The Value of R.C.D.s

There have been many discussions recently about R.C.D.s, whether they really are necessary, and is an installation necessarily unsafe if it is old and has no, or insufficient, R.C.D. protection.

 

Well consider this please. If you are driving and need to brake hard to save somebody from injury or death does that incident ever get reported. If you knocked somebody over due to having bad vehicle brakes then it might.

 

If an R.C.D. operates correctly and saves somebody from injury or death, does that every get reported? There may have been 10s, 100s or even thousands of cases where an R.C.D. has saved somebody from injury or death, but we will never know the numbers because of a lack of reporting of the cases.

 

Personally I like the idea of R.C.D. protection

  • Look at it like this Zoom - if a BS3036/BS3871/BS60898 device disconnects within 0.4 seconds then yes RCDs are nice to have but are they necessary?

    Another way of looking at it given your car brakes analogy.

    Fully functional braking system? Yup, that works fine.

    Fully functional braking system with ABS? Also fine, but the absence of ABS in your braking system does not mean that your conventional brake set-up won't stop you.
