. Relative to their power output, single phase motors draw much greater current than 3 phase for 2 reasons: 1. Single phase motors are considerably less efficient than 3 phase so losses are greater and current consumption greater still.

This means that typically, single phase motor current will be at least double that of 3 phase motors of similar power output. As the power ratings of our starters are based on VAC 3 phase it becomes necessary to base starter selection on the full load current of the motor and NOT the power rating. It is possible to use one of our reversing starters with single phase motors but it does require extensive rewiring to do so.

This issue is complicated by the fact that there are a number of designs of single phase motors and the method of reversing varies between them. Therefore wiring a reversing starter for single phase operation is possible but can only be advised for those who fully understand the wiring techniques of their specific single phase motors and have the knowledge and experience to work out how to apply that to the reversing starter. Therefore reversing of single phase motors is not covered here.

Single phase motors may have a number of connections in their terminal boxes, for main windings, start windings, capacitors, klixons or PTC devices etc. Regardless of the number of terminals present, they will all feed back to a simple live and neutral feed at some point, and it is in this feed that the starter will be connected so it will not be necessary to interfere with any of these internal connections as would be necessary if dealing with a reversing starter. An example of the terminal arrangement for a single phase motor is shown below: The method of connection is similar to that of a 3 phase, except that for the motor overload to function properly all three poles must be populated.

This is because the overloads have phase loss protection, so expect to see similar current flowing in all three poles. If only 2 poles are populated live and neutralthe overload will sense no current in the third pole and trip accordingly this can occur in anything between a few minutes, even seconds, up to 2 hours, according to conditions and circumstances.

To prevent this the procedure is to run either the live or neutral it does not matter which through one pole of the contactor and overload, loop back up to go through a second pole in the contactor and overload and then to the motor.

The diagram below shows the wiring for a single phase motor and the path through the contactor and overload: Please see the attached diagram for guidance.

The branch breakers can be mounted in a separate distribution panel or can be incorporated into the main panel.

Particularly, GFCI should be in bathrooms, garages, kitchens, etc. The article Why, you may ask, do we need a 3-wire configuration? This is done in order to reduce energy losses in the cables.

Remember, power is volts times amps. When you double the voltage, you need half the current to deliver the same wattage. And for lower currents you can use lower conductor thickness.


As you can see from this wiring diagram, it is obtained from two VAC lines, so we have two voltage levels. Historically, U. It connects to the neutral bus in the breaker panel, which in turn is bonded to earth.

Likewise, old outlets which can still be found in many homes, had two holes instead of three.
