Fuse in fuse box

Question

Can I change a fuse in my fuse box from a 30amp to 40/50 amp, if wires are 10mm

Oliver · Accepted Answer

Yes you can but work needs to be completed by a qualified electrician

Kevin · Answer

I assume you have changed the shower?  it depends if the cable has been sized for 30A taking into account length of run and correction factors when originally installed, a new calculation will have to be carried out to determine if the circuit breaker can be increased

Paul · Answer

Yes on a 10mm wire yes you can but please don’t do this until you have consulted a qualified electrician.

William · Answer

Hello Lisa, yes you can but what type of fuse box is it?

Ioannis · Answer

Hello, in a 10mm cable you can install up to 50A. But make sure is 10mm and not 6mm because on a 6mm you can go up to 32A

Ian · Answer

Hi, normally you can without any problems, however, this work should be carried out by an electrician as you are changing the characteristics of your fuse board. The amount of power that the cable can carry will be reduced if it is under insulation as an example.

Marcus · Answer

You sure can if it’s 10mm. I would recommend contacting a local electrician to make sure.
