  5. Hi Sikander; Just discovered your blog and find it to be very informative and useful, as I am in planning process of designing my retirement home in the Philippines. However I have a question. On your RCCB topic, it shows a single 2 pole RCCB, wired in series with multiple single pole MCB's. However if any of the downstream MCB's trip the RCCB, all of the MCB circuits will also be disconnected. Therefore, I wan to know how to wire-in several RCCB's, each supporting just a few downstream MCB sub-branches. Assume that all the RCCB's would be in parallel? Your expert guidance and advice is much appreciated.
    You can email me directly at "" or post your answer here, as I will continue to check it regularly. many thanks
