Hi All,

Since my "power" circuits got upgraded to the then gold standard 17th edition about 10 years back with all circuits on RCD or RCBO protection, I've consigned my plug in RCDs to the cupboard.

But I'm wondering if having a more local RCD (40 foot nearer the tool) is something worth doing if using electrics outdoors?

What does the team think?

TIA

Chris
You won't normally get any discrimination so either the local,
upstream or both could trip, however look at the follow ups to "F"
(Frank's) thread this morning, there could be an argument for an
"active" second RCD purely for the latching action.
