With regards to electric shocks, How does an isolation transformer compare to the core balance(RCD) protection.

Maybe people will be reluctant to comment on a safety related question.
In my view an isolation transformer doesn't do much, give me a RCD anytime.
I'd have thought the RCD was cheaper too?

3 cups heavy cream

1 1/2 cups whole milk

2 vanilla beans, split lengthwise

1 cup plus 2 tablespoons sugar

6 egg yolks

2 1/2 teaspoon cinnamon

Combine cream and milk in a large sauce pan. Scrape in seeds from vanilla beans; add beans. Bring just to simmer. Whisk sugar and yolks in large bowl to blend. Gradually whisk in hot cream mixture. Return mixture to same saucepan. Stir over medium-low heat until custard thickens and leaves path on back of spoon when finger is drawn across, about 6 min. (do not boil). Strain into large bowl. Whisk in ground cinnamon. Chill until cold, about 3 hours.

Transfer custard to ice cream maker and process according to manufacturer's instructions. Transfer ice cream to a covered container and freeze until firm. (Can be made 3 days ahead. Keep frozen).

Shock not choc!!!!!

He/ She/it must try the ChocShock for size.

Ingredients

  • 2 cups white sugar
  • 1/2 cup cocoa
  • 1 cup milk
  • 4 tablespoons butter
  • 1 teaspoon vanilla extract

Directions

  1. Grease an 8x8 inch square baking pan. Set aside.
  2. Combine sugar, cocoa and milk in a medium saucepan. Stir to blend, then bring to a boil, stirring constantly. Reduce heat and simmer. Do not stir again.
  3. Place candy thermometer in pan and cook until temperature reaches 238 degrees F(114 degrees C). If you are not using a thermometer, then cook until a drop of this mixture in a cup of cold water forms a soft ball. Feel the ball with your fingers to make sure it is the right consistency. It should flatten when pressed between your fingers.
  4. Remove from heat. Add butter or margarine and vanilla extract. Beat with a wooden spoon until the fudge loses its sheen. Do not under beat.
  5. Pour into prepared pan and let cool. Cut into about 60 squares.

Your question is like saying "What is better at protecting you in a car crash, a seat belt or an asphalt highway?"

I think you are mistaken in thinking that an isolation transformer does ANYTHING with regards to protecting against electric shock. It doesn't. The giant transformer outside of your local utility distribution facility is an "isolation transformer", the output will fry you to a crisp.

A transformer which isolated you from 230V supply and provided a 55 volt -0- 55 volt output, with 0 tap earthed, IS an advance on 230V supply via RCD, especially if 110V side has RCD. I remember, long ago as a student, having a lecture from a government safety inspector who remarked on the awefull state of such 110 V wiring and the difficulty of enforcing better standards - because no-one had ever been killed on such a system!!
