Criteria for the purchase
These sockets deliver higher voltages and currents than conventional household sockets and are available in different sizes and designs. In this buyer's guide article, we'll provide you with some important criteria to consider when choosing a power outlet to ensure you're getting the right product for your needs.
Differences between AC and heavy current connections
Here are some important differences that exist between the regular AC power outlets and the high power power outlets. These make it clear how different the technical requirements and performance of the two connections are.
- Maximum Performance: 2,3 kW with alternating current / 6,5 kW with high current
- Fuse: 10 A with one fuse for alternating current / 3x 16 A with 3 fuses for heavy current
- Line cross-section: 1,5 mm with alternating current / 2,5 mm with high current
- Number of cores: 3 (N, PE, L1) for alternating current / 5 (N, PE, L1, L2, L3) for high current
Why 5 cores with heavy current?
In contrast to a 230 volt socket, a high-voltage socket uses three current-carrying wires that have a voltage of 400 volts between them.
A standard high-voltage socket has five connections: L1, L2, L3 for the current-carrying wires, N for the neutral conductor and PE for the protective conductor. The cores for the three phases are commonly identified with the colors black, brown and grey, while the neutral conductor is identified in blue and the protective earth conductor is identified in green and yellow.
performance and tension
Rating and voltage are the most important factors when choosing a heavy-duty outlet. It is important to understand the requirements of the application in order to choose the right outlet. Most of these sockets are able to deliver a power of up to 6,5 kW and have a correspondingly larger cable cross-section.
plug type
There are different types of plugs for high-voltage sockets. The most commonly used are CEE plugs. These are available in 3 and 5 pole versions. The 3 pin connectors are used for single phase applications while the 5 pin connectors are for three phase applications. You should ensure that you select the correct connector type for your application.
Protection class
The degree of protection is an important factor to consider when choosing a power outlet. The degree of protection indicates how well the socket is protected from dust, water and other environmental influences. The degree of protection is indicated by the IP protection class. Most sockets for a high-voltage connection have a protection class of IP44 or higher.
Cable cross section
Wire gauge is another important factor to consider when choosing a power outlet. The cable cross-section indicates how thick the cable must be in order to transport the required current. If the cable is too thin, it can cause overheating and damage. It is important to choose the right gauge wire to ensure the wire can carry the required current.
Quality
Quality is another important factor to consider when choosing an outlet for a power outlet. It is important that you choose a good quality outlet to ensure it is reliable and safe. A poor quality outlet can damage connected equipment or even cause fire.
Note on security
If you are planning to install electrical systems in your home, you should know that electrical installation is one of the trades that require a master craftsman in Germany. This means that the installation must be carried out by a master electrician. The duty of a master craftsman is intended to ensure that the electrical installations are carried out professionally and safely.
But don't worry, if you, as a practiced do-it-yourselfer, would like to carry out some of the work from the electrician's trade yourself, you can do this in consultation with a specialist company. However, it is important that you check with a professional beforehand to minimize any potential risks and ensure everything is done professionally.
So, before you lend a hand yourself, it is best to speak to an expert and get advice. After all, safety comes first.
