Can anyone recommend a good isolation transformer for sale on-line?

** What kind ??

There are two:

1. Galvanic isolation - for use on a service bench.

2. Neutral conductor isolation.

Most you see offered for sale in the USA are of the *second* kind.

Surely an isolation transformer is just that - a one to one device with DC
isolation between windings. How it is subsequently configured is a
different matter. One use is where you can't be sure the line and neutral
of the supply are connected correctly - if they have a ground reference.
