ONE MINUTE Premium Power Cable Survey

A note on survey design - allow more space for open-ended responses for why the questions do not apply.

In my case, because I use isolation transformers before power supplies. This does the same job, but better. These are results of experiment..

Way, I just re-read my comment and it was far too abrupt. Sorry about that. I was responding as if to a survey with public policy ramifications, done by a pro. Now you are suggesting Best Practice. Impressive. Thank you.
