I will try a type B 20A unless anyone suggests otherwise.

A B20 (which would ok with 2.5mm^2 T&E in most cases), will allow 100A
of inrush current. A C16 will allow 160A of inrush.

(your current B16 allows 80A)

What kind of motor is in the saw - is it a loud universal brushed motor,
or a quite induction motor?


It is quite noisy 1600 Watt - so guess a universal brushed motor
