Some questions about isolation transfoemer

I have some questions about transformer. Adding a booster pump in front of the house gas water heater, if both two pumps were supplied by the isolation power supply(isolation transformer), as for the isolation power supply, it is the kind of 1: 1 transformer, Would it be possible to prevent electric shock? What power it is needed? I have read some basic priciple about transformer, the info from an article Transformer Basics and Transformer Principles (enclose the link https://www.kynix.com/Blog/487.html), a little confusing Confused . In reality, the situation is more complex. So is there any one can give some professional advice? Happy

Ask your electrician.

But as I've designed power electronics I can write that using an isolation transformer had NEVER prevented electric shock. It does what it does but you can still receive a shock under the right conditions. Your electrician is on the hook to do this right to remove the causes of electrocutions.

transformers are all "isolation"

In reply to: Some questions about isolation transfoemer

they are simply two coils of wire, around an shared iron core, but each coil is a separate circuit. It works by "inductance". For safety you should use a Ground Fault Interrupt device, which measures surge or voltage spike and breaks connection to help avoid overload and electrocution. A fast blow fuse is advisable too.
