100mA RCDs TT system

Nikkid
Afternoon all,

What is the stance on using 100mA RCDs for TT systems now?

I was under the impression that they are no longer required as long as all circuits were protected by a 30mA RCD within the consumer unit (which in this case they will be).

Just looking for some clarity. 


Thanks!

    If it's a steel box a plastic rcd upfront is always reqd. It's the law.

    Oh no it isn't. It's perfectly possible to have Class II (double insulated) equipment with exposed steel parts. If you think otherwise please quote the appropriate legislation,
