This detailed article by Rod Elliot explains why using an iso is
hazardous - not that reading it will have the slightest impact on
wooden heads like you or NT.

FYI:

The use of an RCD, ELCB or other earth leakage detector
( aka safety switch) on a workbench is a safety essential.



I think the point in this thread is that one has to know what they are dealing with before employing an isolation transformer.


** Which practically counts out the servicing equipment with unknown faults..



I read the article.


** Good for you.

IMO, the article title is an attention getting and his point is that the isolation transformer presents a 'false sense of safety'. The assumption that most ppl will make is that one blindly needs to install an isolation xformer in all applications and it will keep you safe. There are limitations based on the circuits one is dealing with.

The assertion to be safe one must "use of an RCD, ELCB or other earth leakage detector" is a general statement but also a bit misleading. RCDs are NOT recommended and ELCBs are essential.


** The use of RCDs is highly recommended in the article *YOU* cited !!!!

The statement about live chassis 'only in TV of the 90's' is grossly
incorrect.


** Good - cos no-one here actually said that.

Never mind, NG postings are notorious for being confusing & difficult to follow.
