If you’ve ever heard of other people building their own DIY rotary phase converters, you might be tempted to try it out for yourself. While it might seem like a simpler, more cost-effective alternative to purchasing a phase converter from a reputable distributor, DIY phase converters are less safe, efficient, and cost-effective.

Whether you work in the agriculture, construction, or woodworking industry, consider the information below before attempting to DIY a phase converter.

DIY Phase Converters: 5 Factors to Consider

Are you considering building a homemade rotary phase converter? We strongly advise against it for five main reasons. Take a look below to see why building a DIY phase converter is never a good idea.


Anything that involves electricity naturally has some risks associated with it. Phase converters are no different. Building your own phase converter is risky for a few reasons.

  • You can get injured
  • You can get electrocuted
  • You can die

Building a DIY phase converter may also be against the law in your area. Considering the safety risks involved, it’s illegal in some jurisdictions for a non-licensed electrician to perform electrical work like building a phase converter. It’s simply a risk you don’t have to—and shouldn’t—take. It’s not worth the risk of a likely breakdown or potential physical harm.


Homemade phase converters are also less reliable than professionally manufactured ones. Unless you purchase a phase converter from a trusted supplier—like Phoenix Phase Converters—there’s no guarantee that it will operate reliably. You also can’t trust that instructions found online for building your own phase converter will be reliable.

While a DIY phase converter might be more cost-effective at first, it’s likely to malfunction more often and break down sooner than a phase converter from a trusted distributor—which will end up costing you more money in the long run. The lower upfront cost isn’t worth losing your peace of mind.


Homemade phase converters are less efficient. DIY rotary phase converters typically aren’t equipped with the latest technology available. This means they require more energy to operate at a normal rate, which causes your monthly energy bill to spike.

Industry Standards

Buying a phase converter ensures the product is compliant with all current industry standards and regulations, whereas building a phase converter doesn’t.

Phase converters and other electrical equipment must meet certain safety standards and regulations. The likelihood that a DIY phase converter will meet those standards and regulations is extremely low.

Expert Support

DIY phase converters don’t come with the perks of expert customer support and reliable product warranties. At Phoenix Phase Converters, product quality and customer care are our top priorities.

You can rest easy knowing you’re purchasing the highest quality phase converter on the market that requires little to no maintenance and will last for years to come. We also offer a competitive warranty for all of our products. Our experienced sales and tech support teams are always available to assist you.

Buying a Phase Converter: 5 Things to Know

Choosing which phase converter to buy can be complicated if you don’t know what to look for. Consider the following information before making a purchase.

Power Supply

The first thing to check before investing in or operating a single phase to three phase converter is that you have an ample power supply to operate it. A phase converter that lacks adequate power will not run efficiently. The lack of a power supply can also permanently damage the phase converter.

Load Type

Is your load light, medium, or heavy? Typically, the larger the equipment being powered, the heavier the load will be. That’s because larger equipment requires more power to operate. Below are some examples of equipment associated with each load type:

  • Light load: drill press and table saws
  • Medium load:  Computer Numerical Control (CNC) machines
  • Heavy load: HVAC equipment and refrigerators

Load Size

A phase converter’s load size includes its horsepower, amps, and kilowatts. We recommend investing in a phase converter that is twice the size of your intended load. This will ensure you always have plenty of power to operate your equipment. The Phoenix Phase Converters support team will help customize your phase converter to your specific power needs.

Indoor or Outdoor Use

Do you plan to use the phase converter indoors, outdoors, or both? Phase converters intended for outdoor use are more durable than those intended for indoor use because they must withstand various elements like:

  • Rain
  • Wind
  • Snow
  • Dirt

Similarly, phase converters used in the metalworking and woodworking industries should be protected from sparks, metal shavings, and sawdust. You want the phase converter to be protected against all possible damage in your work environment.

Product Distributor

When determining whether a phase converter distributor is reliable to purchase from, ask yourself a few questions:

  1. Is the distributor reputable in the industry?
  2. Does the distributor provide quality customer support?
  3. Does the distributor offer a product warranty?

If something were to go wrong with your phase converter, you want a distributor you can trust to have your back.
