Thanks paul

Just to clarify the bottom row are all 20A MCBs.

& the cooker is actually 40A not 32 [Linked Image]

Just stumbled upon an interesting document: shows how seriously the ETCI (ElectroTechnical Council of Ireland) are taking RCD protection! Looks like we'll have consumer units full of the things if this proposal is accepted and made manditory in the wiring rules.

TC5: ETCI Safety Committee


TC5 is now focused on delivering on commitments detailed in its Strategic Plan 2003 - 2005, as follows:


* Complete the development of an intelligent RCD Tester (that can be plugged into any 13Asocket) that can be easily used to activate the RCD (on the distribution board) and determine if it is operating correctly (@30mAin less than 0.3 seconds). Time to trip will be indicated.


* Develop a new Guide on "The Principles of Electricity and Electrical Safety" and an associated training course. The guide will explain the basic principles of electricity, how it can harm and how to
prevent such harm. This Guide should, when completed, lead on towards the present Guide on "The Management of Electrical Safety at Work".


* Develop a Database for the recording and analysis of electrical incidents (fatal and non-fatal) and have it available on the ETCI website. It will be populated with a significant amount of information from past incidents (details of electrical fatalities from 1929 still available) and will detail the precautions that could and should have been taken to prevent or minimise the consequences.


* Recommend (to TC2) that all 230/400V electrical circuits be protected by independent RCDs, i.e. sockets protected by one RCD, lights by another
and fixed installations by one or more other RCDs. Smoke detectors and associated emergency lighting should make this proposal easier.

* Other work as appropriate and possible, e.g. study of fire incidents and keeping abreast with international developments (ISSA, ACOS, IEC)
