Hur mycket huvudsäkring i Engelska
Hej
Can someone tell me how much the mainfuse should be ?
In Holland there must be a different between the highest fuses in the powerboard and the mainfuse of 1,6 so if the fuse in the powerboard is 16A then the mainfuse should be 16 x 1,6 = 25A
Do you have that calculation too in Sweden ?

We dont have that kind of regulations in Sweden, if your mainfuse is 16A you can 16 in your powerboard as well.
No. There is (to my knowledge) no requirements as such regarding the main fuse (Huvudsäkring) and the fuses in the fuse box. It is completely normal to have main fuses of 16A and a stove also fused 16A.
Why do you ask?

OK thank you all.
What supprice me is the mainfuses.
Our meter with 3x16A mainfuses are outside the house and a cable runs from the meter into our house where we have 2 powerboards, one for own use and one for our visitors part
In total we have 8x16A and 33x10A fuses in the 2 powerboards and so far no problem and that supprice me and wil 3 x 16 mainfuse be enought for the future.
By the way how much is the fuse of the electric company ? Is that 25 or higher ?
Here it is 63A and in our houses we get by 1 fase of 35A and if you need 3 fase you get 3 x 25A

If you feel that 16 A aren't enough you can get bigger fuses and get a bigger monthly fee. I have not heard of any limit of the electric company, but I would guess it is 63A like in Holland.
You will seldom need more than 16 A from three fases.

As long as you don't use electricity for heating (directly) 3x16A i usually plenty. For specialized applications such as workshops with large motors (large bandsaws, planers and such) and welding gear you might need more. Modern appliances demand very little power.
Thanks again, this sound like my experience because 3 x 16A works fine so far but I also have 2 warmwaterheaters of 80L and 2 electric stoves, I don´t know if that can be a problem when both are in use ?
Suppose it is a problem how long does it take to raise the mainfuses ?

If the local grid is sufficient it's a matter of days (get hold of an electrician who switches fuses and reports to the grid owner). If not, which luckily is quite unlikely, it would take months and be extremely expensive.
You need an electrician to do the paperwork. The grid owner won't accept the form if it's not signed by a licensed electrician. If you let us know where you live I'm sure someone here can recommend an electrician.
The electric stoves are normally not a problem. Even in the unlikely situation that both are used fully (all heaters active) at the same time. The elements in them are normnally only active a few minutes for heating up, and then 10 - 30 s periodically.
The fuses can often take up to twice it's marking for 30 - 60 minutes.

Normally 3 x 25A is the highest you can get in a normal domestic installation. The wire gauge in the power board installation is typically matched for a maximum 25A (6 mm2). Higher than that is typically only for small enterprises, farms etc. You can of course get higher in a domestic installation but you will have to cover the cost of a thicker supply cable + new power board installation.Kallebo skrev:
