[QUOTE="Neil Holdsworth, post: 441270, member: 27520"] I've been asked to install additional sockets within dado trunking in a small office. It's currently being used for one computer but is going to have quite a few more. The problem is in somebody's wisdom they have fitted a 30ma trip upfront to protect the DB. Cables are run in mini trunking from the db to the dado trunking. Some of the sockets have two earth terminal in the dado and some don't, My proposal was to replace the RCD main switch to a normal switch. Replace any of the sockets not with dual earth terminals. Can anyone see a way round of not fitting an rcbo to these sockets as with all sockets requiring an rcd im worried about earth leakage tripping the rcbo. There isn't enough room in the mini trunking to add an additional circuit. Thanks Neil [/QUOTE]
