Will a 10mm PYRO take 80 amps ?

[sycamore89]

Hi,

I need to change the main incoming fuse from 60A to 80A but there is a 10mm pyro feeding the property and i dont really want to replace this. The reason I need to up the supply to 80A as I am installing a sunbed which runs at 40A single phase. The load will never constantly be running at 80A so thought that the 10mm pyro would be sufficent.

Property has 2 rings with only a few computers and hairdryers etc.... has no oven but 1 microwave so not much load on any other circuits.

Would this be ok ?

I have not pulled the DNO fuse yet but I will do for safe isolation while I change the cu! Property is fed by a 25mm SWA! And no I'm not a sparks I'm a plumber !!!

Could be a Ryefield board with a 60A fuse in, and a 100A DNO fuse.
