Main fuse services
You can increase or lower the amperage of a main fuse, replace a single-phase network connection with a three-phase connection, and change the location of the connection point. You can only order works from Elektrilevi.
A quick overview of your electrical system with the help of electricity test
Electricity test is a convenient opportunity for getting a fast and cheap initial assessment of your electrical system without the need to call an electrician. This unique digital service will help you to determine the load of the main fuse with the help of a remote meter, which will enable us to provide you with recommendations for reducing or increasing the amperage of the main fuse, and also for a more uniform distribution of load.
When should a main fuse be replaced?
This means that the main fuse amperage in your place of consumption is too low and you should increase it.
If your electricity consumption is lower than actually required, you should consider installing a main fuse with lower amperage.
Old main fuses might not be reliable, which is why we recommend to replace them with an up-to-date version. The fuse rating may remain the same.
Generally required if plots are being joined or divided.
A three-phase network connection is more modern, powerful and safe.
Use the main fuse calculator to find the appropriate amperage for your main fuse.
Increasing the amperage of a main fuse
The amperage of the main fuse should be increased if the fuses keep blowing while using more powerful electrical devices. When the amperage of the main fuse is increased, the fuse is changed at its existing location, while the supply point is not relocated.
Lowering and later restoring the main fuse amperage
You may consider lowering the main fuse amperage if you are using a package with a fixed fee and your electricity consumption has dropped significantly - for example, if you no longer use electric heating, have replaced your household appliances with new and more economical ones, etc. It is important to assess whether your electricity consumption has dropped permanently or temporarily (for example, if you are planning to bring in additional electrical appliances soon, which will lead to increased use of electricity, it is not reasonable to lower the main fuse amperage).
Transfer to a three-phase network connection
If you want access to more modern, powerful and safer electricity, we recommend that you replace a single-phase network connection with a three-phase connection, to switch from 1 x 20 A to 3 x 20 A for example. The service of transferring to a three-phase network connection is available both for detached houses and apartment buildings.
Adding and dividing main fuses
An existing main fuse can be divided when a property is divided. Main fuses on the same property can be added.
The main fuse is outdated
If your main fuse does not meet the modern requirements – you are still using an old-school fuse or an older circuit-breaker – then it is recommended to swap it out for a modern fuse with equal amperage for the sake of safety. Replacing the main fuse does not require changing its location.
Increasing the amperage of a main fuse
How much does it cost to increase the amperage of the main fuse?
The fee depends on the distance between the supply point and the low-voltage substation. If the distance from a low-voltage substation is up to 400 metres, one ampere costs 198 €. In case of connection points that are more than 400 metres from the low-voltage substation, the fee will be calculated based on the actual cost of the main fuse replacement. Additional costs for network reconstruction work may be added.
Distance between the connection point and a low-voltage substation | Fee per ampere |
---|---|
Up to 400 m | 198 € |
Over 400 m | Calculated based on actual costs |
A contract processing fee of 72 € will be added.
Important
When replacing the main fuse, the new main fuse will be installed at the same location. If the main fuse cannot be changed at its existing location, perhaps because there is no junction box or fuse base that meets the requirements or because the cables are old, you will have to upgrade your main fuse box and, if necessary, the electrical system inside your house. Once the required work has been done, we will install a main fuse of the amperage you have requested in the upgraded junction box.
Relocating the supply point
If you plan to improve the electrical system in your house or are already doing so, you can also ask us to relocate your supply point in addition to increasing the amperage of the main fuse. We will usually install a junction box at the border of the property and install a main fuse of the amperage you have requested. A cost-based fee of 1,000–1,500 € will be charged for relocating the supply point.
Where should the supply point stand relative to the house?
See here.
Lowering and later restoring the main fuse amperage
In the course of the work, we will replace your main fuse with one with a lower amperage. No refund will be issued for lowered amperes.
NB!Apartment buildings have joint main fuses, which is why apartment owners cannot request the lowering of the main fuse of their apartment.
How much does it cost to lower the amperage of the main fuse?
Amperage | Price |
---|---|
Up to 63 A | FREE |
Over 63 A | FREE |
Restoring the main fuse amperage
Sometimes it might be necessary to restore the main fuse amperage If the capacity of the network does not need to be increased, the main fuse amperage can be restored for up to three years from the date it was lowered.
The cost of restoring the amperage of a main fuse of up to 63 A costs 51.60 € on condition that the capacity of the network does not need to be increased.
For a main fuse over 63 A, the price depends on the actual costs.
Transfer to a three-phase network connection
If you want a three-phase network connection for a detached house
To transfer a detached house to a three-phase network connection you will have to fill in a request. We will then send you a quote. The work needed may be limited to installing a new main fuse and meter. In more complex cases, the network up to your house may have to be upgraded to a three-phase network. Order the service »
If you want three-phase network connection for an apartment
If you want a three-phase connection for your apartment and the supply point of the building is already three-phase, you do not need to fill in a request. You will have to send us the consent of your apartment association to building a three-phase connection for your apartment.
What should you do for the transfer?
The prerequisite for installing a three-phase meter is the existence of a three phase connection in the connection point of the apartment house.
- The installation of proper three-phase cabling from the junction box or connection point to the apartment's main fuse in the meter box
- The replacement of the apartment's single-phase main fuse with a three-phase one
- The installation of proper cabling for connecting the three-phase mete
How much does it cost to transfer an apartment building to a three-phase connection?
The largest expense is the cost of the electrical work, such as the replacement of the cabling, etc. Elektrilevi does not carry out this work, which means you will have to order them from a company qualified to do the electrical work. The work we carry out in the apartment building is:
Work | Price |
---|---|
Installing the meter | 61.20 € per apartment |
Sealing | 4.80 € per apartment |
How to order?
To order a three-phase meter, email [email protected] or write Elektrilevi OÜ, Veskiposti 2, 10138 Tallinn. Please enclose the consent of the apartment association or the residents of the house with your request.
NB!
Adding and dividing main fuses
Adding main fuses
If you have two or more supply points on your property, they can be added or merged.
Example: A house has a single-phase connection with a 16 A main fuse and an ancillary building has a three-phase connection with a 16 A main fuse. These main fuses can be added to form a three-phase connection with a 32 A main fuse.
Dividing a main fuse
If the number of electricity consumer has increased and the amperage of the existing main fuse is too low, it might me necessary to install a new connection point.
How much does it cost to add or divide the amperage of a main fuse?
The price of the service depends on the actual cost of equipment, materials and work.
