Using a shore power isolation transformer at home?

Why are they not the same, from the electrical point of view?

Ultra/extreme isolation transformers are built to specifically reject high frequencies (noise) from passing through too.

Thanks!

I've looked at them a couple times but have never purchased. Remember one brand that advertised a 3.6 KVA unit at nearly half the weight of their 3.8. Never been quite sure if they are shielded (more noise rejection) and the plastic enclosure would retain more heat, although not significantly compared to a potted unit. More importantly, they've always been more expensive.

Transformers must be grounded continuously. Input, output and shield to chasis. Usually center-tapped secondaries to ground in balanced configuration as well.

Ngjockey, thanks!

Can you please clarify what do you exactly mean by "grounded input"? Shortening the neutral THAT COMES FROM THE PANEL TO THE TRANSFORMER to ground? Why is that a good idea? I've never heard of doing that (I am not very experienced with "pre-receptacle" wiring and might be wrong here: when you take something right from the panel, you can, probably, assume that ground and neutral are, essentially, the same).

Let me ask two more questions:
First, is it a better idea to have 2:1 transformer, converting 240 to 120?
Second, is it a good idea to add "enhanced grounding" via some buried rod?

Thanks!
