A-330 pitot heat
The AF thread had me wondering what gauge wire powers the pitot heat. I do not have the 330 in my fleet. If any one out there find's themselves bored enough to have a peek in the AWM I would appreciate it.

Thx,

I suppose that is normal for modern aircraft our 777's are 20 gauge on a 5A CB.

Stating the obvious: Wire gauge will be a function of anticipated current and the length of the run from the power source to pitot.
