The inrush for an induction motor can be enough to dim the lights for

My bench saw does, 1.2kW induction motor IIRC. No soft start either so it
makes quite a bang in itself as well as dipping the lights.

Depends. When I had a 1947 vintage lump of iron up a pole to supply me
the microwave would do that all on its own.

Our "800W" microwave and the Dyson vac does that as well not as much as
the bench saw though, though the Dyson is close.

The pole transformer is quite small probably only rated at 100A. We do
have some E7 heating but I suspect that when that was put in by one of
the previous owners they didn't bother telling the REC...
