Power current: everything you need to know

Thanks to the higher voltage and the use of multiple phases, power current is very suitable for applications where a lot of energy is needed at the same time. In this text, you will discover exactly how power current works and what it is all used for.

What is power current?

Power current is a form of electricity supply where you use multiple phases simultaneously, so more power is available than with a standard connection. It works because there are three separate power wires (phases), each connected at a different angle.

This allows a device to benefit from a higher overall voltage and a more stable power supply. In practice, this means that power current is suitable for high-energy applications, such as large electric machines or intensive use of tools, without having to worry about voltage loss or overloading.

Voltage of power current

Power current operates at a standard voltage of 400 volts (V). This is because three phases are used, with the voltage between two phases being 400V. This is an important difference from a regular 230V connection, which uses only one phase. The difference between 230V and 400V is as follows:

• 230V connection: used for standard household appliances, lighting and electronics.
• 400V connection: suitable for high-power devices such as industrial machines, heavy kitchen appliances and electric vehicle charging stations.

Although both voltages are common in homes and businesses, a 400V connection is necessary if you want to use powerful appliances safely and efficiently.

Applications of power current

Power current can be used in a variety of situations, from domestic use to large-scale industrial applications. With its higher voltage and ability to deliver more power, power current provides a stable power source for demanding appliances.

Household applications

Even in and around the house, there may be appliances that require higher power than what a standard connection offers. Power current can then be a godsend, especially if you have multiple energy-intensive applications.

• Electric stoves or (induction) hobs
• Electric vehicle charging stations
• Heavier tools for jobs
• Higher power heat pumps and air conditioning

Thanks to power current you have more capacity at your disposal and you prevent overloading. Keep in mind that you do need an appropriate connection to use this safely.

Industrial use of power current

In industrial applications, power is almost indispensable because of the constant demand for high power and a stable power supply. This can range from small workshops to large manufacturing facilities.

• Large engines and heavy machinery
• Metalworking, such as welding and grinding
• Cooling systems and compressors
• Production lines with continuous energy requirements

With power current, you can keep these industrial processes running smoothly and without interruptions. In this way, you make optimal use of the capacity of your equipment and reduce the risk of breakdowns.

Power current is not a 3-phase connection

Power current and a 3-phase connection are often confused with each other in practice, but they are not necessarily the same thing. A 3-phase connection is simply the way electricity enters your home or business, with three different phases, each supplying 230 volts. With power current, the voltage between these phases is used, giving you a total voltage of 400 volts.

However, most households in the Netherlands still use a single-phase connection of 230 volts, sufficient for standard appliances and lighting. A 3-phase connection is useful for situations in which the capacity of one phase is no longer sufficient, for example with heavy electrical installations or multiple appliances that use a lot of power at the same time.

Cost of installing power current

The cost of a power connection can vary greatly, depending on your grid operator, the existing infrastructure, and the modifications required in the meter box. This often involves both material and labor costs, and in some cases, the grid operator must increase the weight of the main connection. This can mean replacing the cable from the street to your home or business, which affects the total price. As a result, the investment can run from several hundred to thousands of dollars.

A conversion of an existing installation often involves more than just installing new cables and outlets. Additional groups may need to be placed in the meter box and a new meter suitable for 3 phases installed.

You may also have to request an increase in the main fuse, which entails additional time and costs. Therefore, always get a clear quote from a licensed installer and consult with your grid operator to avoid unexpected costs and delays.

Applying for power current: where to start?

Requesting power current usually starts with contacting your grid operator. It is important to first check whether your current connection is suitable for the switch to 3 phases, or whether an increase in load is required. Below is an overview of the steps you usually need to go through to arrange for power electricity.

1. Check with your grid operator: contact your grid operator to find out if a 3-phase connection is available at your location and what the options are.
2. Request a quote: in many cases, you will need to make a formal request through your network operator. This will help you understand the cost of expanding or increasing the size of your connection.
3. Schedule the work: after agreeing to the quote, an appointment will be scheduled for any adjustments to the main connection and meter box.
4. Engage a licensed installer: make sure the installation in your home or business is prepared for the new connection and meets all safety regulations.
5. Check delivery: after the installation, you and the installer test that everything is working properly so that you can use power current without problems.

Requesting power power is a step-by-step process, starting with the grid operator and ending with a thorough inspection of the installation. By being well prepared and bringing in the right parties, you'll ensure that the transition to power current goes smoothly and safely.

Installing power current

Installing power current requires a careful approach because you are dealing with higher voltages and a greater load on the electrical system. In many cases, it is wise to hire a licensed installer to ensure that everything is connected safely and according to current standards.

In addition, it is important to check in advance that all the necessary components are available, from the right cables to a suitable meter box. Here are some aspects to consider when installing power current:

• Provide appropriate cables and materials suitable for higher voltage and loads.
• Check if your meter box has enough space and capacity for additional groups.
• Observe grounding and safety precautions to minimize electrical hazards.
• Use a qualified and licensed installer for a competent connection.
• Always perform a check or inspection to ensure operation and safety.

By proceeding carefully and making the proper preparations, you will avoid dangerous situations and ensure a safe, reliable power installation that meets all requirements.
