FREE WEBINAR

John Peckham
The IET are producing a series of free Webinars on installation technical topics.


They are mostly aimed at the IETs registered Eng Tech electricians for their CPD but anyone can register for the Webinar.


If you are thinking about professional registration as an Eng Tech electrician then this might be a good taster session for you.


Here is the link to register  http://email.ietinfo.org/q/1IqPz1Z7I7eqPyKy3vrEZ/wv

    Thanks for that John - I've just viewed the recording.


    One of the questions was about 536.4.202 and 100A RCCBs - I wonder if the questioner had in mind the last paragraph of that regulation - "However, overload protection shall not solely be based on the use of diversity factors of downstream circuits..." and thus in the light of Mark's earlier example of a 63A or 80A RCCB in a split load CU being acceptable when the upstream fuse is presumably 100A - or whether an 100A RCCB might actually be required (manufacturer's instructions notwithstanding).
