Vibration Heat effects on cables .

[Sweminer777]

What do Vibrations of the electricity cause in long term effect on different materials ?

Like 3MM copper wire, steel wire, aluminium wire .

Would it melt at 8KW of constants flow at 240 V ?

I've had some wires getting RED HOT at 1mm thick copper, pulling 120A on 240V psu.

You are running 120A through 1mm diameter wire? I'm surprised it doesn't just melt.

Looks like 120A would need something >5mm diameter.

I think you should have an electrician inspect that everything is done according to the Swedish electrical installation code.

Do it before you have a fire hazard.

Well it was from PSU and not direct from the walls.

Walls are pulling about 30A on 2.5mm copper wire.

Ok. I did not see it from the opening post. Sorry.

30A is way too much for 2.5mm2 (square millimeters) copper wire though..!

So you still need the electrician visit you and fix things.
