Ive read hours and hours of posts about electricity and still Im puzzled about the term "safe t cut'.

When posters talk about safe t cut, are they refering to a specific brand, or is it a generic term for a type of consumer unit?

We had the common Issan set up of a knife switch and a buss fuse for years, then 5 years ago, I got the local sparky to upgrade us to something a bit safer. He installed a ground rod and a real fusebox. The fusebox is not a safe t cut brand, but it looks the same. The main breaker is 63A with a test button, and there are 4 individual breakers. Because it is not safe t cut brand, does that mean it is less safe?

Safe-T-Cut are a Thai manufacturer of domestic electrical components http://www.safe-t-cut.com/en/

The term "Safe-T-Cut" has become synonymous with a front end RCBO installed to provide earth leakage protection to an existing installation. One of these http://www.safe-t-cut-rangsit.com/product_detail.php?pid=36

The fact that you have a "Test" button indicates that you already have earth leakage protection, no need to change anything

Thanks again, Crossy.

Just to say... When you have a brand that implies safety, they really should not be able to use the same "Safe-T-Cut" brand on the units that do not have RCD. Should be illegal to do that. I suggest not recommending the brand for that reason.

I have a Square - D box in my condo. The main breaker is Square - D size C50. Does Safe t Cut have a drop in replacement for this Main breaker?
