Can a Variac Be Used as an Isolation Transformer?

Re: Can a Variac be an Isolation Transformer? NO a variac is a an autotransformer not a regular transformer.. Isolation has nothing to do with the ground pin.

Some isolation transformers are built with a turn ratio of 1:1. Such transformers are exclusively built to have the same input and output voltage and are used for isolation only. All transformers except autotransformers provide isolation.
