General information form for electrical contractors

Use this form to submit a request for the connection or metering of an electricity connection, to order a connection or metering work, to change the location of use, or to report the reduction of the main fuse size or the addition of small-scale generation to the electricity network.

Please note that we cannot connect a new or expanded electricity connection to the network until the site has an electricity connection contract. We charge any ordered work according to the current price list.

Electrical contractors: Please note the non-standard colour order.

The colour order of the distribution network is as follows: L1 = Black; L2 = Brown; L3 = Grey. When the connection cable is connected to the switchboard, the aforementioned colour order must be followed.

Ordered work or notification of implementation

Select an action
  • The connection will be connected to the electrical power network and the electrical meter(s) will be installed.
  • The connection may be new to your contract or an old, pre-existing one. For example, when a house is demolished and there is an existing 3x25A maintenance contract in place for the property and it is re-activated.
  • You need a new electricity meter, a new location of use.
  • Example 1: A commercial space or an apartment is divided into two, causing a need for a new electricity meter, a new location of use.
  • Example 2: A new building will be constructed on a property. The switchboard is located in a different building, with a rising electrical main that connects to the new building, where a new separate metering board will be located.

We will get in touch to discuss the locations of use/meter installations in more detail.

  • In multimeter sites, please send an attachment of the measuring center diagram(s) and rising electrical line diagram unless they have been sent separately by e-mail.
  • In current transformer measurements (fuse over 3 x 63 A), the central diagram must include information about the current transformer: E.g., 250/5A - 0.2S - 2.5 VA.

You may use the production equipment after installation. If any questions arise, we will be in touch.

Details of the change
  • For connections of more than 3 x 63 A, please attach the schematics of the switchboard/metering board.
  • For locations with several meters, please attach the schematics of the switchboard, metering board(s), substation and rising electrical mains, unless they have been supplied by the subscriber when making the contract or sent separately by e-mail.
  • For current transformer metering (fuse larger than 3 x 63 A), current transformer information must be shown on the schematics: transformer ratio, coupling, accuracy class, and load. E.g., 500/5A, 2-feed throughs connected. 250/5A - 0.2S - 2.5 VA.
  • Increasing the size of the main fuse of the connection requires making a new electricity contract for this purpose.
  • For locations with several meters, please attach the schematics of the switchboard, metering board(s), substation, and rising electrical mains, unless they have been supplied by the subscriber when making the contract or sent separately by e-mail.
  • For current transformer metering (fuse larger than 3 x 63 A), current transformer information must be shown on the schematics: transformer ratio, coupling, accuracy class, and load. E.g., 500/5A, 2-feed throughs connected. 250/5A - 0.2S - 2.5 VA.

  • Increasing the size of the main fuse of the connection requires making a new electricity connection contract for this purpose.

Board/work

Apartment buildings and other larger sites:

  • You must notify us if you want to have the construction site distribution board to be moved to the unmetered output of the switchboard!

Connection

The length of the service main means the length of the underground cable from the connection point to the switchboard. Usually this means from the boundary of the property to the switchboard.

You must include an attachment of the schematics of the substation when the site is not a detached or semi-detached house on a new, previously undeveloped property.

In all other cases, you must include the schematics of the substation with the service main drawn according to the implementation! This also applies to sites where a building that had been using the connection has been demolished and the service main remains partially intact.

Exceptions to this are connections where the connection point is located inside a building (e.g., a property transformer). In these cases, information about the length and type of the service main is sufficient.

Please note:

For the purposes of pre-processing and entering data in the information system, please enter the month/year of the estimated need for the connection/measurement.

The delivery time for connection/metering requests is approximately 7–14 working days from the call to the installer.

Details of the electricity connection and the contract owner

 
Registration notice

New location of use

The name, telephone number and e-mail address of the customer of the new location are not mandatory information, but will speed up the process. If there are several customers/contacts, please upload an attachment file with their information.

If there will be more than two metering systems, please attach the schematics of the metering boards with the details of each system. If necessary, we will request electrical diagrams of the additions of one or two locations of use that provide more detail about the new locations of use/electricity metering.

Direct metering = max. 3 x 63 A metering front fuse.
Current transformer metering = over 3 x 63 A metering front fuse.

Declare future changes to the place of use.

Please note! Metering related to changes is carried out as follows:

  • Direct metering = max. 3 x 63 A metering front fuse
  • Current transformer metering = over 3 x 63 A metering front fuse
  • When increasing direct metering = current transformer metering must be accompanied by schematics of the distribution board with current transformer information.
  • When increasing the front fuses of existing current transformer metering, the current transformers must be replaced (if necessary).
  • The replacement of the current transformers is not to be carried out independently, please contact the network operator in advance to arrange this.

We will contact you about the change in more detail!

Production mode

Classification of use

  • We require a sales contract for surplus electricity if the production equipment is used in parallel with the distribution network.
  • Classification of use LK4 = Use in parallel with the distribution network and sale of surplus electricity
Separation and labelling of production equipment
Protection of production equipment

Additional information and attachments

  • Semi-detached houses: If the main fuse of the connection is larger than 3 x 35 A, the switchboard diagram must be included, with the sizes of the front fuses of the metering visible.
  • Buildings owned by housing companies/property companies, etc.: In schematics of the switchboards/metering boards, everything must be marked on the network operators’ metering points measuring the apartments’ consumption of electricity in accordance with the articles of association. This also applies to other electricity measurements if the space/apartment to be measured is marked in the articles of association.
  • In current transformer metering (over 3 x 63 A), the data of the current transformer must be marked in the switchboard diagram. For example, 200/5A - 0.2S - 2.5 VA.

Upload an attachment with the following security information:

  • Excessive voltage protection 1: Setpoint and operating time
  • Undervoltage protection 1: Setpoint and operating time
  • Excessive voltage protection 2: Setpoint and operating time
  • Undervoltage protection 2: Setpoint and operating time
  • Automatic synchronization time of production equipment after mains voltage recovery (seconds)
