How at turn on can you have 4x nominal current? Inductor theory tells me at=
 t =3D 0=20
current =3D 0.

Not being critical, I'm just curious where your idea (rule of thumb?) comes=
 from. It's=20
not uncommon to hear people associating "inrush current" with inductance. I=
n AC=20
circuits it's a different ball game, assymetric currents due to phase angle=
 at switch=20
on etc.
