Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

This is Roger's photo of a 4mH inductor from a 3kw aerosharp.

If I'm after a 2mH inductor, with double the current rating, would it be ok to connect the 4 wires in parallel?

And if so, I imagine I would connect white and red together and blue and black together.

Is that right?

I don't know what's in that choke or how it's wound.

But in general yes, given two inductors of the same value, paralleling the inductors will halve the inductance and give you a higher current capability.
It's all too hard.

Looks the same as the 3rd one. The wire on that Big choke is 3 mm diameter.
Picture to see how its wound.

Ok I think I have to connect red and blue together and white and black together as the two coils are wound in different directions around the core.

Nope I think I was right the first time. So confusing
