Hello, I am after a bit of help here regarding RCDs.
I have a Wylex split load consumer unit on a TT system (100ma T/D controlling light, cooker,immersion and 30ma controlling most sockets and outdoor circuits) but there isa cable coming from the TD RCD feeding a small two way consumer unit - a light and socket circuit . if a provided RCD protection to the socket circuit from the two way unit whether it be a standalone RCD or RCBO would it affect the T/D RCD in any way due to the fact it already has one RCD already in series with it?
Any help much apprciated.
